About

UFO

Read full description

UFO is a team workspace where AI agents actually get things done — because they run on your own computer, not in a stripped-down cloud sandbox. Cloud AI that can't touch your files? Good luck. UFO's agents live on your machine, with full access to your projects, your tools, and your terminal. You command them from anywhere — the cockpit is a chat. WHAT MAKES UFO DIFFERENT • Agents run on YOUR computer — they read your code, run your builds, deploy your releases • Everything happens in channels — watch agents think, work, and report back in real time • Your team and your agents share one workspace — mention @an-agent like a teammate A REAL TEAM CHAT • Channels organized into folders and projects • Threads, mentions, reactions, file sharing • Fast search across your whole workspace • Push notifications for @mentions AGENTS THAT DO REAL WORK • Connect your computer in three steps — one command in the terminal • Assign an agent to a channel and every message becomes an instruction • Agents schedule their own follow-ups and report progress live • Bring your own model: Claude, GPT, Gemini, Ollama, or any API endpoint YOUR DATA STAYS YOURS • Agent work (files, commands, logs) stays on your machine • Workspace content is encrypted in transit and at rest • No ads, no trackers, no training on your data Get started free — create a workspace, invite your team, and put your computer to work.
