Sub-chats let you run multiple parallel conversations within the same p0 session. Each sub-chat is an independent thread with its own conversation history and context.
Creating a sub-chat
To create a new sub-chat within your current session:
- Type
/clear in the chat to start a fresh conversation thread
- The new sub-chat opens as a tab alongside your existing threads
- Start chatting with p0 in the new thread
All sub-chats within a session share the same git worktree but maintain independent conversation histories.
Managing sub-chats
Sub-chats appear as tabs in the session interface, making it easy to navigate between different conversations:
- Tab navigation - Click tabs to switch between sub-chats
- Pinning - Pin important sub-chats to keep them easily accessible
- Renaming - Give sub-chats descriptive names to organize your work
Each sub-chat maintains its own metadata including ID, name, creation timestamp, and mode.
Independent modes
Each sub-chat can operate in its own mode independently:
- Sub-chat A could be in Plan mode exploring a new feature
- Sub-chat B could be in Agent mode implementing a bug fix
- Sub-chat C could be in Plan mode analyzing architecture options
The mode setting is stored per sub-chat and persists across sessions using localStorage.
Use cases
Sub-chats are useful for:
- Exploring different approaches - Try multiple solutions in parallel and compare results
- Separating concerns - Have one sub-chat for frontend changes and another for backend
- Quick questions - Ask questions without interrupting your main implementation thread
- Parallel tasks - Work on multiple independent features simultaneously
- Documentation - Keep a sub-chat for documentation updates separate from code changes
Use sub-chats to keep your main conversation focused while exploring side questions or alternative approaches. You can always merge insights back into your primary thread.
