Features
Keyboard first, mouse optional
Helicon is fully keyboard operable. A command palette jumps to any project, session or action, slash commands work in the composer the way they do in the CLI, and a picker switches model and reasoning effort mid thread. Nothing in the app requires a pointing device.

Why a terminal user cares
The most common objection to a GUI from someone happy in a terminal is that it slows them down. It only does if it forces the mouse. Helicon was built so the fast path is the keyboard and the pointer is a convenience.
What the palette reaches
- Any project, by name, including worktrees.
- Any session, so history is one search away.
- Actions: new thread, stop, background, settings, theme, usage.
Slash commands and the picker
- Slash commands in the composer, matching what the CLI accepts.
- A model and reasoning effort picker you can change without restarting the thread.
- Goal controls from the composer as well as the goal panel.
Every feature here ships in the free Muse Code desktop app for Windows, macOS and Linux. Try Helicon in your browser on sample data, or install Helicon and point it at your own muse login.
