HNswered is a small Chrome side panel for Hacker News replies.
Set your HN username once. HNswered watches the public stories and comments you have authored, surfaces direct replies in a local inbox, and keeps an unread badge in the toolbar.
No HN login. No server. No write access. Just public HN data, matched locally.

What It Does
- Finds replies to your HN stories and comments, even when the original comment is deep in a thread.
- Shows a clean side-panel inbox with unread/read filters.
- Lets you refresh on demand after posting something new.
- Catches up after Chrome has been asleep or closed.
- Keeps state local in Chrome storage.
How It Works
One simple idea: every reply on HN points at its parent. HNswered remembers what you wrote and watches public comments for replies to those.

A["your HN username"] --> B["items you wrote"]
C["public HN comments"] --> D{"reply to<br/>one of yours?"}
B -.-> D
D -- yes --> E["your inbox"]
D -- no --> F["ignore"]
That's it. No login, no server, no backend you have to trust.
