Check a draft before you submit
Detectors such as GPTZero, Turnitin, and ZeroGPT estimate whether a draft looks AI-written. They can also flag human writing.
SupWriter includes an AI detector so you can check a draft before you submit. It is a pre-check based on one scoring model, not the detector your school or client uses. Results vary by detector, text length and topic, and no tool can guarantee a result. How we test AI detectors





Use the built-in AI detector (free on paid plans) to review a draft before you submit. A score is an estimate, not a guarantee.
