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.
