The gear in the top bar holds the account things: your invite link, who you’ve blocked, the tour and sign out (and on a phone, day and night). It’s on every screen once you’re signed in.

Find it

Tap the gear in the top bar.

Use it

1

Invite someone

Open the gear and pick Invite someone. You get your own link; share it, and when someone joins through it we know you brought them. The dialog shows a count (Nobody has joined through your link yet. or how many people did), never who. Use Copy; if your browser can share (most phones, and some desktop browsers), a share button sits next to it.
The Settings menu open, with Invite someone marked

2

Block someone

Pick Blocked accounts to see who you’ve blocked. Blocked people can’t message you or talk to your brain, and they aren’t told. Tap Unblock next to a name to let them back in; an Undo appears for a moment if you change your mind.
The Blocked accounts dialog
3

Replay the tour

Pick Replay the tour to walk through the app again. It takes you to My brain and starts from there.

Switch day and night

On a desktop, the sun and moon button at the far right of the top bar flips the look.

On a phone there’s no room in the bar, so it’s in the gear menu as Switch to night (or Switch to day).

Good to know

  • Delete brain isn’t in this menu any more. It sits at the bottom of My brain, so it’s hard to hit by accident. See Privacy and deleting your brain.
  • People who talked to your brain without a name show as to your brain in the blocked list.
