Two uses: infrastructure and material
Design infrastructure and product material.
As infrastructure, it sits behind the work and never shows up in the interface. It summarizes a round of interviews, writes down a system exception so engineering does not depend on my memory, and drafts the note in which business and design see the same decision. The point is to reach the decision sooner, and for the team to share the criterion.
As a design material, AI is what the person uses. Without it the product does not exist: there are no transactions to classify, no contract to flag, no text to draft from an offer. Designing there means deciding what the model does, what the person confirms, and what happens when the model does not know. The projects below sit in this second category.
