About
Hermitage is a single-user, local-first media sanctuary for your Calibre library. It opens your existing Calibre database read-only and renders the library as an edge-to-edge cover-art grid with a sliding detail pane, a tag-tree genre browser, a series browser, and an at-a-glance Library Insights window. Features: - Cover-art grid with per-cover dynamic colour glow - Codex detail view with hero-blur header, ISBN/Goodreads/etc. links - Genre browser using Calibre's dot-separated tag hierarchy - Series browser with index-range detection - Calibre-compatible search query language with virtual library support - Local reading history (recent shelf, read indicator, last-opened line) - Library Insights — top tags/authors, format coverage, hygiene audit - Export to JSON or CSV - Bundled premium typography (Fraunces, Inter, IBM Plex Sans Condensed) - 100% local — zero telemetry, zero accounts, zero network calls
