Strategy & The AI-Native Founder

Which AI tool is best for brainstorming ideas?

ChatGPT, Claude or Gemini, used deliberately: ask for many ideas, push for range, then make it argue against them. In a Wharton study, GPT-4 produced 35 of the 40 best product ideas when judges compared it with students in an innovation class, but other studies found AI ideas are more similar to each other than people's. So ask for 30 ideas in different styles, then the five most unusual, then the reasons each would fail, and add your own constraints (budget, city, customer). For a team session on a shared board, Miro has AI built into its whiteboard, with a free plan of 3 editable boards and 10 AI credits a month, and FigJam, Figma's whiteboard, has AI on Figma's plans. The rule: let AI widen the list and people choose from it.
