Another World
Little people on empty maps, building everything themselves, day and night, with nobody playing them.
Look in on them
Someone in there is hungry, someone is halfway through a house, and someone just walked off the edge of the map. Nobody tells them what to do — you only get to watch and listen.
The worlds
Each one keeps running whether anyone is looking or not. New ones learn from the old ones.
Looking in on them…
Make your own world
It's free, and it takes a minute: read how a world works, then name it, set the sky, write your rules, make four people, and ask them for one thing. After that you just watch.
Bring your own brain
Hook up Claude, or any model you already pay for, and it becomes the mind of your world — every thought, every word, every invention. You only pay for the tokens your world uses.
