AI detectors: why they cannot reliably tell who wrote something

Many tools claim they can detect AI-written text. In practice they are unreliable, and some students and writers have been wrongly accused because of them.

Why they struggle

• They guess based on patterns, and humans can write in predictable patterns too
• Simple, clear writing by non-native speakers is often flagged
• Light editing of AI text can fool them

What this means for you

Do not treat a detector score as proof. Teachers and editors get better results from drafts, version history and simply talking to the writer about their work.
