Your computer,
sovereign. In one double-click.
A fast, GPU-accelerated native app — and an AI that lives 100% on your machine. Every action the agent takes goes through a permission verifier. Sovereign: no cloud, no account, no subscription.
100% local AI · no cloud · no account · no subscription · runs on as little as 8 GB — Apple Silicon (M1–M4), macOS 11+.
🇫🇷 Note: the app interface is currently in French — an English UI is coming soon. The download, license and updates already work worldwide.
Three principles, never compromised
Local-first. Secure. Governed.
Others bolt AI on top, tethered to the cloud. KiffOS flips it: the intelligence lives on your machine, and each of its actions is bounded by policy — not by a third party's goodwill.
Local-first
Inference runs on your machine. Your documents, your mail, your voice commands: nothing leaves your computer. Works offline.
Secure
The agent touches hardware, files and network only through syscalls verified one by one by policy. No arbitrary access. Deny by default.
Governed
Every sensitive action goes through a traceable policy and, when needed, your approval. You stay in control — always.
A native app, a sovereign core
All the intelligence on your machine — and under control.
On double-click, KiffOS runs natively on your Mac: Metal-accelerated inference, zero cloud. And every agent action — file, network, hardware — passes through a permission verifier before it runs. You live in a finished interface; the governance runs under the hood.
Explore the featuresThe KiffOS app
Cockpit UI, GPU-accelerated (Metal). Voice, documents, mail, files, app launcher. Ready out of the box.
KiffOS agent + policy
The agent only acts through verified syscalls, one by one: deny by default, your approval for anything sensitive. 100% local, no data outside.
Long-term vision: this same sovereign core on a bare-metal Rust micro-kernel (Ring-0) — research, distinct from today's native app.
What KiffOS does for you
A copilot that acts, not just answers.
Speak naturally. The agent understands the intent and executes it — under policy.
Voice
Hold a key, speak: "open Safari", "read my mail". Local recognition, action in a second.
Documents
Assisted, structured writing, exported to PDF / Markdown — generated locally, cleanly laid out.
IMAP / SMTP: assisted reading, replies and triage, a local contact book. Your mail stays yours.
Files & apps
Browse and launch your applications from the cockpit. The sovereign desktop, without leaving KiffOS.
Active defense (EHA)
A sentinel that maps your traffic locally and flags the abnormal — not a reactive antivirus. In Pro: alerts, automatic response and machine-to-machine mesh.
Zero cloud
No account, no server, no subscription. The 3B model runs comfortably on 8 GB, at ~40 tokens/s on Apple Silicon.
Your home obeys you — and you alone.
Control your connected devices by voice, locally, without going through a tech giant's cloud. The promise holds from day one: no command leaves your home. Hardware coverage grows with you.
The smart-home beta moves forward with its community: early users flag their priority hubs and devices. You don't endure a roadmap — you steer it.
Two editions, never a subscription

Download KiffOS and keep the local AI forever, for free. Go Pro the day you want to connect your mail, the web, your social feeds and your home — and arm the active defense.
