Readr

Readr is an innovative open-source ebook reader designed for curiosity-driven readers who want more than just to read. It allows users to interact with their EPUB and PDF books by asking questions about the content, with answers displayed in the margins pulled from the entire book. For example, while reading a science fiction novel, users can inquire about scientific concepts, and Readr will provide explanations referencing real science when applicable. Additionally, the tool features a natural-sounding text-to-speech function, enabling users to listen to their books on their device without needing an internet connection or creating an account. Its open-source nature and support for iPhone, iPad, and Mac make it a versatile choice for those who prefer privacy and local processing. Readr combines reading, questioning, and listening into one seamless experience, making it ideal for students, researchers, and avid readers alike who want a deeper engagement with their books.
