Question: Can you suggest a tool that summarizes books and provides personalized recommendations?

If you're looking for a service that summarizes books and offers recommendations based on your tastes, BooksAI is a great option. The mobile app uses ChatGPT to create more than 40 million AI-generated summaries of books in many languages. It offers different types of summaries, including spoiler-free and filled, as well as AI-recommended books based on your favorite books. The app is good for readers who want to explore books from other countries or get recommendations.

Another option is Summarist.ai, which uses OpenAI's GPT-3 technology to generate summaries of books that are human-readable across a broad range of subjects. With a large library of more than 1 million summaries, you can get a quick understanding of the ideas and concepts in books like "Rich Dad Poor Dad" and "Becoming by Michelle Obama". It's good for personal use, as long as you're not violating copyright.

For more personalized book recommendations, NextThreeBooks offers a simple interface where you can enter your preferences, like genre and writing style, and get three recommendations. The system is designed to help readers find new books that match their tastes, so it's a good option for people looking to expand their reading list.
