AI step vs. AI agent
A simple AI step in a workflow does one specific job — classify this message, summarize this document. An AI agent goes a step further: it can decide, within limits you define, which tools or actions to use to complete a broader task.
What that looks like in practice
A WhatsApp AI agent connected to a knowledge base might decide on its own whether a customer's question can be answered directly from your documents, needs a lookup in your order system, or should be escalated to a person — rather than following one fixed path every time.
Why this needs careful design
Giving an agent more autonomy means being deliberate about what tools and data it can access, and building in clear fallback behavior for anything it isn't confident about. A well-designed agent workflow always has a defined path for escalating to a human.
Where agents make sense today
Customer support and internal knowledge lookup are currently the most practical, lower-risk places to introduce an AI agent, since the cost of an uncertain answer is low if it's simply escalated rather than acted on directly.
