KeywordSentinel monitors the web in real time and alerts you the moment your keywords are mentioned — with context, sentiment, and buyer intent. Track conversations across Reddit, Hacker News, Product Hunt, Google News, and more. Instead of manually searching, get instant alerts when people are asking for solutions, complaining about competitors, or showing buying intent — so you can act fast.

Hey Product Hunt 👋 I built KeywordSentinel after repeatedly discovering high-intent conversations days too late — founders asking for tools, users complaining about competitors, buyers actively searching for solutions on Reddit, Hacker News, and Product Hunt itself. KeywordSentinel monitors the web in real time and alerts you the moment your keywords show buying intent, pain points, or competitor mentions — with AI summaries and suggested actions. This is an early MVP and I’d love feedback from founders, marketers, and builders: • What sources should we add next? • What alerts would be most valuable to you? • What’s missing? Happy to answer anything — thanks for checking it out 🙏

When you think about early demand signals, which source matters most to you right now — Reddit, Hacker News, Google Search, or Product Hunt itself?

Curious — what’s one keyword or phrase you wish you’d seen earlier before traffic dropped or competitors moved in?
