Everyone is talking about AI, and most of the explanations are written for engineers or investors. This course is written for people who run businesses.

In six short lessons you'll learn what people actually mean by "AI", how tools like ChatGPT, Claude, Gemini and Copilot work under the hood, where they're genuinely useful, where they go wrong, and what happens to the information you give them. No jargon goes unexplained, and nothing here depends on which tool you use.

Each lesson ends with a five-minute exercise you can do in any AI chat tool, the mistakes people usually make, and three quick questions to check yourself.

You'll finish with: A clear picture of what today's AI tools can and can't do, and the questions to ask before you rely on one.
