Artificial intelligence (AI) is a broad name for computer systems designed to perform tasks that usually call for human abilities, such as recognising patterns, understanding language or making predictions. It is not one product or one kind of software.

AI is a field, not a single brain

Many modern products use machine-learning models trained to find patterns in examples. A generative model can create a new response—such as text, an image or code—based on what it learned and the instructions it receives. The response can sound confident without being correct.

What generative AI is useful for

Treat it as a collaborator for drafts, explanations, options and repetitive first passes. It can help you get unstuck or reorganise information. It does not automatically know your full context, check every source or take responsibility for a decision.

A useful way to try it

Give the tool a narrow task, relevant context and a clear output format. Ask it to show assumptions or cite material you supplied. Check important claims against primary sources, especially for health, money, law, safety, schoolwork and work decisions.

Try this: Ask an AI to explain a familiar topic in three ways: for a child, for a colleague and as a five-point checklist. Compare what changed and verify the facts.

A note on accuracy and privacy

Never treat generated content as proof that a claim is true. Avoid entering passwords, private customer records or confidential work material unless you understand the provider’s data settings and your organisation allows it.
