Unique key per room
Your browser makes the room's key and keeps it in the invite link. Messages and files are locked on your device before they're sent, so not even DiffWeb can read them.

that vanish.
Anonymous. No sign-up. Spin up an encrypted room, share a private link with up to 4 people, and talk freely. When the chat ends, the room disappears for everyone.

Create a secure room
ReadyHow it works
Four steps. Zero sign-up.
- 01Create
Name your room, set a limit and a self-destruct timer.
- 02Share
Send the private link. Revoke or replace it any time.
- 03Talk
Messages, photos, videos and documents, end-to-end encrypted.
- 04Vanish
End it, let it expire, or just leave. Access is gone everywhere.
Security by design
Built like a vault. Simple as a link.
Instant vanish
When a room ends, every open tab loses access at once. Old links and refreshes show nothing.
You control the door
Approve each person or set a password. Lock the room, replace the link and remove anyone instantly.
Anonymous by default
No account, no email, no phone number. Pick any name, or get a random one.
Clean file sharing
Photos are cleaned on your phone to remove hidden location data before they're sent. Risky file types are blocked.
Abuse protection
Rate limits, one-tap reporting and a 2FA-secured safety team keep rooms safe.
