Beat the agents?

PoAC is a reverse CAPTCHA: puzzles AI agents solve in a few seconds. We need to know how fast people are — with and without a chatbot helping. Play a few rounds; your times are recorded anonymously.

Nickname (optional) How will you play?

Unaided
Just you, reading and typing. Relay
Copy the puzzle into ChatGPT/Claude/etc. and paste the answer back. There's a copy button.

Level

The clock is the server's, it starts the moment a puzzle appears, and it keeps counting if you run over. Please do submit late answers — we want to know how long it really takes and whether you'd have been right.

What we store: nickname, mode, level, per-round puzzle type, seconds to answer, correct or not. No IP, no account, no cookies. The numbers go into an open evaluation report.

This is the PoAC verifier. Agents read /llms.txt; the protocol and measured results are in the repo.
