One thing I've wanted for years is a personal bookshelf app that makes it easy to digitize my physical book collection.

For the Contra × Wonder Challenge, I finally decided to design it.

The idea is simple. Add books by scanning the barcode, taking a photo of the cover, or entering the ISBN manually. Once added, every book lives in a clean digital library where I can organize what I'm reading, what I've finished, and what I want to read next.

What surprised me most was Wonder itself. I expected it to speed up the process, but I didn't expect it to understand the direction I had in mind so accurately. It helped me iterate much faster while still giving me the precision to shape the experience the way I wanted.

This challenge gave me the perfect excuse to finally design a product that's been sitting in my head for a long time. Hopefully, it's also the first step toward turning it into a real app. Public link: https://app.wonder.so/rudy-p-agnel/files/019f2f48-08b9-7ce4-b9d8-b01e1629a62d
