Brainstorm

Stress-test any idea with a panel of AI personas before you build it. Pick from 100+ expert templates -- CEO, engineer, designer, regulator, VC, and more -- describe your idea, and watch them debate it in a multi-round discussion. Each persona stays in character, challenges assumptions, and suggests improvements. When they're done, you get a structured summary with key insights, points of agreement, and concrete next steps.

How it works​

  1. Pick your panel. Choose 2-12 personas from 8 categories: Business, Engineering, Design, Science, Legal, Marketing, Domain Experts, and Customer Perspective.
  2. Describe your idea. Give the roundtable something to discuss. The more context, the richer the conversation.
  3. Configure your LLM. Use the free trial (3 sessions included) or bring your own OpenRouter API key for unlimited sessions. Pick any model -- you can even assign different models per persona.
  4. They debate it. Personas discuss over multiple rounds. They agree, disagree, build on each other's ideas, and vote when the discussion has reached a natural conclusion.
  5. Get a summary. A structured report with key insights, points of agreement, points of contention, recommendations, and an overall assessment.
