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.
Is there a minimum amount of text needed for an accurate score?
Yes, very short snippets are harder to score reliably; a paragraph or more gives a more accurate result.
Is AI detection ever wrong?
Yes, no detector is 100% accurate — treat the score as a strong signal rather than definitive proof.
Is this AI detector free to use?
Yes, it's free with no signup, though heavy repeated use may be rate-limited.
Does it work on any type of writing, like essays or emails?
Yes, it analyzes any block of text, from essays and articles to emails and social posts.
