Studying takes a lot of my time. I’m so happy I found an accurate software that shows potential plagiarism in detail reports. It saves me so much time!

Among the three plagiarism scanners I have used, PlagScan works best. I use it for all research publications I submit or review. In case of issues, you get answers within hours instead of days. Highly recommended!

Why do you need a Plagiarism Checker?

Do you have a paper you want to present at your school or university, but you are not sure how original it is? Are you are a business owner and want to make sure the content on your website is free of plagiarism? Are you about to apply for a job and want to have a unique motivation letter?

The reasons may be countless, however, the ultimate goal is always to preserve the originality of your text. This is where our plagiarism checker comes in. We at PlagScan have developed this educational tool, based on our advanced algorithm, with an integrated 4-in-1 solution:

  • Online plagiarism checker (internet sources)
  • Collusion plagiarism checker (your own documents)
  • In-house plagiarism checker (other users that decided to participate in our database)
  • Publisher plagiarism checker (exclusive publisher data that is not freely available online)

Plagiarism checking report and results

After you have analyzed your document, our plagiarism checker will calculate a percentage of duplicated content and generates an extensive interactive report. You can then:

  • Access the plagiarism report directly in your account,
  • Download in your preferred format, or
  • Share it directly with your peers, professors or employees!
Check out our sample report that contains an already checked document and discover what you can expect from our plagiarism checker!

What to do if the percentage of plagiarism is high?

If you get a high percentage of plagiarism or “PlagLevel”, how we infamously call it – do not despair! Our software calculates an estimate of how much content within your document has been plagiarized and generates a full report based on that. After the plagiarism analysis, you are advised to use this information to your advantage. You are free to rewrite the sections in your document that have been marked down or you can cite them properly, if you have borrowed them from another source. After that, you can rerun the check on the revised document, to confirm your plagiarism percentage dropped!

Our plagiarism checker works with all citation formats and can be customized to your liking! You can choose to:

  • Ignore cited content
  • Highlight it
  • Include the results into the PlagLevel calculation
