Browse the best AI prompts for Brainstorming. All tested and copy-paste ready.
Brainstorming with AI is fundamentally different from brainstorming alone. AI never gets stuck on the first idea, never anchors to the obvious, and never runs out of variations. These prompts cover the four phases where AI adds the most value: generating ideas from scratch, expanding and building on a starting point, stress-testing ideas before committing, and running structured sessions for specific contexts like naming, strategy, and content.
Stage 1
The blank page is where most people get stuck. These prompts break through the starting block and produce a large raw set of ideas to work from.
Generate 20 ideas on a topic
Generate 20 different ideas for [DESCRIBE TOPIC OR CHALLENGE]. Cover multiple approaches: obvious and unexpected, simple and ambitious, short-term and long-term. Do not evaluate or filter yet. I want volume. Label each idea with one word describing its type or angle.
Brainstorm from a different perspective
I am trying to generate ideas for [DESCRIBE CHALLENGE]. I keep coming up with the same obvious answers. Approach this from the perspective of [CHOOSE: a competitor, a customer, a total outsider, a five-year-old, a contrarian]. Give me 10 ideas from that perspective that I would not have come up with myself.
Generate ideas using random constraints
Generate ideas for [DESCRIBE PROBLEM] with these constraints: [ADD 2-3 CONSTRAINTS, e.g. must cost under $100, must work without internet, must take under 10 minutes]. Constraints often force the most creative solutions. Give me 10 ideas that work within all the constraints.
Brainstorm problems before solutions
Before I try to solve [DESCRIBE AREA OR GOAL], help me brainstorm all the problems and friction points involved. List every obstacle, frustration, gap, or unmet need you can identify. Then mark the top three that, if solved, would have the biggest impact. I want to find the right problem before jumping to solutions.
Generate ideas across categories
Generate ideas for [DESCRIBE CHALLENGE] across these categories: [LIST 4-5 CATEGORIES, e.g. product, marketing, operations, team, partnerships]. Give three ideas per category. Some of the most useful ideas come from transferring solutions from one category to an unexpected one.
Stage 2
One good idea is a starting point. These prompts develop a concept into something complete, concrete, and ready to act on.
Develop a rough idea into a full concept
Here is a rough idea: [DESCRIBE IDEA IN ONE OR TWO SENTENCES]. Develop it into a fully fleshed-out concept. Include: what it is and how it works, who it is for and what problem it solves, what would make it succeed, and three variations or directions it could go. Make it concrete enough to pitch or test.
Find 10 ways to make an idea better
Here is an idea I am working on: [DESCRIBE IDEA]. Give me 10 specific ways to make it stronger, more original, more useful, or easier to execute. Do not just say "add more features" or "improve the UX." Be specific about what to change and why it would make the idea better.
Generate names or titles for a concept
I need a name or title for [DESCRIBE WHAT YOU ARE NAMING: product, project, article, event, feature]. It should [DESCRIBE KEY QUALITIES: be memorable, suggest speed, feel premium, be easy to spell, work in multiple languages, etc.]. Generate 20 options. Include a mix of: descriptive names, invented words, metaphorical names, and acronyms. Mark your top three with a reason.
Map out all the components of an idea
Here is an idea: [DESCRIBE IDEA]. Break it down into all the components needed to make it real. What are the moving parts: the people, processes, technology, content, partnerships, and resources involved? Build a mind-map style breakdown of everything that would need to exist for this to work.
Find the most interesting version of an idea
Here is a straightforward idea: [DESCRIBE IDEA]. Push it to be more interesting. What is the most creative, unexpected, or counterintuitive version of this? What is the boldest possible execution? Give me three directions: one that is slightly bolder than my original, one that is a significant departure, and one that is completely unexpected.
Stage 3
Generating ideas is the easy part. Knowing which ones to pursue requires honest evaluation. These prompts pressure-test ideas before you commit time or money.
Find the weaknesses in an idea
Here is an idea I am excited about: [DESCRIBE IDEA]. Act as a skeptic and find every weakness. What are the strongest arguments against it? What assumptions is it built on that might be wrong? What could go wrong in execution? What would a smart critic say? Do not be gentle. I need to know the real objections before I commit.
Compare multiple ideas and pick the strongest
I have the following ideas and need to choose one to pursue: [LIST IDEAS]. Evaluate each against these criteria: [LIST CRITERIA, e.g. feasibility, cost, time to execute, likely impact, originality]. Give each a rating and a one-sentence verdict. Then tell me which one to pursue and why, and what the main risk of that choice is.
Pre-mortem: why this idea will fail
I am planning to pursue this idea: [DESCRIBE IDEA]. Fast-forward 12 months. The idea has failed. What went wrong? List the most likely causes of failure, ranked by probability. For each one, tell me what I could do now to prevent it. This is a pre-mortem, not a reason to stop — it is a way to plan better.
Identify assumptions that must be true for this to work
Here is my idea or plan: [DESCRIBE]. What are the core assumptions I am making that must be true for this to succeed? List them in order from most to least critical. For each one, tell me: how confident I should be that it is true, and how I could test or validate it cheaply before committing fully.
Rate ideas on effort versus impact
Here is a list of ideas or options I am considering: [LIST IDEAS]. For each one, estimate: the effort required (low, medium, high), the potential impact if it works (low, medium, high), and the risk if it fails (low, medium, high). Then tell me which two to prioritize based on the highest impact-to-effort ratio, and which one to skip.
Stage 4
Different brainstorming contexts need different approaches. These prompts are designed for the most common high-stakes brainstorming situations.
Brainstorm content ideas for a week
I create content about [TOPIC OR NICHE] for [AUDIENCE]. Brainstorm a full week of content ideas: one main piece and three shorter pieces for each day. Each idea should be: specific enough to start writing immediately, tied to something my audience genuinely cares about, and varied enough that the week does not feel repetitive.
Brainstorm solutions to a business problem
My business is facing this problem: [DESCRIBE PROBLEM]. Generate 15 possible solutions across different approaches: quick fixes, structural changes, technology solutions, people solutions, and partnership solutions. For each one, give me a one-sentence description and the main risk or downside of that approach.
Brainstorm questions to ask before making a decision
I am about to make this decision: [DESCRIBE DECISION]. Before I decide, what are all the questions I should be able to answer? Brainstorm every question that would give me information I need, including questions I might be afraid to ask or might not have thought of. Organize them by category: financial, people, risk, timing, and strategic fit.
Generate angles for a presentation or pitch
I need to build a presentation about [TOPIC] for [AUDIENCE]. Brainstorm 10 different angles or narratives I could take. Each angle should be a different way of framing the same underlying content. Which angle would be most persuasive for this audience? Which would be most memorable? Mark your top two and explain why.
Brainstorm product or service features
I am building [DESCRIBE PRODUCT OR SERVICE] for [TARGET CUSTOMER]. Brainstorm features and improvements across three lists: must-have features that solve the core problem, nice-to-have features that increase value, and surprising or delightful features that would make customers tell others about it. For each category, give me at least five specific ideas.
Add constraints and perspectives. Telling AI to brainstorm from the perspective of a customer, competitor, or outsider produces ideas you would not generate yourself. Adding unusual constraints forces creative problem-solving. Generic prompts produce generic ideas; specific framing produces specific results.
Start with volume, not quality. Ask for 20 ideas, not the best idea. The first ideas are always the obvious ones. By the time you reach idea 15 or 20, AI has exhausted the expected answers and starts producing more interesting ones. Then evaluate the list and pick the three worth developing further.
Tell it explicitly what you do not want. If you are brainstorming marketing ideas, say "exclude social media posts and email newsletters." Or ask for the opposite: "what would a company that hates conventional marketing do?" Telling AI what to avoid is as powerful as telling it what to produce.
No, but it can make the team session better. Use AI before the meeting to generate a starting list that removes the blank-page problem. Use it after to expand on the ideas the team developed. The combination of human context and AI volume produces better results than either alone.
More than you think you need. Ask for 20 and you will use three. The discipline of generating volume forces AI past the obvious answers. Asking for "the best idea" produces a safe, mediocre answer. Asking for 20 and then evaluating them yourself produces much better outcomes.
