Great AI is invisible when the experience is right. Users do not care which model you chose; they only care that the interface feels intuitive, trustworthy, and fast. That means pairing prompt engineering with classic UX work: clear hierarchy, guidance, feedback, and graceful failure states.
Every intelligent feature needs a story: what it knows, what it can decide, and what the user controls. When you design these boundaries deliberately, AI augments users instead of confusing them.
