Five layers. Nothing hidden.
Scroll and it comes apart. Every part is a real, off-the-shelf component you can look up, and the full bill of materials, with prices, is public.
- Glass and touch5-point multi-touch over the whole screen. Setup, chat and everything else happen right here.
- 10.1″ IPS display1920×1200. The breathing orb, the live status, the conversation.
- Raspberry Pi 5 · 8 GBQuad-core Cortex-A76. Runs Debian 13, the model, memory, voice and search.
- Active fanGoverned by the Pi's firmware: quiet (often off) at idle, it ramps under load. Low-50s °C sustained, no throttling observed.
- Enclosure, speaker and storageA built-in speaker so it can talk back, and an included 256 GB NVMe M.2 SSD.
Raspberry Pi 5
Powerful enough to run a real language model entirely on the device, and small enough to sit on your desk. A boot-time RAM budget keeps the chat model loaded; under pressure it drops to a smaller fallback model and says so.
10.1″ touchscreen
Set it up and talk to it right on the screen. No computer is needed to get started, ever.
256 GB, included
Storage for local models, your conversations and documents. Offline reference packs are planned 1.0 additions, not yet release-verified. NVMe storage is included in all newly shipped devices.
Speaker + push-to-talk mic
A built-in speaker so it can talk back, and a USB mic that's live only while the button blinks red. Listening and speaking both run on the device.
Debian 13, AI built in
A full Debian system with the assistant built in. SSH is documented and never removed, and the code ships as readable source on the device.
Private by default
A capable on-device model, free forever. Optional Boosted mode uses Claude on your own Anthropic key, and every answer is labelled with the brain that produced it. Optional Autonomous mode adds actions from your own Telegram, and every email send or calendar change waits for your yes.
For the people who read spec sheets.
The same facts as the manual that ships on the device, where every unit also serves its own burn-in certificate at /docs/certificate. What it all adds up to is on the features page.
What you unpack.
