What a chat AI is, in one picture

Module 1: Your first 10 minutes with AI

Course outline

Quick check

Guess first, no penalty. How does an AI chat app write its answers?

A chat AI is an app you write to, and it writes back. AI means artificial intelligence: computer programs that can do tasks like writing. ChatGPT, Gemini and Copilot (three free chat AI apps) all work this way. If you can send a WhatsApp message, you can use one.

Why it can be wrong

Your phone keyboard suggests the next word as you type. A chat AI does something like that, much bigger. It learned from a huge amount of text, so it writes what sounds right. It doesn't always check if it is true.

So it's strong at words, and weak at exact facts like numbers, dates and today's news.

      A chat AI is an app that writes answers to your messages. It's fast and helpful, but it can be wrong, so you check anything important.

      You ask a chat AI when the job centre near you opens. It answers "9 am to 5 pm" and shows no source. You plan to go tomorrow. What do you do first?
