CozyClay

CozyClay is a 3D previsualization studio for filmmakers and AI video creators planning a shot before rendering it. It lets you build a rough scene and use that scene as a visual reference for the finished video.

• Scene blocking: Arrange primitives, set pieces and characters, pose rigged figures, and plan character paths in a bird's-eye view.
• Shots and storyboards: Build still panels or moving shots, choose lenses, and preview dolly rails, crane moves and cuts on a timeline.
• AI video references: Export first and last frames, shot videos, depth and normal passes, storyboard sheets and OTIO cut lists; keyframe packs combine images, a reference clip, camera data and a model-specific prompt for tools such as Seedance, Kling and Veo.
• Optional character motion: Generate motion through the Kimodo bridge, sequence motion prompts and correct poses with inverse kinematics tools.
• Assistant control: Let external assistants edit the scene through MCP, or use the built-in agent with a ChatGPT account; agent edits share the editor's undo history.

The studio is free and open source under AGPL-3.0. Local editing runs on your machine in a Chromium browser and works offline. It requires Node.js, a mouse and a keyboard. The ChatGPT-connected agent uses an external service; it isn't an offline assistant.

The hosted playground lets you edit and download a project, but video export requires the local Studio. The hosted site and official npm package collect anonymous usage metrics without uploading project content through that telemetry. You can disable metrics in the local Studio.
