Your books deserve better than a spreadsheet. Plumerie is a home library app for people who own physical books. Catalog what you have, share with family, and lend to friends — all without ads, affiliate links, or Amazon. WHAT MAKES IT DIFFERENT Family sharing that actually works. One shared library where everyone can browse, with separate reading histories. Built for households that share shelves. Lending that doesn't require a group chat. Lend a book to anyone — even friends who don't have the app. Plumerie tracks who has what so you don't have to. Scan to add in seconds. Point your camera at a barcode. Done. Plumerie looks up the cover, title, author, and description automatically. AI-powered search. Can't remember the title? Describe it. Plumerie finds it. 45 languages supported. ISBN-routed to the right book data source automatically. THE PHILOSOPHY Read what you own. Borrow before you buy. Plumerie isn't trying to sell you books. There are no recommendations engineered to drive purchases, no affiliate links, no ads. Just your library. Free tier: up to 100 books (individual) or 500 books with 5 family members. No trial period. Permanently free. Built by one person in Helsinki. Terms of Use: https://www.plumerielibrary.com/terms
