What are AI agents?

5 min read

The simple version

When you ask ChatGPT to write an email, you're using a tool. You give it a task, it gives you a result, you move on.

An agent is different. You give it a goal — "research my competitors and draft a strategy" — and it figures out the steps itself. It might search the web, read documents, write notes, revise its thinking, and deliver a finished report. You review the output, not every micro-decision.

Why this matters for your workflow

Tools save you time on individual tasks. Agents save you time on entire workflows. The difference is who's driving — with a tool, you are. With an agent, it is.

Think of it like hiring: a tool is a freelancer you give specific instructions to. An agent is an employee you give a goal to and trust to figure out the details.
