TrendWatcher watches what the world is searching for and building right now — across Google Trends, Hacker News, GitHub Trending, Product Hunt, Dev.to and arXiv — and turns each live trend into a concrete, buildable AI product idea. Every idea is scored 1–10 for real opportunity, not hype. We break the score down across demand, feasibility, timing and whitespace, and we show you the evidence behind it: the exact trend, the source, and why now is the moment. WHAT YOU GET • A live feed of AI app ideas, refreshed as new trends break • A 1–10 opportunity score on every idea, with the reasoning shown • The source signal behind each idea — no black box • Filters for source, audience, demand, feasibility, monetization, timing and whitespace • A clear "who is this for" and "why now" on every card • Save the ideas worth coming back to WHO IT'S FOR Indie hackers, founders, product managers and engineers who want to spot the next AI opportunity early — and skip the ideas that only look good on the surface.
