Virtual machines you own, share, and take over
Computer agents get a machine of their own, a full-screen browser you can grab, and logins that last.
An agent that drives a real computer needed a real place to live. A virtual machine is now a thing you own. It has its own page in the sidebar, an owner, and the same sharing rules as everything else in Brain.
And when an agent gets stuck on a login, you take the browser over on a full page, type into it yourself, and hand it back.
A machine is something you own
A machine used to be an invisible side effect of running an agent. You could not see it, name it, or let a teammate use it, which made it impossible to reason about what your agents were actually running on.
- Virtual machines: have their own page in the sidebar.
- Owning and sharing: work the way they do for integrations and projects. Private by default, then shared with named people or the whole workspace.
- Several agents: ride one machine, each in its own container with its own files, its own disk and its own browser. Ten always-on agents cost you one machine, not ten.
- An agent that mostly waits: still gets the whole machine in its busy moments. It reserves a share and bursts to the rest.
- The bill: splits across whoever is on the machine at the moment it is measured, so your cost falls as neighbours arrive.
Take the browser over
Watching the agent's browser in a small floating panel was fine for looking and useless for helping. Most of the time the agent is stuck on something a person clears in five seconds.
- The agent browser: opens as a full-screen page instead of a panel floating over one.
- Typing and pasting: work in the browser you have taken over.
- Passkey prompts: are turned off during a takeover, so a login stops freezing the whole session.
Logins stick
A browser session that only lived for one call meant logging in again on every single run. That is slow, and it is the fastest way to trip a provider's fraud check.
- A browser login: survives between runs, not just inside one run.
- An always-on agent: comes back to its own container and finds its own files where it left them.
- A machine: is released after a quiet spell, and every run or heartbeat keeps it warm.
