Free AI detector, sentence by sentence
The AI detector estimates how much of a piece of writing reads like it was produced by an AI tool such as ChatGPT. Each sentence is shaded by how likely it is to be AI-written, so you can see exactly which parts sound robotic and revise them in your own voice.

Questions
How accurate is it?
No AI detector is perfect, ours included. Formal, technical or very short writing can be flagged by mistake. Treat the result as a guide for revising, never as proof of who wrote something.
Can I use it to accuse someone of cheating?
Please don't. Detector scores are estimates and can be wrong. Use them to start a conversation, not to decide one.
