A Consistent, Transparent Rating System for Books
Bookrata gives readers clear, easy-to-read content ratings so they can discover books that match their own values. A custom AI algorithm reviews words, scenes, and context across six categories.
Six Categories. Five Tiers. One Standard.
Tier Scale
Ratings consider the level and amount of content, along with how it is presented. The criteria are specific to each category. Bookrata does not make value judgements in its ratings.
Search the Way It Should Be
Choose the content levels you are comfortable with, then use up to five tags to find the kinds of stories you want. Publisher-selected categories, genres, and keywords on Amazon can be chosen with rankings and visibility in mind.
Bookrata's algorithm selects five tags based on the book's themes, so you are not limited to a single genre. If you want historical fantasy with Regency romance, you can search for that combination.

Can't I Just Ask AI to Compile Online Book Reviews?
You can, but the result will summarize information already available online. Bookrata's library ratings are built from the actual text of the book, with each book rated using the same standards.
💡Here's the Thing
One recent bestseller has over 400k reviews and an average 4.7 star rating. Reading enough of those reviews to understand the book's content would take time, and an AI summary depends on the sources and prompt. Bookrata offers a consistent content-focused alternative.
Online reviews reflect each reader's values and priorities, and most focus on the story rather than specific content. Bookrata library ratings come from the actual text of the book itself and focus on content rather than opinions about it.
An AI answer based on online sources can only work with the information those sources provide. Bookrata's library ratings review the book's text page by page using consistent criteria.
The Legal Solution to Rate Books at Scale
We only rate books that are in our legal possession, and we do not sell or release the books we rate. Marcus is an independently published author and understands the importance of paying people for their creative work. By default, each book includes an Amazon affiliate link. Authors can request a link to their preferred bookstore.
