Doop

Doop is an infinite canvas that allows AI agents to draw together with you; it also functions as a design tool.

It’s not the same as asking AI to generate a design diagram. The Agent joins the drawing canvas through MCP, either operating in your name or via OAuth. Together, you can outline the structure, fill in the actual text, and review the resulting output on the same canvas; you can provide guidance throughout the process. Everything is transparent and accessible at any time, rather than relying on a “black box” to produce the final result.

It integrates with Claude Code, Codex, as well as any agent that supports MCP. The project is open-source and offers a macOS client; it can also be directly opened in a web browser.

It is currently in the beta phase and is available for free. It is suitable for teams that are already using the Coding Agent and wish to integrate the design process into the same workflow. However, pure design teams that are not accustomed to using the Agent may not be able to make use of its core features for the time being.
