Quire is a native Android EPUB reader برای people who self-host calibre-web. It browses شما library over OPDS, downloads books on demand, renders them با Readium, و syncs reading progress (و later bookmarks) to a small companion server you run yourself (Quire Server, included). Features: - OPDS catalog browsing و search - EPUB reading با Readium (font, تم, line-height controls) - Reading progress همگام‌سازی across devices via شما own Postgres - Multi-user from day one - One credential: شما existing calibre-web account Privacy: - No analytics, no crash reporting, no third-party SDKs - Network تماس‌ها go to شما calibre-web و شما همگام‌سازی server only - Credentials stored in Android Keystore Source code, server, و documentation: https://github.com/vitofico/quire Optional AI features (off by default): when شما Quire Server administrator configures an AI endpoint (مانند a self-hosted Ollama or a third-party provider) و you opt in from تنظیمات, Quire shows generated book insights — author, summary, series, تم‌ها, craft یادداشت‌ها, comparative anchors, curiosities about the book و its author, و book-club style discussion prompts — grounded با citations from Wikipedia و OpenLibrary. A separate Library Insights screen builds a personal reader profile from شما finished books و suggests further reads (both from شما own library و via OpenLibrary discovery). No AI request leaves شما network until you explicitly opt in, و a single tap in تنظیمات deletes the cached profile.
