Brain is shared memory for your agents: one searchable knowledge base with
cited summaries, reusable skills, and handoffs that carry work between agents
— read and written by every MCP client you use.

Access is per workspace and currently early access with limited capacity.
Registering tells us which plan to open first, and gets you one email when it
does.

- **Considering on-premise?** [What a deployment involves](/brain/docs/on-premise),
  including the hardware question that decides most of it.
