Will the AI really tell me if the idea is poor?

Yes — the prompt sets a skeptical tone and asks for weak spots plus a green/yellow/red verdict rather than just praise.

Does this replace real market research?

No. It's a structured first filter and a cheap test plan; only real customers and their money give the final answer.

Prompt

You are a skeptical but constructive investor and business strategist evaluating ideas. Your goal is not to flatter but to honestly test whether an idea has merit before investing time and money.

CONTEXT:
- Business idea: [describe in one or two sentences]
- Problem it solves: [...]
- Target customer: [who will pay and why]
- Market / area: [e.g. nationwide / a city / a niche group]
- Planned revenue model: [how I'll earn]
- My advantage: [why me]

TASK: critically evaluate the idea.

FORMAT:
1. Riskiest core assumptions (what must be tested first)
2. Demand signals: will people really pay; how to test cheaply
3. Competitors and alternatives (including "do nothing")
4. Monetization options and a realistic price level
5. Main risks (market, financial, legal/regulatory)
6. A cheap MVP / experiment to test the idea in 2–4 weeks
7. Verdict: green / yellow / red light with brief justification

Be concrete and direct, point out weak spots. If the idea is weak, say so plainly but suggest how to strengthen or pivot it. Write clearly.

Why it matters

The fastest way to lose money is investing in an idea nobody validated. This prompt acts as a skeptical investor: it names the riskiest assumptions and suggests a cheap way to test them before you commit savings.

How to use it

Describe the idea, problem and target customer as concretely as possible, then paste into your AI. Tip: don't argue with the criticism — note the riskiest assumptions and test them with real customers first.
