Claude Prompt for Brainstorming Ideas
Brainstorming is one of Claude's major strengths, capable of generating dozens of original ideas in seconds where a human team would take hours. Unlike a simple list of generic ideas, a well-structured prompt allows Claude to explore unexpected angles, cross different fields, and produce truly actionable concepts. Whether you are looking for product ideas, content ideas, marketing campaign ideas, or feature ideas, Claude excels when given a clear framework while still allowing creative freedom. The key lies in the combination of precise constraints (context, audience, objectives) and divergent thinking techniques (analogies, inversion, forced associations). By mastering brainstorming prompts, you turn Claude into a tireless creative partner that never judges, never self-censors, and can simultaneously explore conservative and radically innovative paths. This guide provides optimized prompts to get the most out of Claude's creativity, from quick brainstorming to structured sessions with multi-criteria evaluation.
Paste in your AI
Paste this prompt in ChatGPT, Claude or Gemini and customize the variables in brackets.
You are an expert brainstorming facilitator in creative thinking and innovation. I am working on the following topic: [DESCRIBE_YOUR_TOPIC_OR_PROBLEM].
Context: [INDUSTRY, TARGET_AUDIENCE, POSSIBLE_CONSTRAINTS]
Generate 15 ideas following this structure:
Block 1 — Safe Ideas (5 ideas): Proven, realistic, and quickly executable concepts.
Block 2 — Creative Ideas (5 ideas): Original approaches that combine elements from different fields.
Block 3 — Bold Ideas (5 ideas): Provocative, counterintuitive, or radically different concepts from what exists.
For each idea, provide:
- A catchy title
- A description in 2-3 sentences
- Estimated effort level (low / medium / high)
- Impact potential (low / medium / high)
End with a summary table ranking the 15 ideas by impact/effort ratio, and recommend the top 3 to start with.

Why this prompt works
This prompt leverages the risk-level brainstorming technique, which forces Claude to explore the entire creative spectrum instead of staying in its comfort zone. The block structure prevents the model's natural self-censorship, and the request for ranking by impact/effort ratio transforms a passive list into an actionable decision tool. The contextual framing (industry, audience, constraints) anchors ideas in project reality rather than producing generic suggestions.
Use Cases
Variants
Expected Output
You will get 15 ideas organized into three creativity levels, each with a memorable title, a clear description, and an effort/impact assessment. The final summary table lets you immediately identify quick wins and high-potential projects, with three priority recommendations to take action.
Frequently Asked Questions
How can I prevent Claude from generating overly generic ideas during a brainstorming session?
The key is to provide as much specific context as possible: your industry, your precise target audience, your real-world constraints, and especially what has already been tried or what your competitors are doing. Add an instruction like "Avoid obvious ideas you'd find on the first page of Google" or "Each idea must include an element that doesn't yet exist on the French market." The more precise your constraints, the harder Claude will have to work to find original angles.
How many ideas should I ask Claude for in an effective brainstorming session?
Ask for between 10 and 20 ideas per session. Below 10, Claude tends to stick to the obvious. Beyond 20, quality declines and ideas become redundant. The best approach is to request 15 ideas structured in blocks (safe, creative, bold), then iterate on the top 3-5 with a prompt like "Develop idea #X, detailing the implementation steps, risks, and success metrics."
Can Claude be used for collaborative team brainstorming?
Absolutely. The most effective method is to collect inputs from each team member (observed problems, hunches, known constraints) and integrate them into the prompt as context. Ask Claude to generate ideas that address each raised problem, then use the output as a basis for discussion in the meeting. You can also ask Claude to play devil's advocate on the team's favorite ideas to test their robustness before committing.
