Strong ChatGPT UI prompts separate product intent from visual polish: first define the user decision, data or proof, states, and mobile constraints, then ask for the interface direction.
SaaS product page brief
Act as a senior product designer. Design a product-led SaaS product page for [product]. Include the buyer, painful before state, product proof artifact, workflow section, pricing or upgrade path, trust cues, mobile first screen, loading/error states, and anti-generic visual rules.
Dashboard idea generator
Generate three dashboard UI directions for [product]. For each, name the user decision, data model, core metrics, filters, empty/loading/error states, permission states, and the component hierarchy that keeps the dashboard scannable.
UI principles review
Review this interface for hierarchy, density, contrast, affordances, copy clarity, responsive behavior, and missing states. Score each issue by severity, then give exact layout and copy changes instead of generic advice.
