That one website that guesses whether text was written by AI (not reliably)

Why it's the pick

Paste up to 10,000 characters with no account and it highlights the sentences that look machine-written. Treat the score as a hint, not proof: every AI detector gets things wrong, especially on short, edited or non-native-English writing, so never accuse anyone based on one.
