Why we recommend it
Every other detector in this category wants an account, a credit balance, or both, and none of them tell you what they measured. This one runs entirely client-side, shows which signals pushed the score and by how much, and publishes its own measured false-positive rate instead of selling a number as proof.
Strengths
- Free with no sign-up and no usage limit. Nothing is uploaded — the model runs on your device, which you can verify in the network tab. Shows which signals pushed the score and by how much, scores each sentence separately, and states its measured accuracy and false-positive rate on the page.
Keep in mind
- About 85% accurate on unseen generators, so roughly one human passage in eight is wrongly flagged — worst on formal, technical and second-language writing. English only, and unreliable under 120 words. A reading aid, not evidence.
