An AI agent is a system that can autonomously perceive inputs, plan a sequence of actions, use external tools (APIs, databases, browsers), and iterate toward a stated goal.

Unlike a simple chatbot that responds to prompts, an agent maintains state across steps, decides what to do next, and can trigger real-world actions.

In marketing, agents are being used to automate research, content drafting, campaign QA, and reporting workflows.
