Arcanum Reader

Read ebooks from your own Grimmory or Booklore server, or a folder in iCloud Drive. Highlights and notes sync back, it reads aloud, and Home learns your taste.

Arcanum Reader is an ebook reader for people who keep their own library. Point it at your Grimmory or Booklore server and every book is there, with your reading position, highlights and notes syncing both ways. No server? Drop EPUBs into a folder in iCloud Drive and read them on every iPad you own. Nothing passes through anyone else's cloud.

READING • EPUB, Kindle AZW3 and MOBI, FB2, PDF and plain text • Paged or scrolling, one or two columns, with real control over margins, line spacing, fonts and width • Light, sepia and dark themes, or follow the system • Highlights in six colours and four styles, with notes, all synced to your server • Look Up, Translate and Share from the system menu, right next to Highlight • Search inside the book • Read aloud with the voices built into iPadOS, sentence by sentence • Downloads for offline reading; anything you do offline syncs when you are back

YOUR LIBRARY • A home page in the style you would expect: Continue Reading, shelves for the genres you actually finish and rate highly, top rated, recently added • Browse by genre, search by title or author, sort any way you like • The same book in two formats shows as one card; pick the edition when you open it • Community ratings from Goodreads, Amazon and Hardcover, as synced by your server • Surprise Me: one book, chosen for you, with a reason, and a button to try another • Reading time this week, your streak, and a seven-day chart • Share a book's highlights and notes as Markdown

WANT MORE? • Ask a Bindery server for books you do not have yet, straight from the app • Bring your own Anthropic API key and Surprise Me will ask Claude, taking your mood into account

ARCANUM NEVER SEES YOUR BOOKS The app talks only to servers you choose. There is no account with us, no analytics, and no copy of your library anywhere but your devices and your server.

Arcanum Reader works with a Grimmory or Booklore server, or on its own with a folder of books. It is free and open source.
