Everything you need.
Nothing to perform.
A calmer set of social tools, designed around friends who already matter.
Knock with a reason
Choose why you’re reaching out so your friend knows what kind of moment you need.
See who is around
Friends control their door and availability, making spontaneous conversation feel considerate.
Five focused minutes
A private room and a visible timer keep the conversation present, small, and meaningful.
Live conversation cues
Typing indicators and read receipts help the room feel responsive without adding noise.
Find people you know
Connect by username or discover suggested friends from email contacts you choose to share.
Stay a little longer
If you both want more time, mutually extend the room for another five minutes.
EPHEMERAL BY DESIGNThe conversation ends.
The conversation ends.
The connection doesn’t.
Knock Knock is deliberately temporary. Room messages are deleted when the session closes. We retain content-free interaction duration and your pair streak—not a permanent archive of what you said.
