I built an AI tool to validate app ideas before building — launching on PH this Wednesday

I kept building things nobody wanted. Weeks of work, zero users.

So I built DemandProof — paste your idea or URL, pick your target user, and get an honest verdict in under 60 seconds.

The problem

I kept building things nobody wanted. Weeks of work, zero users.

What it does

• Build / Pivot / Kill verdict powered by AI + real-time web data
• Demand score with reasoning
• Target persona breakdown
• Where to find your first users

Stack

Next.js, Supabase, Claude API, Tavily, Lemon Squeezy
