The most useful AI products are no longer just chat interfaces. They are workflow systems where a model can decide what context it needs, call a tool, ask for approval, and hand work to another specialised agent.
For mobile and web apps this changes product design. The best user experience is not an oversized text box. It is a small set of high-confidence actions: draft a document, compare options, prepare a support reply, create a learning plan, or run a safe business task.
Teams should start with narrow agents that have clear permissions, observable traces and human checkpoints. The value is not magic autonomy. The value is removing repeated coordination work while keeping the user in control.
