This article will help you find the right tool for your needs by describing some tools along with their features and benefits.

Best Plagiarism Checking Tools in 2023

Below we have discussed the three best plagiarism checking tools along with their key feature, pros, and cons.

1.     Copyscape

On top of the list, I have Copyscape – one of the most popular plagiarism detection tools in 2023. This tool makes use of a diverse set of algorithms that efficiently compares the given text with all the internet resources like blogs, research papers, e-books, journals, etc.

While comparing, if any trace of plagiarism is found, the tool will highlight the plagiarized part with a red line along with the matched source. So that, users can easily figure out which part of their text is copied.

One of the best things is that it provides a special “Compare text” option. With this feature, users can compare the plagiarized text with its matched source on the spot. For a demonstration of this, I have attached an image below, check it out:


One more useful feature of Copyscape is that it can check plagiarism in all languages (that use common alphabets). However, it is important to note that, it is completely a paid tool, and offers nothing to free users.

Key features:

  • AI-powered plagiarism detection
  • Multilingual support
  • Special Compare text feature


  • Intuitive user-interface
  • Fast and accurate
  • Safe and secure


  • Not available for free

2.     Turnitin

Turnitin is another useful plagiarism-checking tool that is specially designed for students and educational institutions. It allows users to efficiently scan their written work for any kind of plagiarism. This tool works by comparing text with online sources and then highlighting similar content with blue color along with an overall similarity score.

Not just this, but it also flags the completely plagiarized parts with red lines, so that users can take care of them as a priority. Apart from this, it also shows the percentage of how much text is copied from a particular source.

In general words, Turnitin shows useful insights into deliberate text manipulation, for a demonstration of this, check out the picture below:


So, as you can see in the image above, the plagiarism-checking tool provides both the percentage and overall similarity. Apart from this, it also several other useful insights that can be beneficial for the user.

Moreover, the tool offers a special “Translate Matching” feature. This feature allows users to submit their content for plagiarism detection in different languages. It supports 54 international languages for plagiarism detection purposes.

However, one downside of this tool is that its insights may not be easily understandable for every user, especially students. Additionally, it is not available for free users and its paid plan is also expensive, suitable for organizations or institutions.

Overall, Turnitin is a reliable plagiarism-checking tool that is being used by popular educational institutes and students all around the globe.

  • Quick and accurate plagiarism detection
  • Overall similarity score
  • Flag plagiarized parts with different colors

3.     Plagiarism Checker by Editpad

Last, but not least, we have another useful plagiarism-checking tool by EditPad. It is a freemium tool that uses a diverse set of algorithms that efficiently compare the given text with millions of online resources to find plagiarism.

The tool then provides a detailed plagiarism scan report that includes the percentage of both unique and plagiarized content, matched sources, the total number of unique words, etc. Not only this, but the tool also provides an overall similarity score of the input text.

To explain better how this tool works, we have copied some text from an online article and checked its plagiarism using this tool. The output we got is in the image below:


So, the tool has accurately captured the input text as completely plagiarized. Sentences underlined with red lines show exact match plagiarism. On the other hand, sentences that are underlined with yellow lines indicate Paraphrased plagiarism.

This plagiarism checker is available in both free and paid versions, with free users can check up to 1000 words at once while premium users can check up to 3,000 words.

Moreover, the tool supports 14 different languages including English, Espanol, Russian, and many more.

The market is overloaded with too many detection tools, making it difficult for users to pick a reliable one. In this article, we have discussed the top three plagiarism-checking tools along with their detailed working, key features, pros, and cons. So that you can pick the one that you think is suitable.
