OrigoZero is a platform for making 3D games and worlds with AI and playing them in the browser. Describe a game at origozero.ai/create, and the site's agent builds it in Zero, a real-time 3D engine that runs in a browser tab. ZeroMind is the service behind it: it stores every world, keeps its history, and lets any published part of any world be found and installed in another.
Games built here are programs, not generated video. The agent writes Luau, places entities, runs the world and looks at screenshots of what happened. You can keep editing, by chat or by hand, and publish to a page anyone can open and play.

- Play what people have built: every public world runs in a browser tab.
