Every software company has started calling its product an "AI agent." That makes it hard to tell what you're actually buying, or whether you need one at all. This guide strips the word down to what it really means, so you can spot real value and skip the hype.

The short version

A chatbot answers. An agent acts.

You ask a chatbot a question and it writes an answer. You give an agent a goal, and it works out the steps, uses tools (your email, calendar, a spreadsheet, a website), checks its own work, and comes back with something finished, or asks you before doing anything that matters.

That's the whole difference. Same kind of AI underneath. What changes is that the agent is allowed to take steps.
