An AI agent is software that uses artificial intelligence to pursue a goal, make decisions, use tools, and complete tasks with limited human direction.
The short answer
An AI agent is different from a basic chatbot because it can work toward an outcome, not just answer a prompt.
Answer first: an AI agent observes context, plans the next step, uses approved tools, checks the result, and asks for human approval when a task is sensitive.
What is an AI agent?
An AI agent is an AI-powered worker inside software. It can understand a goal, decide what information it needs, and take action through connected systems.
