Instantly play, create and remix interactive mini-apps
A constantly updated feed of trending creations, top creators and curated categories such as meme, relax, strategy, action and puzzle.
A studio that lets you build a playable mini-app, then publish it to the community in minutes.
Take any published creation, change it and re-release your version — the engine behind most of the catalogue.
Everything runs in the browser with no install, and the same creations work on iPhone and Android through the Sekai app.

An AI narrator co-writes your ridiculous adventure
Each session is generated fresh by a GPT-powered narrator based on your decisions, so no two adventures repeat.
Injuries persist and death is possible, and in-game goals track your progress, giving choices real weight.
Play on web, mobile or desktop, online or offline, with adventures syncing across devices.
Bring your own API key for the narrator model, or run it locally, for control over cost and privacy.
