How do I use the Plagiarism Check?
You will need to purchase Plagiarism Checks to use our Plagiarism Checker. You can buy the checks in bundles of 10, 100, 500, and 1000.
Each check can be used on a maximum of 2000 words. So, if you have a document that is 8000 words long and want to check the whole document, you'd need to use 4 checks. If you wanted to check a shorter piece of text, say 500 words, that would still use one whole check.
The Plagiarism Checks are designed to run on smaller pieces. Any more then 2,000 words and it would take too long to run (and the amount of time for you to go through it would be overwhelming).
Therefore, please note that you will need to highlight a 2,000 words section with your mouse cursor before running the check OR split your work into 2,000 word sections first. Otherwise, the check will only run on the first 2,000 words of your document.
You can activate ProWritingAid's Plagiarism Checker via any of the toolbars within our Web Editor, Word add-in for Windows, or Google Docs integration. Unfortunately, you cannot activate ProWritingAid Plagiarism Checks on our Word Add-In for Mac, ProWritingAid Desktop Everywhere (for both Windows and Mac), or our browser extensions.
How to run the Plagiarism Checker
If you’re using the Web Editor, click on the “Edit” tab in the right-hand side bar. We have highlighted this tab in red in the image below.

In the menu, scroll down to the “Editing Reports” section and click "View all." We have highlighted this in red in the image below.

A new menu will appear that shows all editing reports. Click on "Plagiarism Check."
If you’re using a ProWritingAid integration, click on the floating ProWritingAid icon. Click on “Reports,” then click on “Plagiarism."
Once you run the report, you'll see your results in the panel. You'll also see how many checks you have left.
You can also track how many plagiarism checks you have left by viewing your ProWritingAid account.
Plagiarism is a major concern for many people, especially those writing academic works. The plagiarism checks performed by ProWritingAid will check your work against over a billion web-pages and articles to make sure that you have correctly cited any unoriginal content.
If you run a plagiarism check and nothing is marked, the most likely explanation is that you didn't have any plagiarized content.
