About the detector
What does the score mean?
The headline percentage estimates how likely the text is AI-generated. We pair it with a confidence level and sentence-level highlighting so you can see the evidence, not just a number.
Which file types can I check?
You can paste text directly or upload common document formats. Long documents are analyzed in full with per-section results.
How is this different from a plagiarism checker?
Plagiarism tools compare your text against existing sources. An AI detector estimates whether text was machine-generated - a different question.
Detect AI with confidence - in any language
