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.

flowchart LR
    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.
