Plagiarism checker for students

Plagiarism is often accidental: a note copied while researching, a quote that lost its quotation marks, a paraphrase that stayed too close to the original. Running your draft through a plagiarism checker before you submit it lets you find and fix those passages yourself.

How to check your draft

Finish your draft, including quotations and citations.
Paste the text into the free plagiarism checker and press the check button.
Look at each passage that is flagged and open the page it matched.

Fixing a flagged passage

It is a quotation you meant to quote: add quotation marks and a citation if either is missing.
It is your own wording of someone else's idea: rewrite it in your own words and structure, and cite the source.
It is a common phrase or a name: no change needed.
You cannot say where it came from: find the source and cite it, or remove the passage.

Good habits

Keep notes that mark clearly which text is a direct quote and which is your own summary. Write the source next to every note as you take it. Check your draft early, not at the deadline.

The checker searches the public web, so it will not catch everything. A clean report does not guarantee that a teacher's own tools will find nothing. See how plagiarism checkers work for what a report can and cannot show.
