The companion

The app that powers all of it

The device is the face; the companion is everything behind it. A small Mac app that sets it up, keeps it connected, and does the work the device is too small for.

Sets up your device
Flashes it, names it, keeps it connected over Bluetooth or USB.
Connects your agents
The tools you already use, like Claude and Cursor, can reach the device and put things on the glass.
Does the heavy lifting
Speech, models and workflows run here, so the device stays small and quiet.
