What Is an AI Agent?

An AI agent is an AI system that can pursue a goal by planning steps and taking actions, rather than only answering a single message. It typically uses a language model to decide what to do next and can call tools — such as search, calculators, or other software — then use the results to continue.

AI Agent vs. Chatbot

A chatbot mainly responds in conversation. An agent can carry out multi-step tasks, for example gathering information, filling in a spreadsheet, and summarizing results, often with human review at key points.

Automation and Oversight

Because agents act on the user’s behalf, they are usually given limited permissions and are monitored, so that mistakes can be caught before they have consequences.
