Help me test demand for a small service before spending time building it.
Service idea: {{idea}}
Specific buyer: {{buyer}}
Observed problem and evidence: {{evidence}}
Available time and resources: {{resources}}
Propose the smallest honest offer, five non-leading customer-interview questions, a manual pilot and a decision rule. Separate observations, assumptions and unanswered questions. Suggest what evidence would reject the idea, not only confirm it. Include a one-page outreach brief without fake testimonials or revenue promises. Do not assume that social-media interest equals willingness to pay.4 inputs still blank. Empty inputs stay as placeholders when copied.

Tips & limitations
The example is an editorial illustration, not a claim of platform-specific testing. Results depend on your inputs and model. Review factual claims before publishing or acting. Compatible platforms were selected from provider documentation; the example has not been re-tested on every platform. Features may require the relevant generation mode or account plan. Quality check: Interest, willingness to try and willingness to pay are separate observations.
