One sentence in, a playable game out
Describe your game in a sentence. Play it minutes later, right in your browser. No code, no SDK, no installs. Cinevva generates the 3D, music, sound, and animation for you. Then you tweak it, remix anyone's game, and share a link that plays anywhere.
Create your own game
Rig and Animate Your Own Characters
Bring a static model to life in your browser. Fit a skeleton to it, retarget 260 public-domain motions onto that skeleton, or describe a move in words and get the clip. Everything comes back as a game-ready GLB for Unity, Godot, Blender, or Three.js.
Auto Rigger
Upload a GLB, FBX, or OBJ and get a skeleton with skin weights, without placing a single bone by hand.

Animation Library
260 CC0 clips retargeted onto your own rig, from walk cycles to sword combat to dances.

Build With the AI You Already Use
Claude, Claude Code, and Cursor can build Cinevva games over MCP. Connect once and your assistant edits your games right on our servers, even with no browser tab open. Open the game in the creator and it goes further: it watches the running game, tests it with screenshots and simulated input, and streams every change onto your screen. The connector is free on every plan.
