A realtime synthetic-data engine for world models. Make a photorealistic scene from crude 3D objects online or brought by you.

1. Take a pictures of an object and upload it. AI converts it into a 3D object. Drag and drop it into the scene builder. Give the scene builder a stylistic text prompt instruction. Watch the scene get created!
2. The scene is fully controllable in realtime with full support for scaling, rotating, translating, and editing the text-based style.

Photo on phone → 3D object → AI-stylized editable scene.
