Frequently Asked Questions
How accurate is it?
Accuracy depends on the detection service’s database and on how much of your text matches. No checker is perfect, so always read the flagged passages yourself instead of trusting a single score.
Is my text stored?
Your text is sent to the connected detection service for the check itself. It is not published anywhere, and you should not paste confidential or unpublished material into any online checker.
Is there a word limit?
The live tool will show its word limit before you run a check. Limits exist because each check uses the detection service, so very long documents may need to be checked in sections.
Tips
Quote short passages properly and cite the source instead of copying them. After a check, rewrite flagged passages in your own structure, not just by swapping a few words, and run the check again. Remember this tool runs through a connected detection service on the live site, and no score replaces your own judgement.
