Gaia

GAIA is an open source personal AI assistant that acts across the tools someone already uses instead of waiting to be asked. It works through the inbox, calendar and task list, opens the day with a briefing and a plan, drafts replies, moves meetings, chases follow ups and reports back on what it completed and what still needs a human decision. It is aimed at professionals who lose hours to digital housekeeping rather than at developers, and it requires no technical setup. More than 50 native integrations plus MCP connectors reach Gmail, Slack, Notion, Calendar and over a hundred other services. Automations are described in plain language, set to a schedule or a trigger, and run as a chain across those tools with a notification on completion. Long jobs continue while the user is away. A memory stores what it is told once and acts on it weeks later, and every memory is visible, editable and deletable. Approvals are requested before risky actions. The assistant is reachable from a web app, desktop and mobile apps, a command line client and messaging apps including iMessage, WhatsApp, Slack and Telegram. The code is published, so it can be audited and run on the user's own server. One paid plan is published, at $30 a month billed monthly, covering everything the assistant does: inbox triage and drafted replies, meeting briefs and reminders, todos it works on rather than merely tracks, workflows, long running jobs, memory and priority support. Yearly billing is advertised as two months free. An Enterprise tier is priced around the team and adds SSO, SCIM and audit logs, custom integrations, self hosting or private cloud, a private Slack channel, a dedicated engineer and an SLA.
