Live Chat

Zero-knowledge encrypted ephemeral chat

How it works — zero-knowledge encrypted chat
  • Messages are encrypted in your browser with AES-256-GCM before leaving your device
  • The server only relays opaque ciphertext — it cannot read your messages
  • The encryption key lives in the URL fragment (#), which is never sent to the server
  • Nothing is stored — the room disappears when everyone leaves
  • Sender identities are random anonymous IDs generated per session
