Folio Library

Your library, finally organized — and shared with the people who live in it. Folio is the easiest way to keep track of the books in your home. Point your camera at a barcode and Folio pulls the cover, title, and details automatically — no typing required. From there, it's yours to shelve, rate, and revisit whenever you like. But Folio isn't just a personal list. It's built for households. Live with a partner, roommate, or family who also reads? Everyone gets their own shelf, their own ratings, and their own "currently reading" — while still being able to see the full household library in one place. No more "wait, do we already own this?" No more duplicate copies of the same paperback. Scan it in seconds Point, scan, done. Folio fetches the cover art, author, publisher, and description automatically, so adding a book takes moments, not minutes. Track what matters to you Ownership and reading progress are tracked separately, because they're not the same thing. Mark a book as yours, a shared family copy, or one you're borrowing — and independently track whether it's on your TBR pile, in progress, finished, or abandoned halfway through (no judgment). See the whole household shelf Everyone's books, side by side. See who owns what, who's reading what, and whose glowing (or scathing) review is waiting for you on a book you're considering. Never buy a duplicate again Add a book and Folio flags it if someone in your household already owns it — so you can borrow instead of buy. Build a wishlist together One shared wishlist for the whole household, sorted by priority, so gift-giving and bookstore trips are easier. Organize your way Custom tags, custom shelf locations ("Bedroom shelf," "Storage bin," "Loaned out"), and personal lists for whatever you're curating — a summer reading list, a book club queue, an all-time favorites shelf. Recommend without the group chat Found something a housemate would love? Send it straight to their shelf with a note attached. Rate, review, and remember Star ratings and personal notes for every book, visible to your household so everyone can see what you actually thought — not just what you finished. Folio is designed for the way real households read: independently, together, and usually with strong opinions about who left a book facedown and cracked the spine.
