What it does
HN Companion summarizes Hacker News discussions into structured, readable digests so you can keep up without disappearing into the comment threads. The browser extension turns the standard HN page into a faster reading experience; the web app at hncompanion.com tracks what you’ve read and lets you save threads for later.
Why it exists
We read Hacker News every day, and the comments are often more valuable than the article. But the threading model rewards skimming over depth. We wanted summaries that respect the substance of a discussion while still letting us click through to the original comments when something looked interesting.
Tech Stack
The browser extension is JavaScript, HTML, and CSS. The companion web app is built with Next.js, TypeScript, and Tailwind, deployed on Cloudflare.
