Previs the shot
A text prompt cannot hold a whole scene
AI video costs money per take, and one miss means paying again. A prompt cannot say where everyone stands, how they move, where the camera is and when it cuts.
Make those decisions first, in 3D, where they are cheap to change. The video model then gets the shot as a first frame, a greybox reference clip and a prompt that describes the real framing. It follows the blocking instead of guessing.

Your agent builds the scene while you watch
The same scene can be driven from three places, live in the viewport. Bring ChatGPT, Anthropic, OpenAI, Gemini, MiniMax, OpenRouter or CLIProxyAPI.
Chat beside the viewport and watch each change land. Sign in with ChatGPT or use your own key. Every change the agent makes is one undo step.
Open the studio, then press Cmd/Ctrl + B
Add CozyClay to Claude Desktop, Claude Code, Cursor or any MCP client. The agent edits the scene in the studio you have open.
