Take our interactive demo for a spin below. Look up different books, explore their ratings, and see how Bookrata puts you in control of what you read.
The World's Only Consistent, Transparent, Scalable Rating System for Books
Bookrata is the first content rating system for books designed to give readers transparency, easy to digest ratings, and control over what they choose to read. Bookrata uses a custom AI algorithm meticulously trained to recognize words, scenes, and context in six different categories.
Six Categories. Five Tiers. One Standard.
Tier Scale
Ratings are based on level of content, amount of content, and how that content is presented. It is unique to each category. We make no value judgements with our ratings.
Search the Way It Should Be
Our filtering system allows you to choose the content you are comfortable with AND search for up to five tags to find the stories you want. Publishers can manipulate category, genre, and key words when they publish on Amazon to try and push their books to the top of the rankings.
But in Bookrata, the AI algorithm picks five tags based on the actual themes of the book. You aren't stuck by genre. If you want a historical-fantasy-regency-romance, you can find it at Bookrata.

Can't I Just Ask AI to Compile Online Book Reviews?
Yes, you can, but AI is only summarizing other people's opinions. Bookrata's library ratings are built from the actual text of the book — every page, rated the same way, every time.
💡Here's the Thing
One recent bestseller has over 400k reviews with an average 4.7 star rating. Do you have time to read 400k reviews? Do you know exactly how to frame your AI prompt to get the exact information you need? Let Bookrata do it for you.
Online reviews are a compilation of the opinions of readers who have their own values, morals, and priorities. Most of the reviews are about the story, not the content. Bookrata library ratings are different: they come from the actual text of the book itself, not from what people said about it — and they focus exclusively on content.
Yes, you could use your own AI prompt, but beware of garbage in-garbage out! An AI can only compile what's already online — it hasn't read the book. Bookrata's library ratings rate the real text, page by page, so you get consistent, verifiable answers instead of a guess.
The Legal Solution to Rate Books at Scale
We only rate books that are in our legal possession. Authors and publishers deserve to profit from their work! Marcus is an independently published author and understands how important it is to get paid for his creative work. We don't sell or release any of the books we rate. By default, we link each book with an affiliate link to Amazon, but are happy to add an author's preferred bookstore if requested.
