What is Artificial Intelligence?
A plain-English introduction to what AI means and what it can do.
Artificial Intelligence (AI) is technology that lets computers perform tasks that normally need human thinking — like understanding language, recognising images, making decisions, or solving problems.
You do not need to understand the maths behind it. Think of AI as software that can learn patterns from data and use those patterns to help you. When you ask Siri a question, get movie recommendations on Netflix, or use ChatGPT to draft an email, you are using AI.
AI is not one single thing. It is a broad field that includes many different approaches and tools. Some AI follows fixed rules; more modern AI learns from examples.
Examples
- •A spam filter that learns which emails are junk
- •A navigation app that predicts traffic and suggests faster routes
- •A chatbot that answers customer questions on a website
- •An AI assistant that helps you write or summarise documents
Key points
- ✓AI lets computers handle tasks that usually need human thinking
- ✓You already use AI in everyday apps and services
- ✓AI is a broad field, not a single product
- ✓Modern AI often learns from data rather than following fixed rules
