Tech blog
Tech blog is an offline voice assistant that keeps the microphone open for interruptions and runs locally without cloud or accounts.
An offline voice assistant that keeps the microphone open during answers so users can interrupt mid-sentence or change their mind. It runs locally without cloud connectivity or accounts, requiring less than 15Gb of RAM and no dedicated GPU. The system features two-intensity barge-in, layered turn-ending decisions, and a tool gate that verifies proposed tool calls against the last spoken sentence. It supports skills, tool-calling, datetime, timers, a notepad, and shell commands. Conversation history is interrupt-safe, and the model mirrors the user's language dynamically. The architecture uses a hub process communicating with small services for full-duplex transcription, audio synthesis, and reasoning.
