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.

Weekend hack: HackerTube. I was annoyed with YouTube's recommendations so I had Claude filter down 43M comments over 20 years of HN to 6,454 videos that keep being recommended. *Significantly* better viewing experience, ~2 hours with Opus 5.5: https://t.co/JIhXN7OSh1
- Excellent recs without any logins (state is kept in local browser session) - Thumbnail is a representative frame from middle of the video instead of the super duper A/B test hyper-optimized user uploads - Underlying data from the comment analysis as one zip file, point your Claude at it and ask for your own version - HackerTube Longs ✊
A bit more on the process: I use Claude Code (desktop app for Mac), Opus 5.5 on Medium effort as my default. I only talk to Claude and have it do everything, the only "manual work" I helped with in tandem was in the browser (reminiscent of MenuGen): 1) I had to create some kind of API key from Google Cloud UI to query YouTube for video metadata, 2) I booted up a VPS box for serving and 3) I bought the domain name. Once the box was up I gave Claude the IP and told it update, secure, harden, deploy and optimize the code, and it did the whole thing.
Many awesome projects that would have normally taken weeks/months even can now be few-shotted for breakfast. What else are we not thinking of.
