Home LMS - Book Management App: Stop buying books you already have

Hey Product Hunt! I built Home LMS - Book Management App because of a house repainting project that got out of hand. My house needed repainting so I had to unpack all my books. Standing there surrounded by stacks, I thought this is actually a good chance to finally categorize them properly. I had been meaning to do it for years. But I had no plan, no system, and it was going to take forever. So I packed them all back up the same way they came out, just wanting it done. That is when I noticed I had duplicate books. More than one. Books I had bought twice without realizing because I could not remember what I already owned. I wanted an app that let me register every book I own, where it is in the house, how many copies I have, the cover image, the price I paid, and the ability to export and import the whole thing so I never lose the data. I could not find exactly what I needed so I built it. That was the start. As I used it I kept finding things I wanted to add. The ISBN scanner so I could add books in seconds without typing. Multilingual search because my collection is split across English, Traditional Chinese, and Simplified Chinese. An AI Librarian so I could ask things like "what mysteries do I own that I have not read yet." A nearby bookshop finder for when I want something my collection does not have. Excel import for people who already track books in a spreadsheet. The philosophy is simple. Every time I think this would be useful, I build it in. Pricing: USD 7.99 one-time. No subscription, no cloud storage, no ongoing cost. Everything stays on your device. What I would love feedback on: What would make you actually switch from your current book tracking method to this? And what is the one feature that would make this a must-have rather than a nice-to-have? Thanks for checking it out. Phoebe, Skillnest Market
