Hey Product Hunt 👋 I'm Stéphane, a solo developer from France — and KiffOS is what I've been building, alone, for the past months. I was tired of one thing: today, "AI" means the cloud + a subscription + your data living on someone else's servers. I wanted the opposite — a real assistant that lives entirely on my own machine. So KiffOS runs 100% locally: 🧠 A local AI agent — ask it in plain language (or by voice, push-to-talk) to open apps, write documents, search and read your files. 🔒 Zero cloud, zero account, zero telemetry. Your files and conversations never leave your Mac. 🦀 Built on a Rust core with a permission verifier — every action the agent takes is checked, nothing runs behind your back. ♾️ No subscription. A one-time, perpetual license (€99). There's a free tier too — local AI, voice, documents, files — so you can try the whole thing before paying. KiffOS Pro adds the connected world (mail, web search, social, smart home, remote models) — but only when you choose to connect it. It's notarized by Apple, auto-updates, and runs on Apple Silicon (M1–M4), macOS 11+. 👉 Download & try it free: https://kiffos.fr 📖 5-minute getting-started: https://kiffos.fr/guide I built this solo, so your honest feedback means everything — what would make you actually use a local AI agent every day? Ask me anything 🙏 Note: the app UI is currently in French — English UI coming soon. (Download, license & updates work worldwide.)
