Show HN: HackerBooks – HackerTube, but for books mentioned on HN

HackerBooks, inspired by Karpathy's HackerTube, is a new platform listing approximately 16.5k books mentioned by at least two different Hacker News commenters since 2007. Each book entry links back to the original comments. The data is downloadable, and the site, including its data pipeline, was largely built by Claude Opus 5.5, with the creator primarily providing direction and handling logistics like domain registration. The platform counts mentions, so it's not a perfect recommendation system.
