PosterChan is the Android client for a self-hosted PosterChanAI instance — a Nostr social client with a
built-in AI assistant and an end-to-end encrypted password manager.

Password manager: logins, one-time codes (TOTP) and a password generator, with Android autofill
offering them in your other apps and browsers. Every entry is encrypted on your device — the relay
stores ciphertext and nothing else, so no server can read your passwords.
Password sync: your vault follows you across devices through your own relay, with no account and no
third-party service in the middle.
Browser bookmark sync: the companion browser add-on (Firefox, Chrome, Edge, Brave) keeps your
bookmarks in sync across browsers, sealed with the same vault key, and fills these logins into web pages.
Nostr social: feeds, threads, profiles, DMs, communities and a web-of-trust relay.
AI chat: streaming LLM chat, with image, music and video generation.
Live streaming: go live from your camera or share your screen (NIP-53), and watch other people's streams.
Voice and video calls: 1:1 and group calls over WebRTC.
Self-hostable: point the app at your own instance — the default is poster.place.
