Karpathy built HackerTube with Claude, filtering 6,454 videos from 43 million HN comments

Karpathy released the weekend project HackerTube, using Claude to filter 6,454 repeatedly recommended videos from 43 million comments spanning 20 years of HN. The entire project was completed in about 2 hours using Opus 5.5. The site provides recommendations without requiring login, thumbnails are taken from a representative frame in the middle of the video, and the comment analysis data is packaged as a zip file that can be handed to Claude to generate your own version. He used the Mac desktop version of Claude Code and manually did only three things: applying for a Google Cloud API key, starting a VPS, and purchasing a domain. After that, he had Claude handle updates, security hardening, deployment, and code optimization.
