NineFengShui is an AI-assisted feng shui analysis web app that lets users map their home onto a 3×3 bagua grid, set direction, label rooms, and generate a personalized Assessment Report or full Remedy Report. It combines a traditional feng shui rule engine with AI-powered report formatting, and supports English, Simplified Chinese, and Spanish.
