In your pocket
Press, speak, release. leo plays your podcasts and music, reads you your calendar and your mail, takes notes and works with your AI. With the earbuds you already own.
In design. Not for sale yet
leo. Your pocket computer, by voice.
Talk to it while you walk. Plug it into any screen when you need to see.
Two places, one device
No screen in your pocket. Any screen on the table.
At the desk
Plug leo into a monitor or a TV with a cable and see what it has done: the page you asked for, the document, the answer. You keep giving orders by voice.
Yours
The basic AI lives inside the device: it works offline, with no subscription and no account with us. If you want more, connect it to the model you choose. Open hardware and open software.
How it works
Three parts. Only one of them is awake most of the time.
1
A small chip that never sleeps
It watches the button, keeps the Bluetooth link to your earbuds and manages the battery. It draws almost nothing.
2
A processor with an AI accelerator, on demand
It wakes up only when you speak: hears you, understands, answers, and goes back to sleep. Plugged into a screen, it stays on.
3
A hub on your own computer
Paired with a QR code. It keeps your keys and connects your services: calendar, mail, messages, music. They never pass through us.
Inside
Built from open parts, in the open.
What it carries
- Always-on chip (nRF54L15, Zephyr): button, Bluetooth, battery and power control.
- Main processor with AI accelerator (candidate: Rockchip RK3576), powered on demand.
- Video out over HDMI or USB-C.
- Its own system: a minimal Linux image from open components, read-only root, signed updates, a software bill of materials.
- Local AI: speech recognition (Whisper), a small language model, speech synthesis (Piper). Optional cloud, with your consent, for what the local model cannot solve.
- Licences: CERN-OHL-S for the hardware, AGPL for the software.

What for
Four things people asked us to make possible.
Leave the phone at home
Podcasts, music, radio, calendar, mail and messages by voice, with the earbuds you already have.
Work by talking
Dictate notes, hand tasks to the AI and keep walking. When you reach a desk, plug leo into the monitor and see the result.
Show something in a meeting
Plug it into the TV in the room and present without a laptop.
Accessibility
For people with limited sight or mobility who prefer voice to a touchscreen.
Status, plainly
leo is in the design phase. It is not a product yet and cannot be bought.
We publish the design in the open as it moves forward. No hardware has been purchased yet; the figures above are targets. leo is a working name.
