What is it?
GAIA is a personal AI assistant aimed at handling routine work across your tools. After you connect Gmail, it triages the inbox each morning, drafts replies without sending them, and turns emails into todos. Connected to a calendar, it researches upcoming meetings and sends a reminder with the join link shortly before each one starts.
Beyond built-in jobs, you can describe a workflow in plain English and run it on a schedule or in response to events such as a new email, a GitHub commit or a Linear issue. Each integration has a dedicated specialist agent, and any MCP server can be added as a tool source. The assistant is reachable through iMessage, WhatsApp, Telegram, Slack, Discord, the web, a desktop app and mobile, all sharing one account and memory.
The project is a full-stack Nx monorepo with a Next.js web app, a FastAPI and LangGraph backend, a LiveKit voice worker and a Docker Compose setup for self-hosting via the @heygaia/cli. The license is PolyForm Noncommercial, so business use requires a separate enterprise license.
