AI Brainstorming Prompts

I need ideas for [goal/challenge]. Generate 15 ideas with these constraints: 5 that cost nothing, 5 that take less than a week, and 5 that are "wild card" (ambitious but possible). For each, give me: the idea in one sentence, why it might work, the biggest risk, and a first step. Don't self-censor - include bad ideas too.

I want to [goal]. Instead of brainstorming solutions, brainstorm all the ways to guarantee failure at this goal. List 10 ways to absolutely ensure [goal] never happens. Then, for each failure mode, identify the opposite action that would help succeed. This reveals blind spots and hidden assumptions.

I'm stuck on [problem] in [my industry]. Show me how 5 completely different industries solved analogous problems: for each, describe the industry, the analogous problem they faced, their solution, and specifically how I could adapt their approach to my situation. Industries to consider: [suggest or let AI choose surprising ones].

Apply the SCAMPER method to [product/service/idea]: Substitute (what components could be swapped?), Combine (what could be merged?), Adapt (what could be borrowed from elsewhere?), Modify (what could be enlarged/minimized?), Put to other use (how else could this be used?), Eliminate (what's unnecessary?), Reverse (what if you flipped the order?). Give 2 specific ideas for each letter.

Stress test this idea: [describe idea]. Play these roles: 1) The Optimist: best-case scenario and why this could be huge, 2) The Pessimist: worst-case scenario and what kills this, 3) The Pragmatist: what would actually happen step by step, 4) The Customer: honest reaction on hearing this pitch, 5) The Investor: what questions I'd ask. Be genuinely tough.
