What is Vexa AI agent?

Vexa is a open-source, voice-controlled local AI that transcribes speech, parses intent with Phi-3, and writes code files to your machine — all offline.

How to build a local voice AI agent like Vexa?

Grab Whisper-tiny for STT, Ollama with Phi-3 for intent, FastAPI backend. Hack JSON outputs with format flags and regex. GitHub repo has the bones.

Is Vexa safe for writing code on my computer?

It has path checks and no-overwrite rules, but it's not foolproof — sandbox it yourself before production use.
