Overview
What aulo does.
aulo is a local-first voice agent that controls the computer it runs on. You talk to it and it talks back. It runs shell commands, opens and drives apps, works in a browser, and reads the screen when it has to.
aulo is planned as one daemon, aulod, with a gRPC API. Native desktop apps with chats (SwiftUI on
macOS, WinUI 3 on Windows), the aulo CLI and remote gRPC clients all reach it, so it can also run
headless on a server.
aulo is at the specification stage: the spec, the research, the plan and the gRPC API reference exist; there is no code yet. The name comes from the Greek aulos, a reed pipe: breath turned into voice.
Features
Built for real workflows.
-
Voice first
Hands-free listening with a wake word or push-to-talk, end-of-turn detection and barge-in, and replies that stream as speech.
-
Swappable speech
Every speech-to-text and text-to-speech engine can be swapped at runtime.
-
Computer control
Shell, apps, browser and desktop accessibility; screenshots plus synthetic input only as the last resort.
-
MCP both ways
A built-in MCP client, and aulo as an MCP server for other agents.
-
Any model
Local models (runa, Ollama, LM Studio, llama.cpp) and remote providers (OpenAI, Anthropic, Gemini, xAI, OpenRouter, any OpenAI-compatible endpoint), set per tier and per chat.
-
Plugins
Tools, speech engines, LLM providers, skills and hooks.
