How much of this was written by a person?

Paste a document or upload a file. HumanScore estimates what share was written by a human and what share by AI, and highlights which passages are which — with the reason for each call.

An estimate, not proof. No detector can reliably tell who wrote a sentence, and fluent human writing gets flagged sometimes. Use a result as a reason to look closer, never as grounds for an accusation on its own.

Private test — access is limited to invited accounts for now.
