Blender Copilot
A Copilot-style AI chat panel inside Blender that runs its agent loop in Blender's own Python process, executes the model's generated code against the live scene, and wraps every conversational turn in a single undo step.
Blender Copilot is a chat panel that lives inside Blender and runs an agent loop in Blender's own Python process, so the model's generated bpy code executes directly against the live scene with no separate bridge process or second copy of the scene to keep synchronized. Every turn of the conversation, however many individual operations it performs, can be undone as one step with a single press of ctrl-Z, and the add-on's own transcript keeps a receipt describing what that undo step does and does not cover.
The project documents both what it builds and what it deliberately does not: it describes a capability guard that repeated testing showed the model's sandbox does not actually need, and so was not built, and publishes results, including failed attempts, rather than only favourable examples. A worked example in the README shows a spaceship built and iterated on over five successive natural-language prompts.
