What an AI agent is in a small company
An AI agent is a workflow that chooses between defined steps and tools, depending on the case in front of it. In n8n, for example, the AI Agent node works with a chat model and at least one tool, and the agent decides which tools to call. That choice is the difference to a fixed automation, which runs the same steps every time.
Most useful agents in an SME do one job: they receive an enquiry, a document or a question, choose which tools they need, prepare a result and hand it to a person. They are not digital colleagues with general responsibility. The value comes from the limits, not from autonomy, because a narrow agent can be tested and trusted. Our step-by-step guide shows such an agent: building an AI agent with n8n that sorts enquiries and prepares a reply for approval.
