Build Your Own
Tell it what you're building in a sentence, and you'll work together from there. Nine specialist AI models handle 3D, animation, scenes, music, sound, visual effects, UI, game logic, and multiplayer, orchestrated through a typed runtime that compiles straight to a browser game. Chinese prompts work end to end.
Ship To Any Platform
- Mobile (iOS, Android) — via Capacitor, wraps your game in a native shell with access to device APIs
- Desktop (Windows, macOS, Linux) — via Tauri, lightweight native binaries under 10MB
- Steam — Tauri build, packaged with Steamworks SDK
- Discord Activities — runs inside Discord via their Embedded App SDK
- WeChat & Douyin Mini Games — export with a platform-specific adapter to reach China's mini-game ecosystem
- Web portals (CrazyGames, Poki, Newgrounds) — integrate their SDK for ads, leaderboards, and distribution
Same codebase. Different packaging. Ship mini games into China or Steam and web portals worldwide, all from one build.
