Gemini Prompt for Brainstorming Ideas
Brainstorming is a crucial step in any creative, strategic, or entrepreneurial project. Yet, generating original and relevant ideas remains a challenge, especially when working alone or running in circles on a topic. Gemini, Google's artificial intelligence model, excels at idea generation thanks to its ability to cross-reference various fields of knowledge and propose unexpected angles. Unlike classic brainstorming where cognitive biases often limit exploration, Gemini can traverse a much wider space of possibilities in a few seconds. Whether you're looking for content ideas, product concepts, brand names, marketing angles, or solutions to a complex problem, a well-structured prompt turns Gemini into a tireless thinking partner. The key is not simply to ask for ideas, but to frame the request to obtain diversified, actionable proposals aligned with your real constraints. The prompts presented here use proven techniques to maximize the quality and variety of generated ideas, guiding the model towards methodical exploration rather than just a generic list.
Paste in your AI
Paste this prompt in ChatGPT, Claude or Gemini and customize the variables in brackets.
You are an innovation director specializing in structured creativity. I am working on the following topic: [DESCRIBE_YOUR_TOPIC_PROBLEM_IN_DETAIL].
My context: [INDUSTRY_SECTOR_TARGET_AUDIENCE_POTENTIAL_CONSTRAINTS].
Generate 15 ideas using this method:
- 5 conventional ideas: proven and realistic approaches in my field, easy to implement quickly.
- 5 ideas by analogy: draw inspiration from solutions that work in other sectors (tech, art, nature, sports, gastronomy) and transpose them to my context.
- 5 disruptive ideas: bold proposals that challenge the conventions of my sector, even if they seem risky.
For each idea, provide:
- A catchy title
- A 2-3 sentence description
- The implementation difficulty level (easy / medium / hard)
- The estimated impact potential (low / medium / high)
Finish with a summary table ranking the 15 ideas by impact/difficulty ratio, from the most promising to the lowest priority.

Why this prompt works
This prompt leverages three key prompt engineering techniques: role-playing (innovation director) which activates a specialized creative register, forced categorization (conventional, analogy, disruptive) which prevents the model from staying in a single comfort zone, and output structuring that ensures actionable rather than vague ideas. The request for a summary table forces a comparative evaluation that aids immediate decision-making.
Use Cases
Variants
Expected Output
You will receive a structured list of 15 ideas divided into three levels of boldness, each accompanied by a title, a concrete description, and a difficulty/impact assessment. The final table will allow you to quickly identify the 3 to 5 most promising ideas to explore first, with a clear vision of the effort required for each.
Frequently Asked Questions
How can I prevent Gemini from generating overly generic ideas during a brainstorming session?
The key is to provide rich context and specific constraints in your prompt. The more precisely you describe your industry, audience, resources, and what has already been tried, the more targeted ideas Gemini will produce. Add instructions like 'avoid obvious suggestions' or 'propose angles my competitors likely aren't using.' You can also ask Gemini to justify how each idea differs from conventional approaches in the sector.
Can Gemini be used for collaborative team brainstorming?
Absolutely. One effective method is to use Gemini as a starting point: each team member submits their own prompt with their constraints, and then you consolidate the results. You can also ask Gemini to play multiple roles (marketer, engineer, end user) to simulate different perspectives. Finally, after the first round of generation, share the shortlisted ideas and ask Gemini to combine, improve, or challenge them to enrich the team discussion.
How many brainstorming rounds should you do with Gemini to get good ideas?
Generally, two to three iterations are enough for a productive brainstorming session. The first round generates a broad range of ideas. The second round refines them: ask Gemini to dive deeper into the 3 to 5 most promising ideas, combine them, or adapt them to additional constraints. An optional third round can be used to stress-test the finalists by asking Gemini to identify each idea's weaknesses and propose solutions. Beyond three rounds, you risk going in circles—start prototyping instead.
