A lightweight Chrome extension called HNswered lets Hacker News users track replies to their posts quickly without leaving the browser. After entering a username once, the tool scans public stories and comments, flags any direct responses, and surfaces them in a side‑panel inbox with an unread badge. No login, no server, and no write permissions are required.

HNswered builds its notification engine on a simple observation: every reply on Hacker News points to a parent comment. By storing the IDs of a user’s own contributions locally, the extension watches the public comment stream for matches and routes matching replies into the Chrome storage‑backed inbox. Users can manually refresh after posting or let the panel catch up when Chrome wakes from sleep.

The project ships a pre‑built distribution folder, so developers can install it directly from the GitHub repo without running Node or a build step. A security‑audit guide lives in the docs, and contributors can rebuild the code with pnpm if they wish to modify the matching logic. HNswered offers a self‑contained way to stay on top of community feedback.
