An agent-native computer that works while you sleep
Agents browse, use files and run code inside a secure cloud environment kept separate from your own computer.
Access and switch between models from leading AI labs per task, with no individual API keys required.
A very large library of plug-and-play skills for research, creation, automation and coding, plus connectors to your existing apps.
Schedule and trigger tasks that keep running when your computer is off, such as weekly reporting jobs.

Local capabilities, reachable anywhere — publish your own apps and agents on the web with permissions you control.
Publish local web pages, REST interfaces, MCP services, documents, Markdown and spreadsheets as a single uumit.ai address you can open from a phone or another computer.
Every published item starts private. Choose private, invited members or everyone, and revoke or narrow access at any time from the client.
Install the UUMit publish skill into an agent on the same machine so it can identify running apps, confirm scope and publish, then verify the returned URL.
Browse and call real-world APIs and datasets — POI, maps, weather, OCR, enterprise and finance data — and expose your own APIs to others.
