JARVIS — local-first AI assistant

in progress

A voice assistant that runs entirely on-device — no cloud APIs, no black boxes. Every model in the loop runs on my own machine, and every stage I can't explain, I rebuild until I can.

2026.08Voice loop working end-to-end: on-device ASR (mlx-whisper) → local LLM (Ollama) → TTS
nextWake-word classifier, trained from scratch on raw MFCC features
thenIntent parsing & planning
thenAction execution
thenComputer vision

Named after the one in Iron Man, obviously. Tony Stark built his in a cave; I'm building mine on a MacBook.

"Computer science is not about coding. It never has been. It is about human thought. Can machines be kind? That is my question."
