Using the Plagiarism Checker

Have more questions? Submit a request

The Jasper Plagiarism Checker is powered by Copyscape, the world's most advanced plagiarism detection system used by millions worldwide. It makes it easy to check if any of the text in a document has been used anywhere else online.

How to run a plagiarism check

  1. Inside of your Document, click "Tools" in the top right corner.
  2. Add credits to your account if you don't have any available.
  3. Choose the text you want to check: 
    1. To check all the text in a document, click Scan document.
    2. To limit the plagiarism check to a smaller section, highlight a section of text and click Scan selected text.
  4. If text is found elsewhere, you'll see the text and site appear in a dropdown. You can visit that site through the provided links.
  5. If you choose, you can then edit the text of your document to remove any sentences found on other sites.


Plagiarism checks are an optional add-on to any plan.

Searches cost $.03 for the first 200 words plus $.01 for each additional 100 words. Plagiarism check credits can be added to your account, starting at $10.


Why do I need a plagiarism check? I thought Jasper didn't plagiarize?

As discussed in this course, it is highly unlikely that Jasper will write text written elsewhere. However, it does occasionally happen, and many of our users find value and peace of mind in running text through a plagiarism checker after completing a document.

Additionally, many users paste in content from other sites as a starter and want to be sure none of that original content is leftover at the end.

Do unused credits ever expire?

Unused credits expire after 1 year. If you need that extended, just email us at, and we'll help you out.

Is there a maximum amount of words I can scan at a time?

We recommend you limit your checks to under 3,000 words at a time. You can check up to 50,000 words in one run, but the quality slightly decreases as you check more words.

When I see matches in a search, does that mean my content has been plagiarized?

Our plagiarism checker, powered by Copyscape, finds similar content online but does not make judgments about which page is the "original" or whether content has been copied from another page. When a match is found, it could be that: one page has copied from another, that one page is legitimately quoting another, that both pages are quoting from the same external source, or that similar phrases happen to appear on both pages by chance. It is up to the user to sift through each case and determine the nature of the similarity found. Please see Copyscape's Guide to Online Plagiarism for further information on identifying and responding to website plagiarism.

What should I do if someone has stolen my content?

In defending your rights online against plagiarists, it's important to be both vigilant and proactive. Copyscape's Guide to Online Plagiarism includes basic easy steps you can take to prevent and respond to website plagiarism.

How can I tell the plagiarism check to skip parts of my document?

You may instruct Copyscape to refrain from checking for copies of certain parts of your web page. This is done by adding a  <!--copyscapeskip--> tag at the beginning of the section you want to be excluded and adding a <!--copyscapeskip--> tag at the end of that section. Note: This skipping works in one direction only – it will not prevent Copyscape from finding this content on your page when searching for copies of other pages.

Where does the plagiarism check get its results?

Copyscape uses Google and Bing as search providers under agreed terms. Search providers send standard search results to Copyscape without any post-processing. Copyscape uses complex proprietary algorithms to modify these search results in order to provide a plagiarism checking service. Any charges are for Copyscape's value-added services, not for the provision of search results by the search providers.
