Before we look at a single AI tool, let’s set you up to get the most out of this course. In a few minutes you will know exactly where we are headed, how you will practice, and how to make every chapter pay off. Let’s start with the big picture.
Before we talk about AI tools, here are the three ideas that will guide you through the whole course:
Understand how to phrase a clear request, so you get a result that matches what you actually wanted.
Know what to hand off to AI, and how far you should stay involved.
Adjust how much you check depending on the situation, so you keep control and decide when to verify, correct, and own the result.
In short, this course teaches you to collaborate with AI and use it as a real copilot in your day-to-day work.
This course was created by the OpenClassrooms Team with the help of artificial intelligence.
To learn fast, nothing beats practicing on a concrete case. So throughout the course, you will apply every idea to a single hands-on project: Operation Great Escape. The goal is to see how AI actually helps you, with your own constraints, your expectations, and your decisions. Your mission: use generative AI to plan and organize a one-week getaway with friends. You will use it to explore a destination, structure your itinerary, anticipate the logistics, manage your budget, and put together a realistic plan.

Before the first real lesson, take two minutes to set up your project so every later chapter has something concrete to work with.
Instructions
Note the rough shape of your getaway: a possible destination, who is coming, and an approximate week. Nothing is final; you can change it all later.
Open one general-purpose AI tool you will keep using throughout the course (for example ChatGPT, Claude, Gemini, or Le Chat), and check you can start a conversation.
That is it. You now have a real context to apply the course to, starting in the very next chapter.
Ready to start? Next, we build an essential foundation: a clear view of what AI can really do, and what it should never do in your place.
