Plagiarism Checker

Compare two texts for similarity — shared vocabulary, phrasing overlap and matching passages.

  1. Paste the first text
  2. Paste the second text
  3. Compare and review the overlaps

Compares only the two texts you provide — it does not search the web.

Frequently asked questions

Does this check against the internet or a database of papers?
No — it only compares the two texts you paste in against each other, looking at shared vocabulary, phrasing overlap and matching passages. It does not search the web or any external database.
What counts as a "match" between the two texts?
Overlapping word sequences and repeated phrasing between the two passages are highlighted, giving you a similarity picture rather than a legal plagiarism verdict.
Can I use this to check a student essay against a source?
Yes — paste the essay in one box and the suspected source in the other to see how much wording overlaps, though for institutional plagiarism checks you should also use your school’s dedicated database-backed tool.
Are my texts uploaded or stored anywhere?
No. The comparison runs entirely in your browser — nothing you paste is sent to a server or kept.
Do I need to install anything or sign up?
No. It runs entirely in your browser — no software install, no account, no email required.
