Question: Is there a tool that can summarize long books into key points and quotes for easier understanding?

BooksAI.com is a good example that uses ChatGPT to generate summaries, key points, quotes and to-do lists from books. The service can help you zero in on what's most important with a summary that's written in plain language. You can sign up for an account to summarize more books and annotate documents, making it a good option for book lovers and researchers.

Another powerful option is BooksAI, a mobile app with more than 40 million AI-generated summaries of books. It offers different types of summaries, including spoiler-free and spoiler-filled options, and can recommend books based on your reading history. The app is available in nine languages and is good for readers who want to explore books from different countries.

It's got a broad library of more than 1 million summaries and is licensed for personal use, so it's legal.
