I built JARVIS — a local-first AI assistant you actually own (macOS + Linux, MIT)

A developer known as C.Studva has open-sourced Jarvis CLS, a local-first AI assistant for macOS and Linux under the MIT license. The assistant runs entirely on-device with no cloud dependency, using faster-whisper for speech recognition and local voices, and includes a model chain with an on-device fallback. The project comprises about 16,000 lines of code with 646 passing tests and has undergone five rounds of adversarial security review.

Siri, Alexa, and Google Assistant are thin clients. The intelligence lives on someone else's servers, every word you say leaves your house, and the moment the vendor has an outage — or you're on a plane — they mostly stop working. I wanted the JARVIS I was promised : always on, genuinely helpful, and mine . So I built one — Jarvis CLS — and open-sourced it MIT . ~/.jarvis — exportable and clearable. faster-whisper , local voices piper / pyttsx3 , and a model chain that always ends in an on-device fallback. Unplug the internet and it keeps talking.No account. No forced cloud. No fixed voice. No "sorry, I can't reach the server right now." It's ~16,000 lines, 646 passing tests , ruff- + mypy-clean enforced in CI , and hardened across five rounds of adversarial security review. macOS cd jarvis-unstoppable && brew install portaudio && make setup && make run Linux cd jarvis-unstoppable && bash scripts/install linux.sh && make setup && scripts/dev run.sh Leave the API keys blank to run fully local/offline, or add them for a cloud brain. Because an assistant that listens to everything you say should be one you can read the source of. It's MIT, source-available, and self-hostable. If that's the kind of assistant you've wanted, a ⭐ helps others find it — and I'd love to hear what you'd build on top of it.
