Question: I'm looking for a personalized book discovery platform that offers tailored suggestions based on my favorite genres.

First up is The StoryGraph, an information retrieval system that tracks your reading activity and offers recommendations based on your preferences, mood and themes. It's got AI-based recommendations, mood-based discovery and a collection of tools like reading challenges and a reading journal. You can import data from Goodreads, too, and there's a mobile app.

Another good option is What Should I Read Next?, which uses sophisticated AI to recommend books based on your current mood, preferred genres and specific story elements. It's got mood-based recommendations, and you can refine its suggestions by adjusting factors like emotional depth and character development, so it's good for readers who want to try something different.

If you want something more streamlined, try NextThreeBooks. This AI-powered system offers three recommendations based on your preferences for genre and writing style. With its simple interface and GPT-3 technology, it's designed to help readers find new books as quickly and easily as possible.

Last is BooksAI, a mobile app that uses ChatGPT to offer more than 40 million AI-generated summaries of books. In addition to personalized book recommendations based on your favorite books, it also offers summaries in multiple languages and celebrity book lists, so it's a good option for readers who want to explore books from different cultures and genres.
