The product is not the prompt box. The product is what gets accomplished after the user arrives.
The first generation of many AI products made model access the center of the experience: open a chat interface, enter a prompt, receive a response, and decide what to do with it.
That interface is powerful because it exposes a general capability. But many business problems are not general. They have known inputs, data sources, rules, review requirements, systems, users, and definitions of completed work.
When those conditions exist, product design can move beyond providing access to intelligence and begin engineering the complete workflow around it.
The result is less about asking AI to help and more about building software that uses intelligence to complete a defined part of the work.
