Hey PH! 👋 I built IdeaCheck because I was tired of the "just build it and see" approach to validating startup ideas. Every founder I know (including myself) has spent months building something only to discover the market didn't care. The problem isn't lack of effort — it's lack of honest, data-backed feedback before you start. Most idea validation tools give you generic AI-generated fluff. I wanted something that actually searches the web for real competitor data, market sizing reports, and pricing benchmarks — then scores your idea across 10 weighted dimensions. The "Most Likely Ways to Die" feature is my favorite part. Instead of sugarcoating, it tells you the top 3 ways your startup will probably fail. Brutal? Yes. Useful? Absolutely. The tech stack: Next.js + Hono on Cloudflare Workers, Gemini 2.5 Flash for analysis, Tavily for real-time search. The whole analysis runs in under 5 minutes. Try it free — your first analysis is on me. Would love your feedback on what dimensions or data sources you'd want to see added!
