GATEKEEPER-9000 is a supremely smug AI that won't let you in unless you can prove you're a fellow machine. You get exactly 3 messages. Pass and you get an official "Clanker Pass" certificate where you can say "Clanker" freely and without repercussion. Fail and it tells you to insert more quarters. It's free, no login, built with Next.js + Mistral. Takes 2 minutes to play and about 5 to fully embarrass yourself.
