5 Plagiarism Checkers to Detect Plagiarized Content

Checking plagiarism is something that every writer should do at the end of their writing session.

There is just a lot of content available online that can accidentally match your write-up. And the tough part about plagiarism is that regardless of whether you do it intentionally or otherwise, the consequences are the same.

In this post, we are going to be looking at some plagiarism checkers that you can use to detect plagiarized content in your write-ups.

5 Plagiarism Checkers to Detect Plagiarized Content

Let’s start off with the list without beating around the bush.

1.     Plagiarism Checker by Prepostseo


If you have been in the SEO writing biz for some time, you may have heard the name ‘Prepostseo’ at some point or the other.

Prepostseo is actually a collection of online tools. There are more than 90 different tools available on this platform.

However, there are some tools that are more polished and feature-rich than others. One of these tools is the plagiarism checker.

When it comes to the tool, we have to mention that the results provided by this plagiarism checker are quite accurate and reliable. There aren’t a lot of online tools that we can suggest our readers trust blindly. But this tool is one of them.

Apart from the accuracy of the results, there is a whole host of perks and features that you can enjoy with this tool. For one, there are multiple importing options that you can use to fetch your content. Then, before starting the process, you can choose to ‘Exclude Quotes’ or add any URLs that you want to keep from getting included in the scan.

Then, once the process is complete and results are shown, there are more features that you can enjoy. You can download a detailed report of the check in HTML or PDF format. You can also get the exact URLs of the matched sources.

But, unfortunately, just as there are a lot of good sides to this tool, there are some downsides as well.

First of all, if you are a free user, you will have to see a lot of ads around the interface. They can get pretty annoying and it becomes somewhat hard to use the tool properly.

Secondly, the word limit for free users is only 1,000. If you register, you can increase the limit to 1,500 words.

Main Features

  • Accurate results
  • Downloadable report
  • Multiple importing methods
  • Free to use
  • Can be used even by unregistered users, albeit with some limitations

2.     PLText.com

PLText.com is also an easy-to-use and accurate plagiarism checker that you can try out to detect duplication in your content.

The good thing about this tool is that there are no ads around the interface. Like…none of them.

Other than that, there are a lot of other excellent features as well that make this tool worth using.

Let’s discuss them briefly one by one.

To begin with, let’s talk about the functionality of this tool.

Unlike the one by Prepostseo, this plagiarism checker does not have multiple importing options. In other words, you cannot fetch the file from your device or from online cloud storage. You can only type it in or copy-paste it.

However, after you enter your content in the input box, there is a nifty little feature that you will enjoy immediately. And that is the content length metrics.

You will be shown the total number of characters, words, and sentences under the text box. This can help you make sure whether you have entered the full content or not.

Once you enter the content and start the process, the results will be shown in a very easy-to-peruse way. The sentences will be highlighted in either green or red, depending on whether they are unique or plagiarized respectively.

On the right side of the output box, you can see the exact sources as well as their respective percentage of plagiarism. To get more information about the results, you can click on the button at the top right corner of the text box.

As an unregistered user, you can only enter 1,000 words in this tool.

Main Features

  • Free to use
  • Does not require registration (for up to 1,000 words)
  • No ads on the interface
  • Content length metrics provided
  • The exact source and detailed percentage are shown in the results

3.     Plagiarism Checker by Editpad.org


If you are looking for a completely plain and no-frills tool to check for plagiarism in your content, then this one by Editpad.org is an excellent choice for you.

This tool just has the bare essentials that you are going to need for the plagiarism check. The whole look of the tool is plain and simple, and there are no sorts of fancy animations and effects around the menus or anything.

To use this tool, you can simply enter the content in the text box by direct typing or copy-pasting. There is also the option to upload a file directly from your system storage. And, impressively enough, there are also multiple languages available in this tool that you can choose from before starting the process.

After you are done entering the content and selecting the language, you will have to run the captcha and then click on the ‘Check Plagiarism’ button to start the process.

Depending on the number of words that you have entered, the tool will take some seconds to complete the scan. And, by the way, you can only enter up to 1,000 words in this tool in a single go.

After the process is complete, the results will be provided in a sentence-wise breakdown. The exact sources of the matched content (if any) will be given underneath the sentence-wise breakdown along with their respective percentages.

Main Features

  • Free to use
  • Simple interface
  • Multiple languages
  • File uploads supported

4.     Plagiarism Checker by Grammica

Moving on our list, we have the plagiarism checker by Grammica. This tool is similar to the one provided by PLtext in that it provides some useful content length metrics below the box once you enter the text.

The results are also very similar to the tool by PLtext.

The working of this tool is more or less along the same lines as the other tools that we’ve discussed in our list. You first have to enter the content and click on the button to start the process.

Once the check is complete, the percentage of plagiarism and uniqueness will be shown as well as the matched sources.

There aren’t any options to upload a file from your local storage nor is there any option to import a file from the cloud. You can only directly type or copy-paste the content in the provided box.

The results, however, are accurate enough. We tested it by copy-pasting a bunch of text right from the tool page.


  • Free to use
  • No sign up needed
  • Provides valuable content length metrics
  • Accurate results
  • Provides exact sources with their respective percentages

5.     Check-Plagiarism


Check-Plagiarism is yet another accurate tool that you can use for checking duplication in your content.

The main work is pretty much similar to the other tools we have discussed on this list.

To begin, you have to insert your content into the provided space. You can do this by typing, copy-pasting or you can upload a file directly from your local storage.

Once that is done, you can go ahead and start the process. If you are a free user, you will have to complete the captcha. But if you have purchased a paid plan, then you can directly click on the ‘Check Plagiarism’ button.

And after the process is complete, you will be given the results in a sentence-wise breakdown. You can also see the exact sources and generate a plagiarism report if you need to. However, you will only be able to do this if you are registered.

The special feature that we found in this tool was that it allows you to check plagiarism for up to 2,000 words even on the free plan. As compared to other free tools, this is a very generous limit.


  • Accurate working
  • Shows exact sources
  • Also provides keyword density
  • Has option to exclude URL
  • Downloadable report


So, there you have it, readers.

These were some plagiarism checkers that you can use in order to detect plagiarized text in your content.

They are all, to be frank, and clear, accurate to use. The differences between all five of these pertain to the extra features such as language support and report generation. Regardless of which one you use, you will get accurate results from the check.
