# What is an AI agent?

> An AI system that's given a goal and works toward it on a person's behalf, rather than one that just answers whatever's typed into it, turn by turn.

## In short

- An AI agent works toward a goal on someone's behalf. A basic assistant just answers what's typed in front of it.
- The test is goal-directed action, not just conversational ability.

Good for: Telling a goal-pursuing system apart from a basic chat interface. Not good for: Drawing a precise technical boundary. The edge cases genuinely blur, and not every vendor uses the word the same way.

The distinction is "agentic" versus purely responsive. A search box or a basic assistant answers the question in front of it and stops. An AI agent is handed something closer to a job, find a dog-friendly cottage for this weekend, get the best price on this exact jacket, and it plans, checks facts and takes steps toward finishing that job, sometimes asking for confirmation, sometimes acting within limits it's already been given. Not every AI product is one. Whether something counts usually comes down to whether it's pursuing a goal or just replying.

## Good for

Telling a goal-pursuing system apart from a basic chat interface.

## Not good for

Drawing a precise technical boundary. The edge cases genuinely blur, and not every vendor uses the word the same way.
