Configurer votre premier outil

You know the families and how to match them. Now let's actually set one up. We'll keep it simple with a browser tool — by the end you'll have sent your first prompt.

The easiest start is a chat assistant in your web browser: no setup, just a chat box. Look for a free tier, pick one, and stick with it for now.

Most tools ask you to sign up with an email so they can save your chats. Use a real email you can access in case you need to confirm it.

Once signed in, look for the text box, usually at the bottom of the screen. That's where you type your requests — everything starts there. Spot it before moving on.

Let's send a friendly first message to check everything works. Type the prompt below, press Enter, and read the reply. You just talked to your AI assistant! 🎉

Now try a tiny real task: ask for a small piece of code you can copy. Notice it returns code and an explanation. Small wins build confidence.

The real power is the follow-up. You don't need it perfect the first time — just ask for changes. The tool remembers the chat, so you keep improving the same result.

When you like the code, save it: copy it into a file on your computer, or just keep the chat open so your history stays. Copying is a perfectly fine start.

To see an HTML file work, save it with a .html name and double-click to open it in your browser. Not ready for files? Many tools let you preview right in the chat.

Start with these habits: be specific, read the reply (don't copy blindly), ask follow-ups instead of restarting, and save your wins. They make every tool work better.

You've got a working tool and a first creation! From here, keep practicing, try an agent for bigger apps, and explore an IDE assistant for real projects.

One last check to wrap up the course.

You did it! You chose a browser chat assistant, found the chat box, sent a first prompt, built a tiny page, and learned to refine with follow-ups. Now choose the right tool with confidence.
