A Nostr-powered personal cloud and self-hosted AI — notes, calendar, contacts, files, passwords

PosterChan is the Android half of a **Nostr-powered personal cloud** and a **self-hosted AI powerhouse** that runs on hardware you own. Your notes, calendar, contacts, files, passwords and mail live as encrypted Nostr events on a relay you run — no account with anybody, no subscription, no vendor holding the keys. **The personal cloud** - **Notes**: private, offline-first, encrypted to your own key. Write with no signal; it syncs when you have one. - **Calendar and contacts**: real **CalDAV/CardDAV**, so your phone's own calendar and contacts apps sync with your node like any other server — one account for both. - **Files and folder sync**: keep Documents and Pictures in step between phone and desktop through your own node. Contents are encrypted before they leave the device, so your server stores a folder it cannot read. - **Password manager**: logins, one-time codes (TOTP) and a generator, with **Android autofill** offering them in your other apps and browsers. Every entry is encrypted on your device — the relay holds ciphertext. - **Bookmark sync**: the companion add-on (Firefox, Chrome, Edge, Brave) keeps bookmarks in step across browsers, sealed with the same vault key. - **Mail**: your own IMAP/SMTP accounts, mirrored as encrypted events so search works without a round trip. **The AI powerhouse** - **Chat**: streaming LLM conversations against your own models or any OpenAI-compatible API. - **Generation**: images, music and video, produced on your own GPU rather than someone's rented one. - **Private search**: a metasearch engine bundled with your node, with AI overviews and citations. - **Live streaming**: go live from your camera or screen (NIP-53), and watch other people's streams. - **Voice and video calls**: 1:1 and group, over WebRTC. **And a full Nostr client**: feeds, threads, profiles, DMs, communities, mini apps and a web-of-trust relay. **Monero Zaps**: tip any post or person in **Monero (XMR)** with the ɱ button — private money for a private network, from the built-in Monero micro-wallet or the wallet you already use — right beside Lightning zaps. Self-hostable by design — point the app at your own instance; the default is poster.place.
