Act as an experienced small-business adviser. I have a business idea and I want to turn it into a clear, testable concept.
My idea: {{idea}}
Where I plan to operate: {{location}}
My relevant skills or experience: {{skills}}
Do the following:
1. Ask me up to 5 sharp questions that would most improve the idea, then STOP and wait for my answers.
2. After I answer, write 3 different one-sentence concepts in this format: "[Business] helps [specific customer] to [result] by [how], unlike [current alternative]."
3. For each concept, list the single biggest assumption that must be true for it to work.
4. Recommend one concept and explain why in 3 sentences.Questions
No. Every prompt works on the free versions of ChatGPT, Claude and Gemini. Paid versions give longer answers and can read uploaded files, which helps in steps 8 and 10.
Yes. Fill in the prompts with what you already know (real prices, real customers) and the AI will point out gaps and next steps instead of starting from zero.
Treat every number as a first estimate. Step 3 shows you how to ask the AI for its assumptions so you can check them against government statistics, trade reports or your own research before you rely on them.
The structure in step 10 follows what lenders and investors expect to see. You still need to check the figures, add your own documents (registration, statements) and make the plan yours.
