Built for Real Readers
Features designed around how you actually make reading decisions
Per-Reader Verdicts
Different readers get different answers. Set age, maturity level, and custom filters for each reader profile. The same book can be approved for one reader and flagged for another.
Detailed Content Analysis
Scan a barcode or search by title. Get a full content breakdown across all 25 categories with severity ratings, highlights of what stands out, and a clear verdict. Add books to your shelf or save them for later.
Your Bookshelves
Every book you scan builds your personal library. Track what's on your shelf, what's saved for later, and revisit verdicts anytime. Switch between reader profiles to see each person's collection.
Honest About What AI Can (and Can't) Do
We tell you upfront: AI analysis has limitations. That's why community feedback exists.
Before your first scan, we lay it all out: AI has knowledge cutoffs, newer books may have limited data, and false positives happen. We're not hiding behind a "trust the algorithm" pitch.
That's why community verification is built into the core experience. When parents report inaccuracies, those corrections improve the analysis for everyone. AI starts the conversation, humans refine it.
Spoiler warnings included. We know analysis might reveal plot points — and we warn you about that too.
