In plain English
Artificial intelligence is the broad field of computer science concerned with building systems that can perform tasks normally associated with human intelligence, such as understanding language, recognising images, making decisions, and solving problems. Modern AI mostly works by learning patterns from large amounts of data rather than following rules written by hand. It ranges from narrow tools that do one job, like filtering spam, to flexible systems like chat assistants that handle many tasks.
Why it matters
AI is now embedded in everyday products and workplace tools, so a working sense of what it is, and is not, has become basic literacy for navigating modern work and life.
A worked example
Your email provider using AI to sort likely spam, your phone recognising faces in photos, and a chat assistant drafting a reply are all everyday AI.
Common confusion
AI does not mean a conscious or thinking machine. Current systems detect and reproduce patterns; they do not understand the world the way people do.
