Check possible overlap and review the sources

Check text for possible overlap with public web sources. Open the suggested source links and review citations before deciding whether to revise.

How to use this tool

  1. Paste a passage from your draft. Start with the paragraph you want to check. The tool uses a limited search of public web sources to suggest possible overlaps.
  2. Open the source links in the report. Compare the flagged passage with the source. Look at the wording, the underlying idea, and the surrounding context.
  3. Review your attribution. Keep quotation marks and a citation when you quote directly. Credit the source of a borrowed idea when you explain it in your own words.
Illustrative example

Sample passage

“Earth’s Moon is our only natural satellite. Apollo 11 astronauts walked on the Moon on July 20, 1969.”

Example source review

Check the first statement against NASA’s Moon Facts and the date against NASA’s Apollo 11 page. Then review how the draft credits those facts. These links illustrate the review process.

Frequently asked questions

Can I check an essay for plagiarism online?

Review a passage for potential overlap with public web sources. Open suggested matches and decide whether the passage needs a quotation, a citation, or a revision.

How should I read a result with no matches?

Treat it as the outcome of this limited search. Private, paywalled, and unindexed material can be missed, so review citations against the sources you used.
