## Summary

Andrej Karpathy built HackerTube, a YouTube alternative that uses Claude to filter 43 million Hacker News comments from 20 years into 6,454 recommended videos. Karpathy says it took about 2 hours with Opus 5.5, and the Chinese-language repost by indigo, who quotes him, adds that users should let their own agents handle recommendations.

## AI translation

Recommendation, personalized! Andrej's weekend project: HackerTube. He had Claude sift through 20 years of HN's 43 million comments to pick out 6,454 videos that kept getting recommended. It noticeably improved the viewing experience, and it took about 2 hours with Opus 5.5! I think many of us have suffered from YouTube's recommendations for too long, and from now on we should all let our own Agents help with recommending content 👀

## Quoted post @karpathy

> 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://hackertube.org/
> 
> - 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.
