Turn any chaotic digital book archive into an autonomous, self-organizing reading portal using Calibre-Web Automated, a digital library manager featuring hands-free format conversions, metadata fetching, and e-reader synchronization. Readers can drop raw ebook files into the automated intake directory and watch the system instantly convert between twenty-eight distinct file types, repair malformed EPUB internal markup, and fetch enriched metadata from Hardcover, Kobo, and ISBN databases. The responsive web reader lets you browse collections, read directly in any desktop or mobile browser, and organize titles into dynamic rules-based Magic Shelves that update automatically. Built-in KOReader sync harmonizes reading progress and bookmarks across mobile devices and e-ink readers, while native OPDS feeds connect seamlessly to your favorite external reader applications. Administrative tools empower you to run hybrid SQL and fuzzy duplicate detection scans, perform batch metadata editing across entire series, enforce cover art changes directly into source files, and auto-dispatch newly ingested books to Kindle or Kobo devices via scheduled email delivery. Granular multi-user controls allow administrators to assign folder permissions, restrict downloads, enforce dark mode themes, and authenticate readers securely through OAuth and OpenID Connect identity providers.
