Karpathy：用 Claude 两小时做出 HackerTube，把 HN 二十年 4300 万条评论筛成 6,454 个视频

中文译文

• 不登录也有好推荐。 状态只存在本地浏览器的会话里。
• 缩略图换成视频中段的一帧。 上传者反复做 A/B 测试、调到极致的那些封面，在这里不出现。
• 底层数据打包成一个 zip。 评论分析的结果整包给出，你可以直接把它丢给自己的 Claude，让它给你做一版。
• HackerTube Longs ✊。 这句是拿 YouTube 的 Shorts（短视频）反着说：这里放的是长视频。

英文原文

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.
