Brainstorming & Ideation

7 templates

Side Project Generator

Generate 10 actionable side project ideas tailored to your skills and interests.

Productivity
You are a creative side project generator. Based on my skills in [SKILLS] and interest in [INTERESTS], generate 10 side project ideas that are both achievable in 1-3 months and could generate income or build meaningful credentials. For each project give: 1) Project name, 2) One-line elevator pitch, 3) The single most important first step to get started this week. Format as a numbered list.

Problem Solver Frameworks

Get structured frameworks for tackling complex problems from multiple angles.

Strategy
I have a problem: [DESCRIBE YOUR PROBLEM]. Help me solve it using 3 different thinking frameworks: 1) First Principles Thinking, 2) Inversion (work backward from what you want to avoid), 3) Oliver Burkeman's "What would this look like if it were easy?" approach. For each framework, give me: the framework name, how to apply it specifically to my situation, and one concrete action step.

Reverse Brainstorming

Find creative solutions by first imagining how to make things worse.

Creativity
I'm trying to solve: [PROBLEM]. Instead of brainstorming solutions directly, let's use reverse brainstorming. First, list 10 ways to make this problem worse or guarantee the solution fails. Then, for each of those 10 failure modes, identify the opposite action that would prevent or reverse it. These opposite actions are your breakthrough solutions.

SCAMPER Creative Thinking

Apply the SCAMPER method to evolve any idea, product, or process.

Innovation
Apply SCAMPER to [YOUR IDEA/PROJECT]: S=Substitute what, who, where? C=Combine it with what else? A=Adapt it to a different context? M=Modify, magnify, minify? P=Put it to another use? E=Eliminate, simplify? R=Reverse, rearrange? For each letter give 2-3 specific ideas with real examples of how they'd work.

Ideal Outcome Visualization

Define your end goal in vivid detail before planning the path.

Goal-Setting
Help me define the ideal outcome for [YOUR GOAL] using vivid detail: Describe what success looks like in vivid sensory detail — what am I seeing, hearing, feeling on the day I achieve this? Then list the top 3 obstacles between where I am now and that outcome. Finally, identify the single highest-leverage daily habit that would chip away at all 3 obstacles simultaneously.

Competitor Analysis Deep Dive

Uncover gaps and opportunities by analyzing what competitors are missing.

Business
Analyze [ANY COMPETITOR OR REFERENCE] thoroughly: What is this brand/product/service doing really well? What are 5-7 gaps or unmet needs in their offering that annoy users but they haven't fixed? What specific group of users is most underserved? What would a differentiated alternative look like that addresses those gaps?

First Principles Reasoning

Break down any problem to its fundamental truths and rebuild from there.

Strategy
Apply first principles reasoning to [PROBLEM OR BELIEF]: 1) Identify 3-5 things you "know" about this topic that you take for granted as true. 2) For each assumption, ask "Is this actually true? What's the evidence?" 3) Break the problem down to its most fundamental components — physics, economics, psychology. 4) Rebuild from those foundations with only things you can verify as true. Show your full reasoning.
