MealMind

Meal-planning apps fail because they ask too much: browse a thousand recipes, set twenty dietary toggles, build the grocery list yourself. MealMind asks one question — how's your day looking? — and infers the rest: three meals matched to your energy and schedule, a deduplicated grocery list, substitutions, and a budget estimate.

It's really a product-psychology experiment wearing a cooking app's clothes: one input kills decision fatigue, the early budget figure is a deliberate anchor, and a checkable grocery list exploits completion bias. Built for the PromptWars hackathon; the AI does the inferring so the user never fills out a form.
