แบ่งแนวคิดออกเป็นขั้นตอน

A whole app can feel huge. If you ask the AI to "build everything" in one go, the result is often messy or confusing.

The trick is to break your idea into small steps. Small steps are easier to describe, easier to build, and easier to fix.

This lesson shows you how.

One easy way to find steps is to tell the story of using your app: first this happens, then that, next something else.

Each part of that story can become a step you build.

Every app has one core action — the main thing users do. For a water app, it's "add a glass." For a notes app, it's "write a note."

Build the core action first. Everything else is added around it later.

Write your idea as a short list of steps. Don't worry about order being perfect — you can fix it later.

You can even ask the AI to turn your idea into a list for you.

A good step is small and focused. If a step has the word "and" several times, it's probably too big — split it.

• Too big: "Add a button and save data and show charts."
• Better: "Step 1: add a button. Step 2: save the count. Step 3: show charts."

Put the simplest, most important steps first. Save the "nice extras" for the end.

This way you always have something working, and you add to it bit by bit.

Ask the AI to do one step, then try it. If it works, move on. If not, fix it before adding more.

This keeps problems small and easy to find.

Not every idea needs to be built right away. Mark each step as must have or nice to have.

Must-haves make the app usable. Nice-to-haves can wait. This keeps you focused.

When you list steps, you often notice something you forgot. "Wait — what happens when the day ends?"

Finding these gaps early is a good thing. It's much easier to plan for them now than to fix them later.

If you can't explain a step in one or two sentences, it's probably still too big. Break it down more.

Small, clear steps are the secret to smooth vibe coding. The AI follows clear steps far better than a giant wish list.

Here's how a water-app idea looks once it's broken into steps:

• Show a count of glasses, starting at zero.
• Add a button that increases the count.
• Remember the count after closing the app.
• Reset the count each morning.
• (Nice-to-have) Show a weekly chart.

Now each line is small enough to build and test on its own.

Time to check your understanding of breaking ideas into steps.

You learned to turn a big idea into small steps:

• Tell the story: first, then, next.
• Build the core action first.
• One step should do one thing.
• Order from simple to fancy, and split must-haves from nice-to-haves.

Next, you'll ask the AI to turn these steps into a real plan.
