Knock turns rooms into chat rooms.

You join a room, see other people who are there, and knock on someone if you'd like to talk. They can accept or pass silently. No profiles, no swiping, no names unless you both want them.

We built it because most of the best people in your day are sitting near you, and saying hi shouldn't have to be a big deal.

A signal, not a profile

Just a signal and a name.

When you join a room, you appear as a signal, not a profile. Only people in the same room can see you, and only while you’re both there.
