A fixed four-part research prompt, run in two models
how-toClaude's insight: "The real competitor isn't another expense app. It's doing nothing."
Only the product-and-audience sentence changes between projects ("an expense management app for families and students who want to optimize their spend"). ChatGPT returned personas like Priya (family planner), Rohan (student who runs out by the 20th) and Sunita (semi-retired), and the insight that users want "permission to spend without guilt"; Claude stressed capturing expenses within the first 48 hours of onboarding. Merge the best of both; the trainer then sticks with Claude as "really robust".
A repeatable research starter that keeps outputs comparable.
