Frequently asked questions

How does the AI detector decide if text is AI-generated?

The AI analyzes writing patterns, phrasing, and sentence structure across the text and scores how closely it resembles typical AI-generated writing versus human writing.

Can it tell me which sentences look AI-written?

Yes. Alongside the overall score, it highlights the specific sentences that read as most likely AI-generated so you can see exactly where they are.
