Scan any book's barcode and get content analysis tailored to your reading preferences. Know what's in a book before you read it.

SCAN. ANALYZE. DECIDE.

Point your phone at a barcode. In seconds, Shelf Checkout analyzes the book's content across 25 categories and gives you a clear verdict based on the preferences you set.

PERSONALIZED TO EVERY READER
Set up reader profiles with custom content preferences. Whether you're choosing books for yourself, your kids, your students, or your book club, each reader gets their own verdict: green, yellow, or red.

25 CONTENT CATEGORIES
From violence and language to romance, substance use, and more, Shelf Checkout covers the content areas that matter to you. You choose which categories to track and how sensitive each one should be.

MAKE SHELF DECISIONS
After scanning, decide what to do with each book for each reader. Add it to your bookshelf, save it for later, or reject it. Add private notes to remember why you made your decision. Your choices stay organized and easy to revisit.
