Unknowns Narratives

Uncover insights and assumptions that you may have missed out on.

<p>I’m building [product or solution] for [target audience] to help with [problem or goal] using [unique feature, mechanism, or approach].</p> <p>Using this information, dig deep into my idea and approach. Identify any hidden assumptions, unknowns, or uncertainties I might be overlooking. Focus on things that could affect product-market fit, user behavior, adoption, or business model. Return a short analysis in clear, thoughtful language that surfaces 5 to 7 key points I should think about.</p>
Problem Snapshot

Turn a fuzzy hunch into a crisp “who / struggle / why-now” statement.

<p>I’m building a product for [target audience] who struggle with [the main challenge or frustration].</p> <p>Using this information, rewrite it into a sharp who / struggle / why-now statement. Keep it short and clear so it highlights who the user is, what their struggle is, and why solving it now matters. Make sure the statement flows and reads well.</p>
Zero-to-One vs. One-to-N

State whether this is invention or scale play and how that changes your idea and assumptions.

<p>I’m building a product that helps<br> [target audience]<br> [solve what problem or achieve what goal]<br> using<br> [product or approach]</p> <p>Using this information, tell me whether this idea is more likely a zero-to-one play (invention, creating something new) or a one-to-n play (scaling or improving something proven). Explain why, and highlight how that framing changes my assumptions, risks, and approach to execution.</p>
Bad Ideas Blitz

Generate 20 intentionally “bad” ideas to surface surprising good ones

<p>My interest area is [industry, theme, or topic, for example AI tools, healthcare, travel, education, social media]</p> <p>Using this, generate 20 intentionally bad, silly, or impractical product or business ideas in this space. They should be exaggerated, funny, or clearly flawed but still loosely related to the industry or theme. The goal is to break patterns, surface overlooked angles, and spark creative thinking.</p> <p>Return the list as plain text with each idea numbered from 1 to 20.</p>
First Principles

Reduce the problem to fundamentals and rebuild solution logic without unwarranted assumptions.

<p>The problem I’m working on is<br> [state the problem in one or two sentences]</p> <p>Using this, break it down into first principles by</p> <p>Stripping away assumptions and restating the problem in its most basic terms<br> Identifying the fundamental truths or constraints that are undeniably valid<br> Rebuilding the logic step by step into a solution approach that is free from unproven assumptions<br> Highlighting how this new framing changes or challenges my original perspective</p> <p>Keep the explanation clear, logical, and structured so I can see both the raw fundamentals and the rebuilt solution logic.</p>
Before/After Story

Generate two short paragraphs: life before vs. after your product.

<p>I’m building a product that helps<br> [target audience]<br> [solve what problem or achieve what goal]<br> using<br> [product or approach]</p> <p>Using this information, write two short paragraphs</p> <p>Paragraph 1: Describe the life of the target audience before using the product. Highlight the struggles, inefficiencies, or frustrations they face.</p> <p>Paragraph 2: Describe their life after using the product. Show how their experience improves, what outcomes they achieve, and why it feels like a meaningful transformation.</p> <p>Keep it simple, relatable, and emotionally engaging.</p>
Unbundle/Bundle

Determine what you’re unbundling or rebundling and the user barriers you remove.

<p>I’m building a product that helps<br> [target audience]<br> [solve what problem or achieve what goal]<br> using<br> [product or approach]</p> <p>Using this information, tell me<br> • What existing solutions or workflows this product is unbundling (breaking apart)<br> • What it is rebundling (combining into one place or flow)<br> • The main barriers or frictions for users that this approach removes<br> • Why this framing matters for positioning and go-to-market</p> <p>Keep the output concise and clear so I can quickly see how my product fits into the unbundle vs rebundle story.</p>
Wedge Selection

Choose a narrow, high-pain beachhead; define use case and why users would choose your product.

<p>I’m building a product that helps<br> [target audience]<br> [solve what problem or achieve what goal]<br> using<br> [product or approach]</p> <p>Using this information, identify<br> • A narrow, high-pain beachhead use case where adoption is most likely to start<br> • Why this wedge is critical and how it builds credibility or traction<br> • The main reasons users in this wedge would choose my product first over alternatives<br> • How solving this wedge use case creates expansion opportunities into adjacent markets or features</p> <p>Keep the output focused, specific, and actionable so I can clearly see where to start and why it matters.</p>
PESTLE “Why Now”

Generate 1-3 Political, Economic, Social, Tech, Legal, Environmental shifts that enable your idea.

<p>I’m building a product that helps<br> [target audience]<br> [solve what problem or achieve what goal]<br> using<br> [product or approach]</p> <p>Using this information, generate 1 to 3 relevant shifts in each PESTLE category that support why now is the right time for this idea</p> <p>Political<br> Economic<br> Social<br> Technological<br> Legal<br> Environmental</p> <p>Keep each shift short, clear, and directly tied to how it enables or accelerates adoption of my product</p>

Frequently Asked Questions

The Prompt Library is designed for early-stage founders, solo builders, and aspiring entrepreneurs who want to optimize their workflows and accelerate how they learn.

You can use ChatGPT, Claude, or Gemini. The choice depends on your personal preference and each works well.

Start by adding your chosen prompt and replacing only the required inputs highlighted in green. You can then customize it further based on the output you want or ask follow up questions after the initial answer is generated.

In most cases yes. However, large language models can sometimes produce inaccurate information called hallucinations. Always fact check important outputs before using them.
