AI Prompts for ChatGPT for Brainstorming
20 of the best prompts for ChatGPT for brainstorming, step by step across 4 stages. Works with ChatGPT, Claude, and Gemini.
Use ChatGPT to run better ideation sessions: generate more ideas, develop the best ones further, stress-test them against reality, and use proven frameworks to decide which ones are actually worth pursuing. This guide walks you through every stage of ChatGPT for Brainstorming, from Frame the problem clearly all the way through Prioritise and plan next steps, with a curated, copy-ready prompt at each step. Each stage targets a specific phase of the process so you always know exactly what to ask and what output to expect. Works with ChatGPT, Claude, and Gemini and any other major AI tool.
Frame the problem clearly
The quality of ideas generated in a brainstorm is directly determined by the quality of the question asked. Reframe the problem before generating anything.
Reframe the problem
I want to brainstorm solutions to this problem: [DESCRIBE THE PROBLEM]. Before generating ideas, help me reframe it. What is the real problem underneath the stated problem? What are 3 different ways to define this challenge that might open up different solution spaces?
Write a how might we question
My problem is: [DESCRIBE]. Help me turn it into a set of "How might we..." questions that are specific enough to generate concrete ideas but open enough not to assume a solution. Give me 5 HMW questions at different levels of scope.
Identify the constraints
I am brainstorming solutions to [PROBLEM]. What constraints should shape my ideas: budget, timeline, team size, technical limits, or organizational reality? Help me name the real constraints so I generate ideas that could actually work.
Define what a good idea looks like
Before brainstorming solutions to [PROBLEM], help me define success criteria for an idea. What would a good idea need to: achieve, avoid, cost less than, and be feasible within? This will help me evaluate ideas rather than chasing every interesting option.
Map the problem space
Help me map the full problem space around [CHALLENGE]. What are all the dimensions of this problem: root causes, affected stakeholders, downstream effects, and the constraints that make it hard to solve? I want to understand the full space before narrowing to ideas.
Generate a wide range of ideas
Good brainstorming produces quantity first and quality second. Use these prompts to push past the obvious and find the ideas worth developing.
Generate 20 ideas
Generate 20 ideas for [DESCRIBE THE CHALLENGE OR OPPORTUNITY]. Include ideas that range from safe and incremental to radical and unconventional. Do not filter for feasibility yet. I want the full range. Flag the 3 you find most interesting and briefly explain why.
Generate ideas from unexpected angles
I have already thought of the obvious ideas for [CHALLENGE]. Help me generate ideas from unexpected angles: what would a competitor do, what would a child do, what would someone with unlimited budget do, and what is the exact opposite of the obvious solution?
Use a specific brainstorming framework
Use the [SCAMPER / SIX THINKING HATS / WORST POSSIBLE IDEA / RANDOM WORD STIMULUS] framework to generate ideas for [CHALLENGE]. Walk me through each element of the framework and give me 2-3 ideas from each angle.
Borrow ideas from other industries
What have other industries done to solve a problem similar to [DESCRIBE OUR CHALLENGE]? Give me 5 examples from industries completely different from [OUR INDUSTRY] and explain how the approach might translate to our situation.
Generate ideas for a specific constraint
Generate 10 ideas for [CHALLENGE] that work within this specific constraint: [DESCRIBE CONSTRAINT: UNDER $[X] budget / in [X] days / with a team of [X] / without any new technology]. The constraint is real and non-negotiable.
Develop and stress-test the best ideas
Most ideas need development before you can evaluate them properly. Use these prompts to build out the strongest candidates.
Develop a promising idea
I want to develop this idea further: [DESCRIBE THE IDEA]. Help me flesh it out: how would it actually work, who would it serve, what resources does it need, what are the key unknowns, and what would need to be true for it to succeed?
Challenge an idea you like
I am excited about this idea: [DESCRIBE]. Play devil's advocate. What are the strongest arguments against it? What assumptions am I making that might be wrong? What could go wrong that I am not seeing because I am too close to it?
Combine ideas
I have these promising ideas: [LIST 3-5 IDEAS]. Are there combinations that could be stronger than any single idea? What would a hybrid of [IDEA A] and [IDEA B] look like? What would each combination gain and lose?
Identify the key risks of each idea
Help me identify the key risks of each of these ideas: [LIST IDEAS]. For each idea, what is the biggest single reason it could fail? What assumption has to be true for it to work, and how confident am I that assumption holds?
Find the minimum viable version
This idea could be large and complex: [DESCRIBE]. Help me find the smallest, fastest version I could test to learn whether the core assumption is valid. What is the minimum viable version that gives me real signal without a large commitment?
Prioritise and plan next steps
A brainstorm that ends without a decision is just a meeting. Use these prompts to decide what to actually do.
Evaluate ideas against criteria
Help me evaluate these ideas: [LIST IDEAS]. Criteria: [DESCRIBE YOUR EVALUATION CRITERIA: IMPACT, FEASIBILITY, COST, SPEED TO TEST, STRATEGIC FIT]. Score each idea on each criterion and give me a ranked shortlist.
Build a prioritisation matrix
Plot these ideas on a 2x2 matrix of [IMPACT VS. EFFORT / STRATEGIC VALUE VS. FEASIBILITY / URGENCY VS. IMPORTANCE]: [LIST IDEAS]. Which quadrant does each fall into? Which ideas should I do now, plan for later, delegate, or drop?
Choose one idea to pursue
Based on my brainstorm, I am considering these top ideas: [LIST 3-5]. Help me make a decision. Given my constraints of [DESCRIBE CONSTRAINTS] and my goal of [DESCRIBE GOAL], which one should I pursue first and why?
Write a one-page idea summary
Write a one-page summary for this idea to share with [TEAM / STAKEHOLDERS / MANAGER]: [DESCRIBE THE IDEA]. Cover: the problem it solves, the proposed solution, key assumptions, resources needed, and suggested first step. Under 300 words.
Define the first three actions
I have decided to pursue this idea: [DESCRIBE]. What are the first three concrete actions I should take in the next [WEEK / TWO WEEKS] to move it forward? Make each action specific, time-bound, and something one person can own.
Frequently asked questions
What makes ChatGPT useful for brainstorming versus just thinking it through yourself?+
Speed and range. ChatGPT generates more options faster than most individuals or teams can, and it does not have the same cognitive biases toward familiar ideas. It is also a useful mirror. Describing your problem to get ideas from it forces you to articulate what you are actually trying to solve, which often clarifies your own thinking.
How do I avoid ChatGPT just giving me generic ideas?+
Give it a specific, well-framed problem. The more context you provide, including your constraints, your target customer, and what you have already tried, the more relevant the output. Also ask it to go beyond the obvious: explicitly tell it you want unconventional ideas, or ask it to borrow approaches from completely different industries.
Should I use ChatGPT for brainstorming alone or with a team?+
Both work. Solo, use it to generate a wide range of ideas before a team session so you arrive with raw material to react to. With a team, use it live to inject unexpected options when the group gets stuck or converges too early. It is most powerful as a stimulus for human discussion, not a replacement for it.
How do I evaluate which ideas from a brainstorm are actually worth pursuing?+
Define your evaluation criteria before generating ideas, not after. Criteria like impact, feasibility, cost, and speed to learn give you a consistent framework. Use ChatGPT to score ideas against criteria or build a prioritisation matrix. The goal is a decision, not a longer list.
What is the most common brainstorming mistake?+
Evaluating ideas while generating them. The moment someone says "that will not work," the group stops generating freely. Keep generation and evaluation as two separate phases. Use ChatGPT to generate broadly first, then switch to evaluating the shortlist with a clear set of criteria.
