Demander à l’IA d’élaborer un plan

You've described your idea and broken it into steps. Now you can ask the AI to turn it all into a clear plan before any building starts.

A plan is a roadmap. It lists what will be built, in what order, so you both agree before work begins.

This lesson shows you how to ask for a good one.

Planning first saves time. You catch mistakes on paper instead of in the app.

It also helps the AI stay on track. With a plan, it knows where it's going instead of guessing step by step.

You don't need fancy wording. Just paste your idea and your steps, then ask for a plan.

Tell the AI the kind of plan you want: short, numbered, and easy to read.

A good plan is usually a numbered list, from the first thing to build to the last. Order matters — some steps need others to be done first.

Ask the AI to put the steps in the right order for you.

A plan is clearer when each step has a short reason. "Build the button first because the whole app depends on it."

Reasons help you understand the plan and spot anything that seems off.

AI assistants sometimes suggest big, fancy plans. Remind it to match your level and goal.

Say you're a beginner and want the smallest plan that gets a working app.

A good plan also points out the parts that aren't clear yet. Ask the AI to flag anything it's unsure about, or anything it needs you to decide.

This turns hidden surprises into simple questions you can answer.

You can ask the plan to name what tools or building blocks it will use — but in simple terms.

You don't have to understand every name. Seeing them just helps you ask questions if something seems too complicated.

When the plan comes back, read it slowly. Ask yourself:

• Does each step make sense to me?
• Is anything missing that I care about?
• Is anything more complicated than I wanted?

If something feels wrong, that's normal — you'll fix it next lesson.

The first plan is just a starting point. You're allowed to change it, cut things, or add things.

Don't feel you must accept it as-is. The best plans come from a back-and-forth between you and the AI.

Once you like the plan, keep it where you can see it. You'll use it as your guide while building.

You can even ask the AI to keep the plan in a simple file or note so you can check off steps as you go.

Let's check what you learned about asking for a plan.

You learned how to ask the AI for a clear plan:

• Ask in plain words for a short, numbered list.
• Ask for the order and a short reason per step.
• Tell it to keep things simple for a beginner.
• Have it flag unknowns and decisions for you.

Next, you'll learn to refine the plan together until it's just right.
