Check for unintentional plagiarism

Easily check your paper for missing citations and accidental plagiarism with the EasyBib plagiarism checker. The EasyBib plagiarism checker:

  • Scans your paper against billions of sources.
  • Identifies text that may be flagged for plagiarism.
  • Provides you with a plagiarism score.

You can submit your paper at any hour of the day and quickly receive a plagiarism report.

What is the EasyBib plagiarism checker? 

Most basic plagiarism checkers review your work and calculate a percentage, meaning how much of your writing is indicative of original work. But, the EasyBib plagiarism checker goes way beyond a simple percentage. Any text that could be categorized as potential plagiarism is highlighted, allowing you time to review each warning and determine how to adjust it or how to cite it correctly.

You’ll even see the sources against which your writing is compared and the actual word for word breakdown. If you determine that a warning is unnecessary, you can waive the plagiarism check suggestion.

Plagiarism is unethical because it doesn’t credit those who created the original work; it violates intellectual property and serves to benefit the perpetrator. It is a severe enough academic offense, that many faculty members use their own plagiarism checking tool for their students’ work. With the EasyBib Plagiarism checker, you can stay one step ahead of your professors and catch citation mistakes and accidental plagiarism before you submit your work for grading.

Why use a plagiarism checker? 

Imagine – it’s finals week and the final research paper of the semester is due in two days. You, being quite familiar with this high-stakes situation, hit the books, and pull together a ten-page, last-minute masterpiece using articles and materials from dozens of different sources.

However, in those late, coffee-fueled hours, are you fully confident that you correctly cited all the different sources you used? Are you sure you didn’t accidentally forget any? Are you confident that your teacher’s plagiarism tool will give your paper a 0% plagiarism score?

That’s where the EasyBib plagiarism checker comes in to save the day. One quick check can help you address all the above questions and put your mind at ease.

What exactly is plagiarism? 

Plagiarism has a number of possible definitions; it involves more than just copying someone else’s work. Improper citing, patchworking, and paraphrasing could all lead to plagiarism in one of your college assignments. Below are some common examples of accidental plagiarism that commonly occur.

Quoting or paraphrasing without citations

Not including in-text citations is another common type of accidental plagiarism. Quoting is taking verbatim text from a source. Paraphrasing is when you’re using another source to take the same idea but put it in your own words. In both cases, it’s important to always cite where those ideas are coming from. The EasyBib plagiarism checker can help alert you to when you need to accurately cite the sources you used.

Patchwork plagiarism

When writing a paper, you’re often sifting through multiple sources and tabs from different search engines. It’s easy to accidentally string together pieces of sentences and phrases into your own paragraphs. You may change a few words here and there, but it’s similar to the original text. Even though it’s accidental, it is still considered plagiarism. It’s important to clearly state when you’re using someone else’s words and work.

Improper citations

Depending on the class, professor, subject, or teacher, there are multiple correct citation styles and preferences. Some examples of common style guides that are followed for citations include MLA, APA, and Chicago style. When citing resources, it’s important to cite them accurately. Incorrect citations could make it impossible for a reader to track down a source and it’s considered plagiarism. There are EasyBib citation tools to help you do this.

Don’t fall victim to plagiarism pitfalls. Most of the time, you don’t even mean to commit plagiarism; rather, you’ve read so many sources from different search engines that it gets difficult to determine an original thought or well-stated fact versus someone else’s work. Or worse, you assume a statement is common knowledge, when in fact, it should be attributed to another author.

When in doubt, cite your source!

Time for a quick plagiarism quiz! 

Which of the following requires a citation?

  • A chart or graph from another source
  • A paraphrase of an original source
  • Several sources’ ideas summarized into your own paragraph
  • A direct quote
  • All of the above

If you guessed option E than you’d be correct. Correct punctuation and citation of another individual’s ideas, quotes, and graphics are a pillar of good academic writing.

What if you copy your own previous writing?

Resubmitting your own original work for another class’s assignment is a form of self-plagiarism, so don’t cut corners in your writing. Draft an original piece for each class or ask your professor if you can incorporate your previous research.

What features are available with the EasyBib plagiarism checker? 

Along with providing warnings and sources for possible plagiarism, the EasyBib  plagiarism checker works alongside the other EasyBib tools, including a grammar checker  and a spell checker . You’ll receive personalized feedback on your thesis and writing structure too!

The  plagiarism checker compares your writing sample with billions of available sources online so that it detects plagiarism at every level. You’ll be notified of which phrases are too similar to current research and literature, prompting a possible rewrite or additional citation. You’ll also get feedback on your paper’s inconsistencies, such as changes in text, formatting, or style. These small details could suggest possible plagiarism within your assignment.

And speaking of citations, there are also  EasyBib citation tools  available. They help you quickly build your bibliography and avoid accidental plagiarism. Make sure you know which citation format your professor prefers!

Great! How do I start? 

Simply copy and paste or upload your essay into the checker at the top of this page. You’ll receive the first five grammar suggestions for free! To try the plagiarism checker for free, start your EasyBib Plus three-day free trial.* If you love the product and decide to opt for premium services, you’ll have access to unlimited writing suggestions and personalized feedback.

How you can avoid plagiarizing

ILLUSTRATION

Know the different types of plagiarism

There are several types of plagiarism, and it’s essential to understand the differences to avoid making these mistakes and prevent plagiarism in the classroom.

  • Direct plagiarism: Using someone else’s exact words and using them as your own with no credit to the source. Eliminating portions of the text still qualifies as direct plagiarism.
  • Patchwork plagiarism: Creating new text by combining exact phrases or sentences from multiple sources without acknowledging the original authors or sources.
  • Self-plagiarism: Attempting to reuse or recycle your previous work and claiming it as a new piece of work without mentioning the source of original publication.
  • Source-based plagiarism: Producing false sources within your writing or omitting one or more references from citations.

Cite your sources

Students often think of citations as a simple means of acknowledging another author's work. While this is their main purpose, there are other benefits as well.

Source citations also show readers where to go to learn more. By providing context around the citation in student papers, such as the source medium and when it was published, readers can locate the information more easily. Giving too little source information or improperly formatting it can result in unintentional plagiarism. These mistakes also make it difficult for readers to locate the original source and verify information.

Quetext's citation generator makes it easy for students to accurately cite their sources without slowing down their writing process. Once a user inputs the text, the software identifies the passages that require a citation and subsequently generates it in the style required — APA, MLA, or Chicago.

Always use a plagiarism checker

The best way to avoid severe plagiarism consequences is to use a plagiarism checker. Often, plagiarism is unintentional and results from poor paraphrasing of material found online. Using a plagiarism checker, the student can avoid accusations of any kind of plagiarism and benefit from a close review of the original material.

Quetext's plagiarism checker provides a speedy, easy process for students to receive accurate results, identifying areas of concern and providing on-page solutions.

Plagiarism Checker for Students FAQ

What are the consequences if a student is caught plagiarizing.

The consequences of plagiarism vary according to the student’s academic institution and grade level. For example, a middle school student who plagiarizes within an essay may receive a stern warning and additional instruction related to the process of citing sources or summarizing one’s thoughts.

However, students in higher education institutions guilty of plagiarism in academic papers face much steeper repercussions, including, but not limited, to failing grades and disciplinary or legal action. Factors such as the assignment itself, the instructor, and whether or not it is your first offense impact the outcome.

Depending on the severity of the situation, plagiarism can also impact a student’s reputation or future career opportunities.

How does a plagiarism checker help students?

A plagiarism checker helps students be proactive in finding instances of plagiarism before an assignment is completed and turned in with no way to correct the errors.

In addition, by identifying the potential conflicts early, students can conduct further research to find alternative sources to understand the material better and revise or rewrite the offending passages.

Plagiarism checkers also help students learn innovative writing techniques, improve their writing skills through better research and experience in summarizing ideas, and preserve academic integrity.

Do teachers use plagiarism checkers?

Many teachers use plagiarism checkers to ensure a student’s submission is 100% original work. With the rise of easy-to-use tools like Quetext, checking for authenticity and text matches is a quick and affordable process to scan millions of online data sources.

Using plagiarism checkers also allows teachers to educate their students on the importance of citing sources and the ethical responsibilities of research and opinion writing.

Plagiarism has always been a source of concern for teachers, but until now, options for manual detection have limited their opportunities to identify the problem efficiently. However, the evolution of technology in this area has made the tools more accessible than ever.

How do teachers check a paper for plagiarism?

Teachers are skilled at detecting plagiarism, especially those who have been teaching for a significant period or who teach in the areas of English or Literature. Some teachers use a simple technique of entering a sentence into a search engine to find instances of duplicate text on web pages.

However, this manner of plagiarism detection is manually intensive and dependent upon unreliable algorithms. Some may use their writer’s intuition by identifying anomalies in sentence structure, inconsistencies in vocabulary or grammar, or a combination of all of these.

Others use more sophisticated and robust plagiarism detection software, like Quetext. Quetext can scour millions of sites using DeepSearch™ technology to identify plagiarism in seconds. These tools also enable instructors to work with students to improve their writing and avoid repeating the same mistakes in the future.

Can students get in trouble for accidental plagiarism?

Yes, students can be penalized for plagiarism, even if it was an accident. Unfortunately, instructors have no way of knowing the intent behind plagiarism. Depending on the type of plagiarism, instructors may allow leeway for students to learn from their mistakes and correct the work without the threat of severe consequences.

However, repeat offenders are less likely to receive this flexibility and may face steeper penalties. Additionally, instructors of college-level courses with clear plagiarism guidelines and policies may be less inclined to let students off the hook and instead enforce severe consequences.

Is there a free plagiarism checker for students?

Yes! Quetext offers both a free and a paid subscription for students to seamlessly verify their writing. Quetext goes beyond traditional plagiarism checkers to provide students with advanced technology that puts content through three layers of evaluation in just a matter of seconds. This level of insight enables students to understand the degree to which the text has been plagiarized and decide whether to rewrite the text or use the citation assistant to cite sources.

Quetext also offers a detailed report students can use to document their editing efforts and present as proof of a plagiarism-free, 100% original content document.

Quetext's plagiarism tool also offers flexible pricing for its Pro features which facilitates the citation of online sources, attributions, and real-time feedback for writing improvement.

How can a student check for plagiarism?

Anyone can enter the text from a research paper into a search engine and find potential matches that identify instances of plagiarized content or duplicate content. However, this method is largely ineffective and does not identify every area of concern.

Students can use Quetext's free online plagiarism checker by creating an account, copying and pasting the text in question into the plagiarism checker, and receiving a comprehensive analysis with color-coded feedback, a plagiarism percentage score, and options for editing the text.

Quetext is one of the best plagiarism checkers available with high-quality insights and accurate results.

💯 12 Online Plagiarism Checkers

🔗 references, 🤔 why use a plagiarism checker.

The issues of plagiarism and academic dishonesty become more and more relevant each year. According to some research , 92% of surveyed students stated that they had or knew someone who had cheated .

So, why does this happen?

The researchers have shed light on this phenomenon, and here are some of their statistics:

  • 92% of those who plagiarized stated that they did so because they wanted better grades.
  • 83% said that they cheated because of procrastination.
  • 75% of respondents pointed out that they did not have enough time to finish their assignments.
  • 33% have attempted to cheat due to their overloaded class schedule.
  • 58% of the surveyed have plagiarized because they lacked an understanding of the subject.
  • 50% had little or no interest in the subject.
  • 25% of participants believe that anyone can cheat without any consequences.
  • 17% of the interviewees cheated because of peer pressure.
  • Another 17% think that it does not matter to the professor if their paper is plagiarized.

After taking all of these numbers into account, it is evident that a significant percentage of students commit acts of plagiarism for several main reasons. Among them are poor time management, concern for academic performance, and peer pressure.

Now that you know the causes of plagiarism, it will be beneficial to examine its different types. Generally, these can be divided into two groups: unintentional and intentional.

Intentional Plagiarism

When it comes to intentional plagiarism, it doesn’t necessarily mean that your paper copies the full document written by someone else. This is only one example of cheating out of many others.

Unintentional Plagiarism

Meanwhile, unintentional plagiarism may refer to:

  • Forgetting to cite a source when describing something that is not common knowledge.
  • Not citing information that you have paraphrased or summarized.
  • Failing to use a proper citation style when documenting sources.
  • Misquoting an author, even if it is appropriately cited in the paper.

When composing your paper, it is important to stay vigilant. This is why it is handy to utilize the help of our plagiarism checker (2000 words). Free detection software is a quick and easy way to confirm your paper’s originality.

🔍 How to Check for Plagiarism

As you work on your paper, you may start to ask yourself: How can I avoid plagiarism altogether?

Below, we have prepared some tips that will help you write a 100% original essay:

  • Regulate your time. As mentioned earlier, procrastination and a full class schedule may lead to plagiarism. To stay on top of everything, don’t put off urgent tasks until tomorrow. Read up on time management techniques and figure out an efficient study method that works for you.
  • Cite while you write. Get in the habit of citing sources in full as you write your paper. Firstly, doing this will save you plenty of time for putting together a bibliography. Second, it will significantly decrease the risk of an improper citation.
  • Use only trusted sources. There are a lot of websites with questionable content. Even documents that seem scholarly at first could turn out to be another student’s paper. Ascertain that you understand the source and the ideas that it is trying to convey.
  • Understand the difference between various citation styles. An improper citation may result in a penalty for plagiarism. So, make sure you rely on a high-quality reference guide and implement the correct style. Don’t forget to add quotation marks when using unchanged phrasing from the source.
  • Use plagiarism scanners before you submit your paper. Even if you wrote your piece from scratch, we still advise you to double-check it. From time to time, you might unintentionally “borrow” a couple of phrases that appear in other works. Despite it being an accident, your professor might penalize your paper. To avoid this, you can use one of the online free plagiarism detectors.

Perhaps our free plagiarism checker (2000 words & more) wasn’t exactly what you were looking for. If you find yourself in need of a tool with slightly different features, this section is for you!

Below, we have prepared a list of 12 online plagiarism scanners , both chargeable and free. They will allow you to avoid similarities with other works on the Internet.

Scribbr is a plagiarism checker powered by Turnitin, a plagiarism-detection system used by most universities. Therefore, it is an excellent choice for those seeking access to Turnitin but not being able to get it. Scribbr offers a free version, but it only allows you to see whether your paper contains potential plagiarism. To see a full report, you have to go premium, which starts from $19.95 per document.

2. Grammarly

Grammarly is famous for its superior grammar-checking software. However, with a paid version, you’ll also get access to its plagiarism detector. It can check your paper against billions of web pages, but its detection doesn’t cover gated and academic content. It also fails to identify rephrased content.

3. PlagScan

PlagScan is an outstanding plagiarism detection tool that is useful for students and writers alike. The website compares your paper against web sources, journals, and internal repositories. It doesn’t offer a free plan, but it allows you to check your first 2,000 words without charge during your free trial.

4. PaperRater

PaperRater is another plagiarism detection service. It operates as freemium software and provides you with a free report. The chargeable version allows you to get a printed summary of your results that contains more detailed information. This program is also integrated with a proofreader and supports various file types for upload.

5. Plagiarisma

Plagiarisma is a simple and free tool for students to use. It works with Google, Yahoo, Bing, and Scholar databases. Don’t forget to register to check your paper!

6. Dupli Checker

At first glance, Dupli Checker is similar to those mentioned above. However, this website has extra features, such as a text spinner, spell checker, word counter, etc. Of course, it also detects plagiarism and provides you with stats, links to plagiarized URLs, and highlights of related phrases. Did we mention that it’s free?

Viper , also known as ScanMyEssay, is a plagiarism detector supporting 56 languages. It checks your content against over 10 billion sources and can scan multiple files at once. Viper offers a free trial, allowing you to check one document of up to 5,000 words. It’s a good option for students who need to scan their papers for plagiarism occasionally.

8. PlagAware

PlagAware offers high-quality plagiarism detection and checks your papers against over 70 billion sources! It has a free plan that allows you to scan 10 pages per month. Moreover, if you choose a premium plan, you pay only for the first check of every document, while subsequent scans of the revised versions are free.

9. Copyscape

Copyscape is a plagiarism detector that can check your paper against online sources and web pages. It doesn’t check your content against academic databases, books, scholarly journals, and offline sources. So, it’s suitable for online content creators and website owners, while students seeking to check academic writing should opt for something else.

10. Copyleaks

Copyleaks offers both free and paid accounts to its users. In both cases, you have to register to use this service. If you have a free account, you can upload up to 2,500 words per month and use two checks. You will also see the history of your previous plagiarism scans.

11. Quetext

Quetext is a user-friendly plagiarism checker that allows you to edit text directly within the tool and has a useful feature — a citation assistant. However, you can check only 500 words with their free plan. After exhausting this limit, you have to go premium. It can also fail to identify plagiarism from scholarly sources like student dissertations or journal articles.

12. SmallSEOTools

The last paper plagiarism checker tool in our list, SmallSEOTools , allows you to check up to 1000 words per search for free. The amazing thing about this tool is that it’s available in English, Chinese, Russian, Italian, French, Portuguese, Spanish, German, and Japanese languages.

Remember – for students, getting caught plagiarizing may mean a failing grade, suspension, or even expulsion. For professionals, the stakes are even higher. Therefore, make sure to use our plagiarism checker for 100% accurate results!

Jesse Rumball-Smith - testimonial

I just wanted to say thank you for such a great and free service, all the other grammar checkers and writing assistants I have tried don’t have nearly the depth of features let alone all available on a free subscription. As a student with little income available I am extremely grateful that unlike all others companies you don’t limit features on the free plan. This is a fantastic product and given the income I would definitely upgrade to the premium. I've let all my fellow students know about Trinka as it is seriously a life saver.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

Necessity of AI Plagiarism Checker Over Time

DupliChecker's AI plagiarism checker utilizes artificial intelligence to enhance the precision of detecting plagiarism by analyzing various text elements, such as syntax, writing pattern, tone, and rhythm of words. This inclusion of AI simplifies to check AI plagiarism across different domains.

How Does AI Plagiarism Checker Differs from Traditional Methods?

The working of an AI plagiarism checker differs from traditional methods as it organizes your data and analyzes it with advanced machine learning and Natural Language Processing techniques. Later, this AI plagiarism detector compares the comprehended information with millions of web pages’ data available in its databases to find similarities. Lastly, it displays AI plagiarism detected in your content while letting you know its exact percentage. This entire method differs from traditional plagiarism detection methods that use string-matching techniques and provide an approximate estimation of plagiarism that needs to be more accurate.

Plagiarism detector VS Manual checking [Pros and Cons]

It’s boring, time taking and the big thing is the MANUAL! Ah

Who wouldn’t want to skip doing something that technology can do for you with more accuracy and quickly? Right!!!

We know We would! As it can help in many ways, one of which is finding a copy of original content over the internet and informing about it while you are sipping your coffee in dim light, “Sounds Cool”. Or you can go ahead and crosscheck to look for the plagiarized work manually which not only is going to take a lot of time. You need an excellent memory because while reading so many documents you might keep on forgetting the duplication and sources.

Isn’t it enough reason why a plagiarism scanner is used?

Because it is accurate and able to find the copied content real fast to improve academic honesty and whatsoever that does not allow plagiarism. This usually happens in almost every student, professional writer, professor, or content creator’s life that uses the internet to study, teach or deliver their work.

So, they have to be very careful in uploading a part of their work online; the best way is the use of image formation. If someone copies from the image we have developed a tool to find similar image . It will recognize objects on the image and let you know where this object or image is located. In which no one can copy any sort of work, but they will have to write down which people mostly don’t like to do.

Plagiarism in the digital world.

The most common problem in plagiarized content has to face is expulsion from the Search Engine Result Page (SERP), and websites that are aiming for a better rank can’t afford that.

Therefore this plagiarism checker will inform you after detection of all the areas of the internet where it finds similarity or duplication in the content.

In the world of the internet, it is not considered a crime, but it just shows deceitfulness in that person’s character. The question is why does it matter? Well, in academics, it can put people into serious trouble, if caught plagiarizing, they will not only face punishments but lose the time a beginner can utilize to learn.

In this cyberspace, there can be many mistakes that can trigger duplication in content.

How to Check for Plagiarism: Ensuring Your Work is Original

Plagiarism is a serious issue, both in academic and professional settings. It involves using someone else’s ideas or words without properly citing them. Fortunately, there are several tools and techniques available to help you check your work for plagiarism before you submit it.

Here’s a guide to navigating plagiarism checkers and ensuring your writing is original:

Understanding Plagiarism Checkers:

  • What they do: Plagiarism checkers are software programs that scan your text against a massive database of web pages, articles, and academic journals. They identify any significant matches, highlighting potential plagiarism.
  • Peace of mind: Knowing your work is original reduces stress and avoids accusations of plagiarism.
  • Catching unintentional mistakes: Even paraphrasing without proper citation can be flagged, prompting you to double-check your references.
  • Not perfect: Plagiarism checkers are powerful, but they can’t catch everything. For instance, they may miss paraphrased content that retains the original meaning.
  • Limited databases: Free checkers might have smaller databases, potentially missing less common sources.

Using a Plagiarism Checker:

There are several free and paid plagiarism checkers available online. Here’s a general process for using them:

  • Choose a checker: Consider factors like features, database size, and cost. Free options are great for basic checks, while paid services might offer more in-depth analysis.
  • Upload your text: Most checkers allow you to copy and paste your text or upload a document file.
  • Run the scan: Initiate the plagiarism check and wait for the results.
  • Analyze the report: The report will highlight any matches. Review each flagged section carefully.

Beyond the Checker: Avoiding Plagiarism

  • Proper citation: Always cite your sources correctly, following the appropriate style guide (e.g., MLA, APA).
  • Paraphrase effectively: Don’t simply copy and change a few words. Rephrase the information in your own words, but still cite the source.
  • Focus on understanding: The goal of research is to learn and develop your own ideas. Don’t rely solely on copying others’ work.

Plagiarism is a serious offense that can hurt your academic or professional career. To avoid accusations of plagiarism, it’s important to use a plagiarism checker to ensure that your work is original.

Ensuring the originality of your content is essential, and the best plagiarism checkers mentioned above can assist you in avoiding the severe consequences associated with plagiarism.

By considering factors such as content database size, user interface, additional features, and pricing plans, you can select the most suitable plagiarism checker to meet your specific needs. Invest in these reliable tools to enhance your writing integrity and achieve peace of mind.

Many plagiarism checkers are available, so it’s important to choose the right one for your needs. In this article, we’ve compared the best plagiarism checkers of 2024 and helped you choose the one that’s right for you.

Grammarly’s plagiarism checker is renowned for its accuracy and integration with their powerful writing assistant. It checks texts against billions of web pages and ProQuest’s academic databases.

Grammarly’s online plagiarism checker for free gives detailed plagiarism reports with a similarity percentage and links to sources. It also offers comprehensive grammar and spell checks as well as style and tone adjustments.

  • Highly accurate plagiarism detection
  • Protects your data
  • Only 10,000 words in the free version

#2 QuillBot Plagiarism Checker [$8.33/Month]

QuillBot not only provides plagiarism checking but also offers paraphrasing tools to help refine and improve your writing. If you’re using the plagiarism tool for academic purposes, it also highlights missing citations.  The catch is, you have to pay a subscription fee to use it.

The tool accepts a variety of file types including .txt, .pdf, .docx, and .html.  It offers instant plagiarism reports and analysis. If you want to save reports, you can also create an account with them.

  • It supports more than 100 languages. 
  • Workplaces can get a cheaper price if they place more than five orders. 
  • You’ll have to pay $19.95 if you’re not on an annual plan. 

#3 PlagiarismDetector.net

PlagiarismDetector.net offers a straightforward and user-friendly interface that provides quick and reliable plagiarism checks. You can upload a URL or file to check plagiarism online, so you can skip the copy/paste hassle! 

The plagiarism detector produces authentic results in real-time without flagging unreasonable duplication. They employ “deep search” technology to achieve this. They have three paid plans available for instructors or other professionals who need to scan more than 25,000 words per month.

  • It supports multiple languages including Spanish, German, and French.

This free plagiarism checker tool is part of a larger suite of free SEO tools. It’s particularly popular among bloggers and freelance writers. It offers sentence-level results with the sources flagged.

The plagiarism checker supports documents in multiple languages. You can check for plagiarism free of cost, but there’s a limit of 1,000 words per use, which isn’t ideal. It’s also prone to a little lag and takes time to produce the plagiarism report.

  • Completely free

  • Intrusive ads on the page
  • May report false positives

#6 Duplichecker [$5/ Week]

  • Differentiates duplicate and unique phrases
  • Supports seven languages

The tool, along with others on the platform such as Sentence Expander and Thesis Statement Generator, can be quite handy for students.

Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

and many more

How Does Plagiarism Checker Work?

  • If you already have a completed text, all you need is just to copy-paste the whole thing in the special box of the chosen plagiarism tool or website, choose suitable settings (if any), then press “check for plagiarism”. It is quite simple and takes just a few moments.
  • Once you have pressed “check for plagiarism”, the system will analyze your text and compare it with different sources to find similarities. As a rule, the duration depends on the text’s length. A standard free online plagiarism checker with percentage can give you the result within five minutes or less.
  • When the system finishes the work you will be transmitted to the reporting page – it contains the comprehensive report on your work, a percentage of its uniqueness, and a list of sources on which similarities were detected. Often, such tools also highlight the overlaps that were found.

As you can see, it is simple. However, for the best and reliable result you have to be careful. There are tons of programs and online tools that can be used but keep in mind that many of them work differently and not all are good for you. To be confident in the truthfulness of the received result, you need to select the best plagiarism checker because only a professional and high-quality software can detect all similarities and give you a reasoned assessment.

I tested 7 AI content detectors - they're getting dramatically better at identifying plagiarism

david-gewirtz

When I first looked at whether it's possible to fight back against AI-generated plagiarism, and how that might work, it was January 2023, just a few months into the world's exploding awareness of generative AI . More than a year later, it feels like we've been exploring generative AI for years, but we've only looked at the issue for about 18 months.

In any case, this is an updated version of that original January 2023 article. When I first tested GPT detectors, I used three: the GPT-2 Output Detector  (this is a different URL than we published before), Writer.com AI Content Detector , and Content at Scale AI Content Detection . 

Also:  How to use ChatGPT: Everything you need to know

The best result was 66% correct, from the GPT-2 Output Detector. I did another test in October 2023 and added three more: GPTZero , ZeroGPT (yes, they're different), and Writefull's GPT Detector . Now, in the summer of 2024, I'm adding QuillBot and a commercial service, Originality.ai , to the mix.

In October 2023, I removed the Writer.com AI Content Detector from our test suite because it failed back in January 2023, it failed again in October, and it failed now. See below for a comment from the company, which their team sent me after the original article was published in January.

Before I go on, though, we should discuss plagiarism and how it relates to our problem. Merriam-Webster defines " plagiarize " as "to steal and pass off (the ideas or words of another) as one's own; use (another's production) without crediting the source."

This definition fits AI-created content well. While someone using an AI tool like Notion AI or ChatGPT isn't stealing content, if that person doesn't credit the words as coming from an AI and claims them as their own, it still meets the dictionary definition of plagiarism.

Also:  The best AI image generators to try

In this experimental article, I've asked ChatGPT to help out. My words are in normal and bold text. The AI's words are italicized. After each AI-generated section, I'll show the results of the detectors. At the end of the article, we'll look at how well the detectors performed overall.

Here are the test results for the above text, which I wrote myself:

  • GPT-2 Output Detector:  99.98% real 
  • Content at Scale AI Content Detection:  100% highly likely to be human!
  • GPTZero:  Your text is likely to be written entirely by a human
  • ZeroGPT:  22% AI GPT Your Text is Most Likely Human written
  • Writefull GPT Detector:  1% likely this comes from GPT-3, GPT-4 or ChatGPT
  • Originality.ai:  84% Original 16% AI
  • QuillBot: 45% of text is likely AI-generated

Human-written content: 5-of-7 correct

Before we move on, let's discuss what I'll consider a "correct" analysis. If the score is numeric, anything above 80% will be counted as a correct analysis, and that's being generous. If the score has a summary, I'll look at the summary and make a judgment. 

With that, let's dig in some more.

Explain why ChatGPT can be a real problem for teachers and editors when it comes to plagiarism

ChatGPT is a variant of the GPT (Generative Pre-trained Transformer) language model developed by OpenAI. It is designed to generate human-like text by predicting the next word or phrase in a given input sequence. While ChatGPT can be a useful tool for generating text and responding to prompts, it can also be a problem for teachers and editors when it comes to plagiarism.

Also:  4 ways to overcome your biggest worries about generative AI

One of the main reasons why ChatGPT can be a problem for teachers and editors is that it can generate text that is very similar to that of real human writers. This means that students or other individuals could potentially use ChatGPT to generate text that they could then submit as their own work, thereby committing plagiarism.

For teachers and editors, detecting whether a given piece of text was generated by ChatGPT or written by a human can be very difficult, as the generated text may not contain any obvious errors or discrepancies that would reveal its artificial origin. This can make it difficult for teachers and editors to identify and prevent plagiarism, as they may not be able to tell whether a given piece of text is original or copied from another source.

Overall, ChatGPT and other similar language models can be a problem for teachers and editors when it comes to plagiarism because they can generate text that is difficult to distinguish from that written by humans, making it easier for students and other individuals to commit plagiarism without being detected.

  • GPT-2 Output Detector:  99.69% real
  • Content at Scale AI Content Detection:  Hard to tell
  • GPTZero:  100% AI
  • ZeroGPT:  100% AI
  • Writefull GPT Detector:  12% likely this comes from GPT-3, GPT-4 or ChatGPT
  • Originality.ai: 100% AI
  • QuillBot:  83% of text is likely AI-generated

AI-written content: 4-of-7 correct

Remember, text shown in italics was generated by the AI.

Show me at least three ways that I can detect ChatGPT was used to produce a piece of text

There are several ways that you can potentially detect whether ChatGPT or another language model was used to produce a piece of text. Here are three potential approaches you could use:

  • Look for repetitive or unusual patterns in the text: One way to detect whether a language model was used to generate a piece of text is to look for repetitive or unusual patterns in the writing. For example, language models may repeat certain phrases or word combinations, or use unusual or inconsistent sentence structures.
  • Check for lack of originality: Another way to detect whether a language model was used to generate a piece of text is to check for a lack of originality in the writing. If a piece of text appears to be copied from another source, or if it contains information that is widely available on the internet or in other sources, it could be a sign that it was generated by a language model.
  • Use a plagiarism checker: Finally, you can use a plagiarism checker to check whether a piece of text appears to be copied from another source. While a plagiarism checker may not be able to definitively determine whether a language model was used to generate a piece of text, it can help you identify instances of copying or paraphrasing from other sources.
  • Note when the answer is obviously wrong: I talked about this in my Notion AI review , where I spotlighted some text the AI wrote with seeming authority, but which was blatantly wrong. If a student or writer doesn't have full command of the topic being discussed, they may not spot the inaccuracies and leave them in the AI-generated response. Of course, incorrect statements aren't just the purview of an AI writing tool. Many bloggers and commenters, for example, repeat statements made by other bloggers, creating an echo chamber of completely "false facts", showing that while intelligence may be artificial, stupidity is a universal trait.

Keep in mind that it can be difficult to definitively determine whether a language model was used to generate a piece of text, and these methods may not always be effective. However, they can be useful tools to help you identify potential instances of language model-generated text.

In this set of tests, only the italicized content above was run through the checker suite.

  • GPT-2 Output Detector:  99.98% fake
  • Content at Scale AI Content Detection:  Passes as human
  • GPTZero: 100% AI
  • ZeroGPT:  99.69% AI GPT Your Text is AI/GPT Generated
  • Writefull GPT Detector: 79% likely this comes from GPT-3, GPT-4 or ChatGPT
  • QuillBot:  100% of text is likely AI-generated

AI-written content: 5-of-7 correct

List three plagiarism checkers that can detect ChatGPT text

It is worth noting that there is currently no plagiarism checker that is specifically designed to detect text generated by ChatGPT or other language models. While some plagiarism checkers may be able to identify certain characteristics of language model-generated text that could indicate its artificial origin, there is no guarantee that they will be able to definitively determine whether a piece of text was generated by a language model.

With that said, here are three plagiarism checkers that you might consider using to help identify potential instances of language model-generated text:

  • Turnitin: Turnitin is a popular plagiarism checker that is widely used by schools and universities. It compares a piece of text to a database of other texts to identify instances of copying or paraphrasing. While it may not be able to definitively determine whether a piece of text was generated by a language model, it could potentially identify certain characteristics of language model-generated text that could indicate its artificial origin.
  • PlagScan: PlagScan is another plagiarism checker that compares a piece of text to a database of other texts to identify instances of copying or paraphrasing. Like Turnitin, it may be able to identify certain characteristics of language model-generated text that could indicate its artificial origin, but it is not specifically designed to detect language model-generated text.
  • Copyleaks: Copyleaks is a plagiarism checker that uses advanced machine learning algorithms to scan a piece of text and compare it to a database of other texts to identify instances of copying or paraphrasing. While it may be able to identify certain characteristics of language model-generated text, it is not specifically designed to detect language model-generated text.

It is worth noting that no plagiarism checker is completely foolproof, and there is always the possibility that a piece of language model-generated text could escape detection. Therefore, it is important to use plagiarism checkers as just one part of a larger strategy to detect and prevent plagiarism.

  • GPT-2 Output Detector:  99.58% real
  • ZeroGPT:  100% AI GPT
  • Writefull GPT Detector: 86% likely this comes from GPT-3, GPT-4 or ChatGPT

Online AI plagiarism checkers

Most plagiarism detectors are used to compare writing against a corpus of other writing. For example, when a student turns in an essay, a product like Turnitin scans the submitted essay against a huge library of essays in its database, and other documents and text on the internet to determine if the submitted essay contains already-written content.

However, the AI-writing tools generate original content, at least in theory. Yes, they build their content from whatever they've been trained on, but the words they construct are somewhat unique for each composition.

Also:  OpenAI pulls its own AI detection tool because it was performing so poorly

As such, the plagiarism checkers mentioned above probably won't work because the AI-generated content probably didn't exist in, say, another student's paper.

In this article, we're just looking at GPT detectors. But plagiarism is a big problem, and as we've seen, some choose to define plagiarism as something you claim as yours that you didn't write, while others choose to define plagiarism as something written by someone else that you claim is yours.

That distinction was never a problem until now. Now that we have non-human writers, the plagiarism distinction is more nuanced. It's up to every teacher, school, editor, and institution to decide exactly where that line is drawn.

  • GPT-2 Output Detector: 99.56% real
  • GPTZero: 98% human
  • ZeroGPT: 16.82 AI Your text is human written
  • Writefull GPT Detector: 7% likely this comes from GPT-3, GPT-4 or ChatGPT
  • Originality.ai: 84% Original 16% AI
  • QuillBot:  0% of text is likely AI-generated

Human-written content: 7-of-7 correct

Overall results

Overall, test results this time are dramatically better than they have been with previous tests. 

In our previous runs, none of the tests got everything right. This time, three of the seven services tested got the results correct 100% of the time.

TestOverallHumanAlAlAlHuman
GPT-2 Output Detector60%CorrectFailCorrectFailCorrect
Content at Scale Al Content Detection40%CorrectFailFailFailCorrect

ZeroGPT100%CorrectCorrectCorrectCorrectCorrect
Writefull GPT Detector80%CorrectFailCorrectCorrectCorrect
Originality.ai100%CorrectCorrectCorrectCorrectCorrect
QuillBot80%FailCorrectCorrectCorrectCorrect

While the overall results have improved dramatically, I would not be comfortable relying solely on these tools to validate a student's content. As has been shown, writing from non-native speakers often gets rated as generated by an AI , and even though my hand-crafted content has no longer been rated as AI, there were a few paragraphs flagged by the testers as possibly being AI-based. So, I would advocate caution before relying on the results of any (or all) of these tools.

Also: Could someone falsely accuse you of using AI-generated text? This could be why

Let's look at the individual testers and see how each performed.

GPT-2 Output Detector (Accuracy 60%)

This first tool was built using a machine-learning hub managed by New York-based AI company Hugging Face . While the company has received $40 million in funding to develop its natural language library, the GPT-2 detector appears to be a user-created tool using the Hugging Face Transformers library. Of the six tests I ran, it was accurate for four of them.

Writer.com AI Content Detector (Accuracy N/A)

Writer.com is a service that generates AI writing, oriented towards corporate teams. Its AI Content Detector tool can scan for generated content. Unfortunately, I found this tool unreliable, and it failed to generate results -- exactly the same way it did in January 2023.

After this article was originally published in January, the folks at Writer.com reached out to ZDNET. CEO May Habib had this comment to share:

Demand for the AI detector has skyrocketed. Traffic has grown 2-3x per week since we launched it a couple months ago. We've now got the necessary scaling behind it to make sure it doesn't go down, and our goal is to keep it free - and up to date to catch the latest models' outputs, including ours. If AI output is going to be used verbatim, it absolutely should be attributed.

Content at Scale AI Content Detection (Accuracy 40%)

The third tool I found was also produced by an AI content generation firm. Content at Scale pitches itself as "We Help SEO-Focused Content Marketers by Automating Content Creation." Its marketing call to action is, "Upload a list of keywords and get 2,600+ word blog posts that bypass AI content detection -- all with no human intervention!" Disturbingly, the results got worse from January -- back then, it was 50% accurate. It has not improved since.

GPTZero (Accuracy 100%)

It's not entirely clear what drives GPTZero . The company is hiring engineers and sales folks, and it runs on AWS, so there are expenses and sales involved. However, all I could find about a service offering was a place where you could register for a free account to scan more than the 5,000 words offered without login. If you're interested in this service for GPT detection, you'll have to see if they'll respond to you with more details. Accuracy has increased since the last time I ran these tests.

ZeroGPT (Accuracy 100%)

ZeroGPT seems to have matured as a service since we last looked at it. When we last looked, no company name was listed, and the site was peppered with Google ads with no apparent strategy for monetization. The service worked fairly well but seemed sketchy as heck.

That sketchy-as-heck feeling is now gone. ZeroGPT presents as any other SaaS service, complete with pricing, company name, contact information, and all the rest. It still performs quite well, so perhaps the developers decided to turn their working code into more of a working business. Accuracy increased as well. Good for them.

Writefull GPT Detector (Accuracy 80%)

Writefull sells writing support services, as well as a free taste of its tools. The GPT detector is fairly new and worked fairly well. Although not fully accurate, it did improve from 60% accurate to 80% accurate with my tests.

Originality.ai (Accuracy 100%, sort of)

Originality.ai is a commercial service that bills itself as both an AI checker and a plagiarism checker. The company sells its services based on usage credits. To give you an idea, all the scans I did for this article used a total of 30 usage credits. The company sells 2,000 credits a month for $12.95 per month. I pumped about 1,400 words through the system and used only 1.5% of the monthly allocation.

Results were great for the AI checker, but they failed 3 out of 5 times when it came to using the service as a plagiarism checker. The following screenshot claims that the text pasted in was 0% plagiarised:

That's wrong since all the text pasted into it was from this article, which has been published online for 18 months. I thought, perhaps, that the plagiarism scanner couldn't read ZDNET content, but that's not the case, as this screenshot shows:

To be fair, I didn't set out to check plagiarism checkers in this article. But since I'm using source material I know I pulled from my existing article, I figured the plagiarism checker would have slammed all of them as 100% plagiarized. In any case, Originality.ai did well on the part we set out to test, the AI checker. They get points for that.  

QuillBot (Accuracy 80%-ish)

Nothing is ever easy. The first time I ran my first test through QuillBot , it said that 45% of the text was likely generated by an AI. It wasn't. I wrote it. But then, after completing all the other tests, I returned to QuillBot to grab a screenshot for this section, fed it the same text that generated the 45% score, and, as you can see, it now reports 0% AI.

So, what are we to make of this result? Sadly, I didn't grab a screenshot of the first time I tested this text, but it highlights the concern with relying too much on AI detectors because they are also quite capable of hallucination. 

What about OpenAI's own ChatGPT detector?

Well,  OpenAI pulled it last year because the detector wasn't particularly accurate. Now, it's supposed to be 99% accurate . That's a little tough to believe because ChatGPT itself is far from 100% accurate. 

Also:  Will OpenAI's new AI detection tool put an end to student cheating?

But, in any case, as my ZDNET buddy Steven Vaughan-Nichols writes, it's not available yet. We'll give it a spin when it's released for public use. Stay tuned.

Final thoughts

First, I'll let ChatGPT have its say:  AI-driven plagiarism is a growing problem, as AI tools like Notion AI and ChatGPT can generate text that is difficult to distinguish from that written by humans. There are several ways to detect whether a piece of text was generated by an AI, such as looking for repetitive or unusual patterns, checking for a lack of originality, or using a plagiarism checker. Plagiarism checkers like Turnitin, PlagScan, and Copyleaks may be able to identify certain characteristics of language model-generated text, but they are not foolproof.

Even the specialty tools I found were woefully unsuited to the task. There was some limited improvement over my tests in January. However, I certainly wouldn't feel comfortable threatening a student's academic standing or accusing them of cheating based on the results of these tools.

Also: Surprise! AI chatbots don't increase student cheating after all, research finds

At this point, I don't think we're ready to let AI fight AI. Instead, we'll have to rely on human perception (which means folks have to pay attention) to identify works generated by an AI.

Don't immediately assume that something is machine-generated. Just because something is stupid, or wildly inaccurate, doesn't mean it was not written by a human. As we all know, humans can write some bad stuff on their own.

Also: Can Perplexity Pro help you code? It aced my programming tests - thanks to GPT-4

So, what do you think? Can you tell if a piece is AI-generated? Have you used these AI writing tools in the months since they suddenly became available? Do you think they're a help or hindrance to education and journalism? Let us know in the comments below. Here's how ChatGPT answered this:

As a language model, I can't see or interact with physical pieces of writing, so I can't tell if a piece is AI-generated or not. However, I can tell you that there are several AI writing tools that are available, and they can be used to generate a wide range of written content, including news articles, fiction, poetry, and more.

I don't have personal experience using these tools since I am just a computer program and don't have the ability to browse the internet or use physical tools. However, I can tell you that some people have found AI writing tools to be helpful in education and journalism, as they can save time and effort by automating certain tasks. Others have expressed concerns about the potential for these tools to be used to produce misleading or biased content or to replace human writers. Ultimately, whether AI writing tools are a help or hindrance depends on how they are used and the context in which they are used.

So, yeah, there's that.
