A Session is a single AI planning conversation within a project. When you create a session, you select a type — this tells Brunel’s AI what kind of work you’re planning, helping it ask better questions and structure the output more usefully.
Creating a New Session
- Select a project from the sidebar
- Click + New Session
- Enter a session name (tip: name it after the ticket or task — e.g.
PROJ-123: Add rate limiting)
- Select a session type
- Click Create — you’ll be taken directly into the session
Session Types
| Type | Best for |
|---|
| Feature Planning | Planning new features, enhancements, or product additions. Use this when you’re defining requirements, dependencies, and implementation approach for something new. |
| Bug Fix | Debugging and resolving issues. Use this when you need to diagnose a problem, identify root cause, and plan a targeted fix. |
| Refactoring | Code improvement and restructuring. Use this when the goal is improving the codebase without changing external behavior — performance, readability, architecture cleanup. |
| General Planning | Any planning conversation that doesn’t fit the above. Use this for spikes, research tasks, migrations, or anything exploratory. |
Not sure which to pick? General Planning is always a safe default. The session type helps orient the AI, but you can describe your work clearly in your first message and the AI will adapt regardless.
The Multi-Session Interface
Brunel supports multiple open sessions simultaneously, displayed as tabs at the top of the workspace.
- Switch instantly between sessions by clicking their tab
- Unread badges appear on tabs when a session has new activity while you’re in another session
- Close a session tab by clicking the × on the tab — this closes the view only. The session and all its history remain exactly where you left them; reopen it from the sidebar to continue where you left off
- Rename a session at any time by right-clicking its tab or using the session context menu
All open sessions and their full message history persist across app restarts — you’ll pick up exactly where you left off.
