Stacks: Book Scanner & Library

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.
