Our summaries are generated by "Cobalt", our cutting-edge AI model specially trained for book analysis and synthesis. Developed by our team of AI researchers and literature experts, Cobalt reads every book entirely, identifies key concepts, fundamental ideas, and practical lessons with remarkable precision. The model then structures these elements according to our exclusive cognitive methodology, optimizing understanding and retention. Each generated summary is supervised and refined by our specialized editors before publication, combining the power of AI with human sensitivity to offer you summaries of unmatched quality.
Our summaries are designed to be read in 8 minutes on average. This duration has been scientifically optimized to maximize information retention while respecting your precious time. Of course, you can take more (or less) time if you wish to deepen certain concepts or take notes.
We offer three subscription plans: Discovery (access to 5 summaries per month), Premium (unlimited access to text summaries), and Elite (unlimited access to text and audio summaries, plus exclusive features like personalized notes and discussion groups). All our subscriptions include a 7-day free trial and can be canceled at any time.
Absolutely! We value suggestions from our community. Premium and Elite subscribers can submit up to 3 book suggestions per month via the "Suggest a Book" feature in the app. Our team evaluates all suggestions and prioritizes the most requested titles. If your suggestion is selected, you will receive a notification and be among the first to receive the summary.
Our summaries are designed to capture the essence and key lessons of a book, but they do not claim to replace the full reading experience. Rather, they serve three main purposes: helping you determine which books deserve your full reading time, allowing you to quickly assimilate essential concepts from many works, and offering reminders of important ideas from books you have already read. Many of our users tell us they read more full books after discovering interesting titles via our summaries.
Our team is available to answer all your questions about our application, our summaries, or our AI technology. Do not hesitate to contact us.
