Show HN: Read any book frictionlessly with AI-powered hierarchical navigation (opens in new tab)

Hey HN! I built ProRead to solve the problem of getting stalled by walls of text in books or losing the big picture while reading.

Key features: • Start from a bird's-eye view, then zoom into any level of detail • Interactive knowledge maps show how concepts connect • Seamlessly navigate between chapter summaries and original text • Ask questions in context with AI assistance • High-quality text-to-speech for any book, any level of summary • Upload any EPUB and start reading immediately

We have 9 curated classics (Wealth of Nations, Crime and Punishment, etc.) ready to explore, plus you can bring your own books.

The idea came from cobbling through a workflow on books with LLMs until I decided to build it out! Would love your feedback!
