Build and use your own Cursor or GPT. Open-source desktop (Apache-2.0). Customize the agent: skills, tools, skins, and models. Image, video, and audio workbenches ship ready — major-platform models already wired. Writing too: mix and match. The agent can change this product itself (snapshot → verify → roll back).
