FAQ
Questions, answered.
How does the detector work?
It measures things that differ between typical AI text and typical human writing: how much sentence length varies, how often the same sentence openings repeat, stock phrases that language models overuse, contractions, and personal or informal touches. It runs entirely in your browser.
How reliable is the result?
Treat it as a hint. No detector — including paid ones — can prove who wrote a text. Formal human writing can look “AI-like”, and edited AI text can look human. Never use the score alone to accuse someone.
How much text do I need?
At least five sentences; 150 words or more gives a steadier reading. Short texts are reported as inconclusive.
