Start a private chat How it works
  • Invite chat: no sign-up
  • End-to-end encrypted
  • Two seats only

Built for private conversations

A secure channel between two browsers — no accounts, no archive.

End-to-end encryption

Chat and media are encrypted in the browser. The relay only moves ciphertext.

One-shot invites

Share a link with one person. After they join, the invite closes.

Ephemeral controls

Burn timers and dissolve keep chats short-lived.

No accounts

No email or phone number. A seat cookie only proves the browser seat.
