About Detectize

Detectize is a free AI detector built for students and writers who want to know how their work looks to an AI checker before they hand it in.

AI detectors used by schools are not perfect. They can flag writing that a person produced entirely on their own – especially formal, polished or non-native English. We think you deserve to see the same kind of signal first, sentence by sentence, so you can review and revise with confidence.

Detectize is an independent tool and is not affiliated with, endorsed by, or sponsored by Grammarly, Turnitin, GPTZero, Scribbr, Copyleaks or any other company mentioned. All trademarks belong to their respective owners. AI detection is probabilistic: no detector, including ours, can prove whether a text was written by AI.
