PreperAi - Talk to your users. Before they exist.

Hey Product Hunt! 👋 I'm Mohamed — solo founder, software engineer, and the person who built the wrong product twice. Both times, same mistake: I had an idea, got excited, spent weeks building — and launched to silence. Not even crickets. Just nobody. The problem wasn't the execution. It was that I never talked to real users before building. User interviews felt too slow. Research tools were too expensive ($89/month before you have a single user?). So I skipped it every time. And paid the price every time. PreperAI is what I wish existed back then. Here's how it works: → Describe your idea in 2–3 sentences → Get 5 AI-powered personas instantly — each with a real job, a real pain point, and a specific reason to say no to your product → Chat with them directly. They stay in character. They push back. They tell you what would make them pay — or walk away. The whole thing takes 10 minutes. Not 10 weeks. 🔥 What's live today: ✅ Instant persona generation from any idea ✅ Full AI chat — each persona holds their personality across the whole conversation ✅ Free plan: 2 projects, 20 conversations/month — no card needed ✅ Pro: $9/month, unlimited everything One question for you 👇 What's the biggest assumption you're currently making about your users that you haven't validated yet? Drop it in the comments — I'll tell you exactly which persona type would challenge it the hardest. 🎯
