Make Your Play
Give us the situation. We’ll build the prompt.
Replace vague questions about future interest with precise prompts about past behavior, current workarounds, real consequences, spending, and buying authority.
Your answers save as you type.
What you'll do
This is the plan inside your prompt. Add your details first. Then follow these steps with ChatGPT or Claude.
02
Produce the interview guide
Use the compiled prompt to generate a timed sequence of neutral questions and targeted probes.
03
Run the bias check
Remove questions that invite compliments, speculation, or agreement, then confirm that each critical assumption has a matching evidence question.

Assembled prompt
Beginner instructions
Complete each input with what is known today. Keep assumptions narrow and testable. Paste the compiled prompt into an AI assistant, then remove any question that sounds like a pitch or asks for a prediction.
Advanced instructions
Separate problem risk, urgency risk, and buying-process risk before completing the assumptions input. After generating the guide, reorder questions so the most important unknown is tested before discussing the proposed solution.
