Stacks: Book Scanner & Library
AI Librarian for Your Books
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Photograph a bookshelf and Stacks catalogs every book on it — titles, authors, covers, page counts — in one scan.
Your shelves, in your pocket.
Photograph a bookshelf and Stacks catalogs every book on it — titles, authors, covers, page counts — in one scan. No typing, no barcode-scanning books one at a time. Six shelves, one tap each, and your whole library is with you everywhere.
SCAN A SHELF, GET YOUR LIBRARY
• One photo catalogs an entire shelf — 20, 30, 40 books at once
• Real cover art, page counts, and publication years fill in automatically
• Honest AI: spines it can't read are flagged with their position, never guessed
A LIBRARY THAT LOOKS LIKE A LIBRARY
• The Shelf view renders your books as actual spines — width from page count, color from the real cover
• Sort by author, genre, or color: your shelves as a rainbow
• Grid and list views, search, and smart shelves: Unread, Favorites, Lent Out
KNOW YOUR OWN TASTE
• Every scan reads your shelf and tells you something true about your taste
• "Read next" picks come from books you already own — starting with your unread pile
• Insights: pages owned, top genres, most-shelved authors, books added over time
NEVER LOSE A BOOK AGAIN
• Standing in a bookstore wondering if you own it? Search your library in a second
• The lending tracker remembers who borrowed what, and since when
• Rate, mark read, and keep notes on every book
YOUR READING CONCIERGE (PRO)
• A book-loving AI that knows your entire library
• What to read next, what to buy, what to gift — grounded in your actual shelves, not bestseller lists
• Chat about any single book: themes, characters, what to read after it
Your library is backed up privately and automatically — no account, no sign-up. New users get 3 free shelf scans. Stacks Pro unlocks the concierge and 50 scans a month: $4.99/month or $34.99/year with a 7-day free trial.
Stacks is for people whose books are part of who they are. Scan your shelves and see your library the way it deserves to be seen.

What's new in this update:
• Scout a shelf — point your camera at any bookstore or thrift-shop shelf and instantly see which books are worth grabbing for your taste, with one tap to save them.
• Librarian's picks — book recommendations right on your home and Librarian screens. Tap a pick for details and a description, browse by category, or search the whole catalog.
• Want list — a wishlist for books you don't own yet. Add picks and scouted finds, then mark them owned when you get them.
• A fresh, more readable design — bigger, warmer type across book pages, summaries, and your margin notes.
• A new welcome screen to help you get started faster.
• Fixes and polish: a cleaner book-detail menu, larger margin notes, and more reliable Librarian chat for big libraries.
