Your Own Library

Ever bought a book you already own? Or lent a favorite and forgotten where it went? Your Own Library turns the books around your home into a collection you can search, find, and enjoy. Know what you own, where each copy lives, and what to read next. TRY IT. THEN MAKE IT YOURS. Preview a book scan or an import before you buy. For new users, saving books and using the full library requires Complete Library, a one-time in-app purchase. No subscription. The price is shown before you purchase. KNOW BEFORE YOU BUY ANOTHER COPY Scan an ISBN barcode or enter one by hand. See book details, review the match, and check your collection for the same work or edition. Keep track of multiple copies without losing their individual histories. FIND THE BOOK, NOT JUST THE TITLE Give each copy a home: Office > Walnut Bookcase > Shelf 3. Search your catalog, browse your shelves, and move books as your collection changes. Add notes, tags, collections, and reading status to make it yours. LEND YOUR FAVORITES WITH CONFIDENCE Remember who borrowed a book and when. Record a return in one tap, with an optional reminder to help you follow up. REDISCOVER WHAT YOU ALREADY OWN Find unread books and get suggestions from your own collection with Ask My Library. Each suggestion explains the match and can show where the copy is shelved. Recommendations run on your device. BRING YOUR COLLECTION WITH YOU Preview and import CSV or supported JSON catalog files. Export your catalog in CSV or JSON. Your saved books and exports remain accessible if purchase access changes. A PERSONAL LIBRARY, WITHOUT AN ACCOUNT Your catalog lives on your device. There are no ads or tracking. Looking up an unknown ISBN sends that ISBN and a random installation identifier to our metadata service for book details and fair-use limits. Cover images may load from their credited sources. ALREADY USING YOUR OWN LIBRARY? Existing Complete Library purchases remain valid. People who used the original free version keep their existing free library features. Start with a book you love. Unlock Complete Library and give every book a place.
