Stacks: Book Scanner & Library

Scout any bookstore or thrift shelf and see which books fit your taste. Catalog your whole library from a photo, then let your AI Librarian pick what to read next.

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 — on iPhone and iPad.

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

SCOUT SHELVES & BUILD A WISHLIST • Scout mode: point your camera at a bookstore or thrift-shop shelf and see which books fit your taste — before you buy • Librarian's picks: curated recommendations you can browse by category or search across the whole catalog • Add any book to your Library or your Want list in a tap — from picks, a scout, or a search

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

DESIGNED FOR IPHONE & IPAD • On iPad: a sidebar, multi-column shelves, and a two-page book view that fills the screen • Portrait or landscape, with Split View and Stage Manager • Your library and Want list stay in sync across devices

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 LIBRARIAN (PRO) • A weekly note on what to start next — from your own unread shelves, with the reasons • Picks chosen for your shelves: real books you don't own yet, tuned to what you've loved • A book-loving AI that knows your entire library: what to read, buy, or gift — grounded in your actual shelves, not bestseller lists • Chat with any single book, in its own voice • Share a Shelfie: your library as a story card — rainbow shelf, reading fingerprint, most-shelved authors

Your library is backed up privately and automatically — no account, no sign-up. New users get 3 free shelf scans. Try the Librarian free, then Stacks Pro unlocks the weekly note, personalized picks, unlimited chat, every Shelfie card 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.
