Show HN: Hacker News book recs as study guides

Hey HN, I loved Pieter Mae's HN book map from 2024 (https://hnbooks.pieterma.es/) and immediately wanted to dive into a lot of the nonfiction books. I didn't have a ton of time to read all of them though, so I made this project to generate study guides for any arbitrary book. Think of it like free sparknotes powered by Gemini. Hope you all can learn as much as I did!
