# Artificial intelligence

> Software that learns to do a task from examples, instead of following step-by-step rules a person wrote by hand.

**Category:** Core concept

**Artificial intelligence is the broad umbrella term.** It covers everything from the spam filter in your inbox to the chatbot that drafts your emails. What unites them is the approach: instead of a programmer writing out every rule, **the system learns patterns from large amounts of data** and uses them to handle new cases.

In everyday use, "AI" usually means the helpful, **narrow kind that is good at one job**. It is *not* the all-knowing machine of the movies, and knowing that difference helps you judge what it can and cannot do.

## At work

Your inbox already runs on AI. The spam filter learned from millions of flagged messages what junk looks like, so most of it never reaches you, and you never had to write a single rule.

## Often confused with

Machine learning and generative AI. AI is the whole field; both of those sit inside it, not beside it.
