Foodhak: Redesigning a D2C Personalised Nutrition AI App

The AI underneath Foodhak was brilliant and deeply personal, but its intelligence sat buried across five siloed tools, and nothing pulled you back to feed it. This case study covers rebuilding those five tools around that intelligence as one coach, Faye, the states designed for AI uncertainty, and the daily loop that keeps users feeding it, because the AI only gets smarter the more you use it.
