Spines: The Book Scout

True Story!

In-app purchases

About this app

Your next great read is hiding on a $2 shelf somewhere. Spines helps you find it.

Point your camera at any thrift store, used-book shop, or library sale and Spines reads every spine, matches each title against award databases and reader ratings, and tells you in seconds which books are worth grabbing — based on your personal taste.

No more standing in the aisle googling every title. No more leaving Pulitzer winners behind because you didn't recognize the author. Spines turns a chaotic shelf into a curated list.

HOW IT WORKS
1. Scan — Point your camera at any bookshelf and snap a photo
2. Identify — AI reads the spines and matches each book automatically
3. Discover — See ratings, awards, and personalized recommendations
