Why AI products need different design. A chat box is not a product. The real problems are specific: how a user starts when they do not know what to ask, how the system shows its reasoning without drowning them, what happens when the model is wrong, and how confidence gets communicated without either overclaiming or undermining the tool. I have solved these on an AI legal assistant handling sensitive case work, an AI learning platform serving three different user roles, and an AI market intelligence platform for ticketing brokers.
