# Your work brain

> The brain that starts as yours alone

Every account starts with a brain of its own. Yours was created the moment you joined, it is called **My Work Brain**, and it begins with exactly one member: you, as its Owner.

That member list is the whole privacy model. Nobody can open, search or connect an agent to a brain they are not a member of, so a brain whose member list is just you is yours alone. There is no separate visibility setting to check; who can see a brain is precisely who is on it.

## The safe default

Your work brain is the default destination for what you capture. When your agent saves a conversation, when you drag a file into an inbox without thinking too hard, when a connected tool pushes something in overnight, it lands there unless you deliberately pointed it somewhere else (once you hold write access to several brains, your agent names the destination each time).

That makes it the right place to capture freely: half-formed thoughts, sensitive notes, rambling conversations with your agent. Decide what to share later, deliberately.

## It grows with you

Because your work brain is an ordinary brain that you own, it is not a dead end:

* **You can share it** if you choose, by adding members with roles, the same as any brain. Many people never do, and it stays private for as long as its member list stays at one.
* **You can move knowledge out of it** with [promoting](/brains/promoting): a deliberate copy of specific knowledge into a shared brain, leaving your private original untouched.
* **You own its settings**, including its [filing mode](/filing/auto-ingest) and its lifecycle.

One honest note for team accounts: brains belong to the workspace, like files in a company drive. Day to day only members see a brain's content, but workspace admins administer all of the workspace's brains as part of running it, for example exporting or reassigning a brain when someone leaves.

## Try it

1. Open **My Work Brain** and look at its Members list: just you, as Owner.
2. Ask your connected agent to *"save a note that I prefer morning meetings"* and watch it arrive in the inbox.
3. Check the filed page afterwards: private, cited, and yours.
