Chat overview
The Brain chat shell — sidebar, conversation, and composer.
Open /chat after sign-in. The shell has three main areas:
- Sidebar — workspaces, chat history, search, new chat, projects
- Conversation — messages, tool calls, reasoning, authorization prompts
- Composer — mode, model, attachments, tools menu, message box
If no model path is available (no COMMAND_CODE_API_KEY and no custom models), Brain shows a clear “chat unavailable” empty state — configure models under Models or set the Command Code key.
New chat
- Sidebar New chat (or New shared chat in a team workspace when allowed)
