The ReadBetter Company has created a science-based reading encouragement system to help young readers discover books to read, a system that incents readers to read regularly and includes to reading coach that is powered by Machine learning and AI technology. Users get access to reading clubs where they can read books with others who belong to the same school or the same city or the same reading level. Reading Clubs are a social environment where readers can discuss books they are reading, have fun together and grow while they are having fun. Learning to read better can mean different things to different readers. We are enabling readers to read more books in genres they enjoy, enable readers to expand their reading horizons and find new topics, genres and themes to that they may find interesting and we're enabling today's non-readers to discover how much fun it can be to read and immerse yourself in a story through a book. Our current focus is to help young readers gain the life-long benefits that come from being well-read. Our innovative platform can also help adult readers get personalized book recommendations.
