Built this for a hackathon. It’s a Chrome extension that rescores every comment in a Reddit or HN thread using actual relevance instead of karma. How I built it with Claude: I used Claude (Sonnet via API) for pretty much the entire thing — generating the Chrome extension scaffold, writing the content extraction logic that pulls comments from Reddit’s DOM, and building the ranking pipeline that sends comments to ZeroEntropy’s zerank-2 model for instruction-reranking. Claude also helped me write the sentiment classifier and the UI for switching between ranking modes. Whole thing took about a day because Claude handled most of the boilerplate. How it works: You install the extension, plug in your ZeroEntropy API key, and it rescores every comment in the thread. You can set modes like depth, controversy, actionability — and it re-sorts everything. Also works as a classifier and sentiment analyzer which I didn’t expect going in. What I found running it across threads: 32% of the most relevant answers have 1 karma or less Median best answer: 2 karma. Top-voted comment: 14 karma. 7x gap. Posts with 50+ comments? Best answer: 2 karma. Top comment: 259. 130x gap. 79.3% of the time the most relevant answer is NOT the most upvoted It’s free to use — just need a ZeroEntropy API key (they have a free tier).
