Hey Product Hunt 👋 I built this after spending 15 years managing IT projects and watching teams sink millions into ideas that should never have shipped. The problem wasn't the people — it was that the tools they used to evaluate ideas were too optimistic. Everything told you the TAM was huge and the market was ready. Nothing told you your unit economics break at 5,000 users, or that there's an incumbent with a moat you can't crack. Is My Idea Any Good? tries to fix that. You describe your idea, Claude Sonnet analyses it against a ruleset I've built from real project failures — and you get: A viability score (1–5) with plain-English reasoning Realistic market sizing — TAM/SAM/SOM with the caveats most tools skip Tech stack recommendation + running costs at 1k and 10k users If AI-powered: actual cost modelling at 100 / 1k / 10k users Marketing tactics specific to your idea (not "use social media") Red flags — the 3–5 most likely reasons this idea fails Real companies that tried something similar and what happened to them Free tier gives you a 3-point snapshot. The full report is $19 one-time — no account needed, no subscription. Would love your feedback — even though this has been tested with 100's of ideas it might still get something wrong or miss something obvious. There is a feedback section at the bottom of the page. Happy to answer questions below.
