Ember
Everything Ember does — on your machine.
A real model, a permanent memory, a voice, and an advisory guardian — all running locally, fully offline. Nothing leaves the machine unless you grant it.
A real model, on your own hardware.
Ember runs a full reasoning model directly on your computer — offline. No prompt round-trip, no shared tenancy, no usage meter. The model is yours — downloaded, not rented.
- Inference happens on-device, with no network call
- Uses your local GPU or CPU — no external compute
- Works with the network closed, on a plane or off-grid
It remembers, without a cap.
Ember keeps a private, searchable record of your work and days on disk — never in the cloud. No context window to overflow, no monthly purge. Ask what happened months ago and it actually knows.
- No token limit and no summarizer quietly dropping history
- Search it, correct it, copy it — a plain file on your disk
- Stored on this machine, opened only by you
It can act for you — only where you allow.
Ember ships with a toolbox — timers, reminders, notes, weather, unit math, device volume, and smart-home control — and every tool is opt-in. Screen awareness is in the works.
- Acts only on capabilities you explicitly grant
- Every action is sandboxed and written to the log
- Revoke any permission the moment you want to
It explains. You decide.
Ember's guardian is advisory. It explains what Ember is doing and asking for, and helps you decide — it never decides for you. You can read everything it knows, and it is never a replacement for your own security tools.
- Advisory only — the call is always yours
- Every capability request comes with a plain-language explanation
- Every verdict comes with the reasoning behind it
A voice that never leaves the room.
Talk to Ember out loud. Your speech is recognized on your machine, the reply is spoken by a voice generated on your machine — and it knows when you've finished talking, so there's no button to hold. Works with the network closed.
- Speech recognition and speech synthesis, both on-device
- Natural turn-taking — no push-to-talk
- English voices today, more languages in the works
