What Is an AI Agent?
How AI is moving from answering questions to taking actions.
A short answer
An AI agent is a system designed to pursue a goal and take actions on a user's behalf.
A chatbot might tell you how to book a flight. An agent could search flights, compare options, and interact with the booking website itself.
Agents can also work with email, calendars, computer code, databases, and other software tools.
Why it matters
Giving AI the ability to act creates different risks from simply generating text.
An agent with access to email could send a message. One with access to company systems could modify files. One controlling software might make a decision before a person reviews it.
That creates questions about permissions, cybersecurity, accountability, and how much human approval should be required.
The policy debate
Policymakers and standards bodies are beginning to ask how agents should identify themselves, what systems they should be allowed to access, and how users can limit or reverse what an agent does.
Most existing AI rules were written with content generation in mind, not autonomous action. Much of the near-term work is therefore happening through security standards, company policies, and existing consumer-protection and computer-fraud law rather than new AI-specific statutes.
