itsrouk/your-ai-focus-group ? reverse-engineered prompt

Build me a web app that lets someone test a product idea, tagline, or pitch with an AI focus group.

The app should ask for a short idea or concept, then generate a panel of 10 diverse synthetic personas based on that input. Let the user pick 3 to 5 personas that feel like the right audience, then ask up to 5 open ended questions and show each persona answering one at a time so it feels like a real conversation. After that, give a simple scorecard with what worked, what needs work, how much the panel agreed, and the main insights that came up.

I want it to feel fast, clean, and easy to use, with a way to copy the full transcript at the end. Use the Gemini API for the AI responses, and make it work as a modern Next.js app with TypeScript and a nice responsive UI. If anything is unclear, look up the current docs online and make sensible choices.
