AI Analysis

●●SolidSolve My ProblemNiche Gem

HN keyword monitoring beats manual checking, but newsletter aggregators already exist.

Strengths

•Solves genuine friction for HN enthusiasts—relevance scoring filters noise, 6-hour cadence balances freshness with digest format.
•Free tier at 3 rules lowers friction; AI summarization saves clicks versus raw link spam.
•Targets a warm audience (HN readers) who understand the value proposition immediately.

Weaknesses

•Newsletter monitoring and keyword alerts are solved categories (IFTTT, Zapier, Substack, paid news platforms).
•No visible differentiation from RSS + automation or existing HN tools (HN search, front-page APIs, HN Lobby). Keyword relevance scoring is table stakes for modern alerts.

Post Description

Built this because I was manually checking HN every day for mentions of topics I care about. HNWatch lets you set keywords and get an email digest every 6 hours with matching posts — each one scored for relevance and summarized so you're not clicking through noise. Free tier: 3 rules. Paid: unlimited at $5/month. hnwatcher.watch Happy to get feedback from HN since you're the actual target user here.
