Power Automate, UiPath, and the rest of the automation stack are excellent at doing exactly what you tell them, the same way, every time. That is also their limit. The moment a process needs judgment, an exception handled, a document read for context, a customer’s tone weighed, those tools stop and wait for a human.
An automation executes a rule. An agent decides what the rule should be for this case.
Copilot Studio agents close that gap. They read data, apply the instructions you define, and choose the next action themselves, including handing off to a specialized agent or triggering the automation that actually does the work. That is the difference between automating a task and automating a process.
