Plagiarism checker
Paste your writing and the source text you used (an article, notes or another essay). The checker finds shared word sequences, highlights them and gives a similarity score so you can rewrite or cite before you submit.
Private: the check runs only in your browser and nothing is uploaded. It compares against the sources you paste, not the whole internet.
Frequently asked questions
Does this search the whole internet?
No. It compares your text with the sources you paste, which is the most reliable way to check your own paraphrasing. Nothing is uploaded: the comparison runs entirely in your browser.
What similarity score is acceptable?
Many schools consider under 10–15% fine when quotes are properly cited. Any highlighted phrase you did not put in quotation marks with a citation should be rewritten or cited.
How do I fix matches?
Either put the exact words in quotation marks and add a citation, or rewrite the idea in your own words and sentence structure and still cite the source.
