This chat is end-to-end encrypted between your key and my key. I can read these messages only when I log in with my nsec.
Owner login (nsec)

How this works
  • This browser has its own Nostr key; visitors get an automatic keypair.
  • The site owner can log in with their nsec to see the inbox.
  • Public lounge is an encrypted global group chat.
  • “Private chat” sends encrypted DMs only you and I can read.
  • Links (images, videos, etc.) are auto-linked in messages.
TODO List
  • Improve UI/UX for mobile devices.
  • Implement message read receipts for DMs.
  • Allow image/file uploads in messages (Blossom/nostr.build).
  • Optimize relay connections and error handling.
  • Add support for NIP-17/NIP-44 encrypted messages.
  • Introduce notifications for new messages.
  • Implement message search functionality.
  • Customize connected relays and their statuses.
  • Create user profiles with avatars for visitors.
  • Export and import visitor keys for portability.
Privacy Notice
This application operates in a decentralized manner using Nostr relays. No centralized servers store your messages; instead, they are distributed across relays. While the application does not log or store your data, please be aware that relays may retain copies of your messages. For sensitive communications, ensure you trust the relays you connect to.
