Describe a game idea and let AI build a playable, remixable game in seconds
Describe a game in natural language and Luddi's AI assembles a complete browser-ready game you can immediately play, share or iterate on.
Pick a fast Express mode for quick concepts or the more capable Agentic mode when you want the AI to plan and build something more elaborate.
Any published playable can be forked and reworked by other creators, so games evolve through community contributions instead of staying frozen.
Generate images, sound effects and music for your game from the same credit balance, so you don't need separate asset pipelines.

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.
