Rooms, PINs, and messages that find you.

SHIPPED

Password-protected group chat. Open or closed rooms, PINs, file sharing, desktop and web push, so a message finds you even with the tab closed.

The problem

Group chat usually means an account, an app install, and a feed that follows you. Sometimes you just want a room with a password that works in any browser.

The solution

Rooms that open with a name and, when closed, a PIN. Files ride along on R2, and push means a message still finds you after the tab closes.
