HN Buddy – a Hacker News Chrome extension
Another HN Chrome extension when a dozen already do this identically.

Find hackernews audience whose comments matches most to you.
This is based on tf-idf weighted keywords match from comments. Covers data from Jan 1, 2020 through May 31, 2026. Keywords that are too rare or too broad across authors are filtered out before scoring.
Due to above filtering, a lot of the authors are NOT covered here. Full coverage would have yielded more than a few trillion records, and I don't have that much compute or disk.

You can also see who talks most about certain topic or keyword. For example,
NSA: https://hn-buddies.stupidlabs.lol/?keyword=nsa
Trump: https://hn-buddies.stupidlabs.lol/?keyword=trump

This also lets you uncover duplicate accounts. For example:
1. "fdklhhjf" and "selamcan"
2. "angkatoto" and "jalantoto"
3. "Donnakravo" and "dommakravosec" and "kravossedonna" and "kravosdonna"

Competent hardware port but the original Claude Buddy already exists.
Daily markdown reports suggest build ideas based on trending tech signals.
Pretty HN visualization but there's no actual functionality beyond the aesthetic.
Cleaner inline reader for HN comment subtrees without the navigation clutter.
Keyword dimming and trend arrows actually help filter HN noise effectively.
