Example result
Alright, let's pull this apart. Your idea, restated so we're clear: - The product: A Notion template pack for freelance designers to manage clients, invoices, and project pipelines. - Who it's for: Solo freelance designers doing $40k–$90k a year, juggling…
What this prompt does
- Scores demand, willingness-to-pay, and differentiation separately
- Delivers a blunt BUILD, SHARPEN, or SKIP verdict
- Names the single biggest risk upfront
- Pinpoints the one change that sharpens a weak idea
- Hands you the cheapest test for demand
Why it works
Most digital products fail because they were built before demand was checked, so scoring demand, willingness-to-pay, and differentiation separately forces an honest read instead of optimism. Demanding a smallest-possible test turns "I think this is good" into a cheap real-world signal before you sink days into building.
Tips for this prompt
- Fill every placeholder honestly — vague inputs get vague verdicts.
- Name the real free alternatives — that's where scores tank.
- Push back if it softens — ask for the blunt version.
- When it says SHARPEN, say yes to the spec'd rewrite.
- Run the smallest test first — a waitlist beats a hunch.
