About this app

ThumbThru helps you know what's actually inside a book before you (or someone you care about) reads it.

Scan any book's ISBN barcode, or search by title or author, and ThumbThru gives you a clear, honest content guide including language, violence, romantic content, substances, and the heavier emotional themes a book might explore. Not a rating. Not a recommendation. Just the information
you need to decide if it's right for you.

HOW IT WORKS

- Scan the barcode on the back of any book or search the title
- See an at-a-glance breakdown of content categories
- Tap any category for the specific details
- Set your content preferences once, and ThumbThru flags anything in a book that falls outside them
- Change your content preferences whenever you choose

YOUR PREFERENCES, YOUR CALL

ThumbThru doesn't decide what's appropriate—you do. Set the content categories that matter to you. When you scan a book,
anything that crosses your line gets flagged. You read the details and decide whether it's a fit for you.

This works whether you're choosing for yourself, vetting a book your kid wants to read, or building a reading list for your book club. Same tool, same honest information.

UPLOAD A READING LIST

Got a summer reading list from school? A book fair flyer? A list of recommendations from a friend? Snap a photo or paste the titles in. ThumbThru identifies the books and gives you content guides for the whole list at once.

ALSO IN THE APP

- Connect with a partner library for unlimited scans, free

WHY WE BUILT IT

You shouldn't have to get into the story before you know what you're getting into. You shouldn't have to guess based on the cover. You shouldn’t have to slog through endless reviews for hours to get the information you want. ThumbThru gives you
the same kind of thumb-through you'd do at a bookstore, in a few seconds, for any book.

GET STARTED

Open the app, sign in with Google, scan a book. Your free standard account gives you a set of monthly scans, but you can also connect with a partner library for unlimited scans completely free!

Questions, suggestions, or a book that didn't get assessed right? Tap "Report an Issue" in the app—we read everything.
