The claim
“I made a prompt pack in an afternoon and it sells while I sleep.” Gumroad screenshots optional but implied. The entrepreneurial question isn’t whether files can be made — it’s whether strangers pay.
Our hypothesis
AI can create a credible digital good in one session. Distribution and trust decide sales. Free sample stays public; the $19 checkout is the real test now that Stripe Payment Links are live.
What we shipped
Viral Claim Auditor — a markdown prompt pack that stress-tests “make money with X” posts before you waste a weekend. Includes claim parsing prompts, a scoring rubric, and a one-page experiment brief template.
