# BookLooky > Free spoiler-free content ratings for children’s and young adult books using the Looky Rating System (LRS). Families, educators, and librarians get 0–5 scores and age bands without judgment or censorship. BookLooky (https://booklooky.com) is a free web app. Catalog ratings are AI estimates from descriptions and metadata unless labeled as an **official full-text LRS scan**. Story theme scores measure plot prominence — they are not warnings. LRS must not be used as the sole basis for removing books from schools or libraries. Important notes for agents: - Content Intensity (6): violence, romance, mental health, language, substance use, fear — strength/frequency - Story Themes (4): fantasy, LGBTQ+ representation, sci-fi, disability — presence/prominence, not warnings - Age bands: 4+, 8+, 13+, 18+ - Official transcript scans use the open-source rater; self-run copies of that tool are not BookLooky-certified ## Docs - [How LRS works](https://booklooky.com/how-it-works): Scales, AI estimate vs official full-text scan, integrity policy - [FAQ](https://booklooky.com/faq): Common questions about ratings, accuracy, and use - [About](https://booklooky.com/about): Mission and non-judgment values - [Book content reviews](https://booklooky.com/book-content-warnings): Parent-oriented content-review framing - [Full LLM context](https://booklooky.com/llms-full.txt): Extended single-file site summary - [Well-known llms.txt](https://booklooky.com/.well-known/llms.txt): Mirror for RFC 8615-style discovery - [AI discovery JSON](https://booklooky.com/.well-known/ai.json): Machine-readable discovery pointers ## Product - [Search books](https://booklooky.com/search): Title search for LRS ratings - [Search by criteria](https://booklooky.com/search-by-criteria): Filter by category scores and age - [Scan a book cover](https://booklooky.com/scan-book): Cover photo → rating pipeline - [For libraries & schools](https://booklooky.com/libraries): Bulk catalog scans; free for families and teachers - [For publishers & authors](https://booklooky.com/publishers): Print ratings and partnership overview - [Official LRS badge](https://booklooky.com/for-authors): Verified full-text scan, badge, marketing kit - [School library laws](https://booklooky.com/school-library-laws): 50-state map (Texas SB 13 and peers) and how LRS maps to subject-matter clarity - [Texas SB 13](https://booklooky.com/school-library-laws/texas): Deep dive for Texas school-library rules - [Blog](https://booklooky.com/blog): Product and reading updates - [Contact](https://booklooky.com/contact): General inquiries - [Sitemap](https://booklooky.com/sitemap.xml): Index of book and blog URLs ## Open source - [Official LRS rater (GitHub)](https://github.com/TheWootini/booklooky-official-lrs-rater): Transcript-based open-source rater used for official scans - [Official rater llms.txt](https://raw.githubusercontent.com/TheWootini/booklooky-official-lrs-rater/main/llms.txt): Package-level agent index ## Optional - [Privacy](https://booklooky.com/privacy): Privacy policy - [Terms](https://booklooky.com/terms): Terms of service, including LRS intended-use limits - [Official scan upload](https://booklooky.com/official-scan/upload): Author/publisher manuscript upload for certified scans
