Shelf Checkout

Scan any book's barcode and get a content analysis built from real evidence — personalized to every reader in your family. Know what's in a book before it's read. SCAN. ANALYZE. DECIDE. Point your phone at a barcode. In seconds, Shelf Checkout checks the book's content across 25 categories and gives you a clear verdict for each reader, based on the preferences you set. EVIDENCE, NOT GUESSWORK Premium checks are built from published evidence, not just inference. Every flag tells you how much evidence backs it, and analysis keeps improving in the background as more evidence is published. A VERDICT FOR EVERY READER Every family is different, and so is every reader. Set up a profile for each of your kids — and for yourself, if you're checking books for your own reading. Shelf Checkout gives each reader their own verdict: green, yellow, or red. 25 CONTENT CATEGORIES From violence and language to romance, death, and substance use, Shelf Checkout covers the content areas parents actually care about. You choose which categories matter and how sensitive each one should be. FAMILY SHARING, END-TO-END ENCRYPTED Share one library across your family's devices, whether they're running Android or iPhone. Everyone checking books for the same family sees the same shelf and the same verdicts, kept private with end-to-end encryption. SERIES AWARENESS Reading a series? Shelf Checkout knows. When content changes between books, you'll see exactly what shifts from one book to the next. BUILD YOUR LIBRARY Save books you've checked.
