5 Free Plagiarism Checker Tools for Students and Teachers

Plagiarism checker tools are one of the few things that students and teachers can both find useful.

Students can use these tools to make sure that their content is free from plagiarism before submitting it whereas teachers can use them to see whether the students have been doing any copying or not.

For both these scenarios, it is necessary for the teachers and students to use good-quality plagiarism checkers otherwise there’ll be no reliability in the checks.

But, finding the right tools can be a bit of a hassle.

So, how do you go about it? Well, you can start by reading this post till the end.

5 Free Plagiarism Checker Tools for Students and Teachers

1.      Plagiarism Checker by Prepostseo


Prepostseo is an online platform that has various utilities and tools for students, teachers, content creators, and so on. It has more than 95 different tools that are present in four different categories.

One of these categories is ‘Writing and Education’, and that is where you can find tools for teachers and students. And incidentally, that is also where you can find the plagiarism checker.

The plagiarism checker by Prepostseo is one of the most popular tools in the industry. It ranks among the top ten free online plagiarism checker tools, and for good reason too.

This tool can be used for free, and even by unregistered users. A lot of online tools can have an annoying mechanism where you paste or type in your content, and when you’re about to press the ‘Go’ button, you get hit by the ‘Please Sign Up’ prompt.

With Prepostseo, you don’t have to worry about any such problem. You can just load the page up, enter your text, run the check and then leave.

However, unregistered and free users do have to work with a tight input capacity. For these users, there is a word limit of 1,000 words per query.

Moving on, the plagiarism-checking process itself is very quick and accurate. The results are given out neatly in the shape and form of the original text. All the plagiarized parts of the text are underlined in red. Since this tool runs on an AI-powered algorithm, it can also spot those sentences that have been rephrased or paraphrased lightly. These types of lines are shown in orange.

The exact sources of the copied content are given on the right side of the results. Here, there is another feature that students and teachers can find helpful. And that is the report generation.

By clicking on the ‘Download Report’ button, you can download a detailed document (in HTML or PDF format) that contains information about the test as well as the percentage of uniqueness and duplication in the content. The matched sources are also given in this report.

Students can attach the report with their submissions as proof, whereas teachers can use it to give detailed feedback to the students about the plagiarized parts in their work.

2.      Check-Plagiarism


Check-Plagiarism.com is also a popular name among online plagiarism checkers. It can be used for free, and it does not require an account to start.

Check-Plagiarism is, like Prepostseo, a freemium tool…which basically means that it has a free version as well as a paid one.

In the free version, users can enter up to 2,000 words in a single query. This is quite a generous limit, considering that other tools usually only let you enter 1,000 words on a free plan.

Other than that, free users have to deal with a lot of ads around the interface as well as a captcha before running the process.

On the other hand, by subscribing to the paid version, you can increase the word limit up to 20K words in a single go. You can also get rid of the captcha and the excessive number of ads.

The working of the tool itself is quick and accurate. The results are given out as a sentence-wise report that clearly highlights which sentences in the given text were plagiarized and which were original. This tool also lets you download the report in the standard PDF format.

3.       Plagiarism remover


Contrary to what the name of this website may imply, Plagiarismremover.net does not only have a plagiarism remover tool. It also has a plagiarism checker, as well as other various content optimization utilities. However, we’re just going to be looking at the former for now.

One of the main things that we liked about the plagiarism checker by Plagiarismremover.net was how quick and seamless it worked. There is no captcha required, and the process itself is remarkably fast.

On the plagiarism checker tool page, you get an input box right in the middle of the screen where you can enter your content. You can also upload a file from your device (or import it from Drive or Dropbox) by clicking on the ‘Choose File’ button at the side of the box.

Once the content is imported, all you need to do is click on the ‘Check Plagiarism’ button. The process will start, and the results will be given out right below the input box.

Like Check-Plagiarism.com, this tool also gives you a sentence breakdown of the entered text. All the plagiarized sentences have the words ‘Plagiarized’ written alongside them in dark blue whereas all unique sentences have the word ‘Unique’ written alongside in a light blue color.

4.      PLText

PlText is yet another excellent plagiarism checker that comes with a clean and simple interface. It’s easy to use, and the results provided by it are accurate as well. It’s free and it can be used without any sort of registration.

To import your content, you can paste or type the text directly in the box. There are no options to upload files directly from your storage or from any other cloud service.

When you type or paste your content inside the input section, you will be able to see the total number of characters, words, and sentences given along the bottom border. This is something we think can be a great help to students,

After that, you can go ahead and click on the ‘Check Plagiarism’ button to start the process. The process does take some time to complete.


Once the results are out, you can see all the duplicated parts of the text underlined in red and all the unique parts underlined in green. A brief and general outline of the matched sources and the percentage of duplication from each one will be shown in a box on the right of the output section.

By clicking on the button at the top right corner of the output box, you can also click on the ‘List All Matches’ option to see a sentence-by-sentence breakdown of the plagiarism report.

5.       Plagiarism Checker by Softo


Softo.org is an online platform that hosts a lot of different tools related to content optimization and SEO. Their plagiarism checker is a good tool to use for finding duplication in all types of content. For one, it’s free to use and it does not require any sort of registration.

And unlike some of the tools that we’ve discussed until now, Softo.org does not have an option for signing up or creating an account. In other words, all of its tools are fully available to all and sundry without any sort of reservations.

Coming back to the tool itself, the plagiarism checker by Softo.org has a very clean and simple interface that users can get around without getting confused a lot. There is a simple input section where the text can be directly typed or pasted. There is also an option for direct file uploads.

After you’ve imported your content to the tool (using any of the methods mentioned above), you can go ahead and run the captcha. And once the captcha is complete, you can click on the ‘Check Plagiarism’ button to start the process.

The results given by this tool are similar to those given by Check-Plagiairsm.com in that they are given sentence-by-sentence.


For students, checking plagiarism is something that has to be done on almost a daily basis. They have to regularly submit assignments and papers; all of which have to be free from duplication.

Similarly, teachers have to use plagiarism checkers quite often to make sure that the work submitted by their students is unique and original.

In this post, we looked at five different online plagiarism checkers that students and teachers can use in 2022. All of these are free to start, and some of them have the option of registering as well.
