Your first generated app is a starting point, not the finish line. Using the chat right inside the designer, you can refine your app with simple follow-up messages until it is exactly right.
How iterating works
To improve your app, just describe the change you want in plain language. The AI applies it to your existing app, and you see the result in the live preview. Each message builds on what you already have, so your app evolves step by step.
For example, you might send requests like:
- "Add a dark theme."
- "Move the search bar to the top."
- "Make the buttons bigger and rounded."
- "Add a contact form to the home page."
Keep your requests focused
The single best habit for great results is to change one thing at a time. Focused requests are easier for the AI to get right, and they make it easy for you to see exactly what changed.
- One change per message. Instead of a long list, send several short requests in turn.
- Be specific. Say which screen or element you mean, for example "on the checkout page" or "the sign-up button."
- Describe the outcome. Explain what you want to see, not how it should be done.
Check the preview after each change
After every request, open the live preview and try the change. Confirming each step as you go keeps your app on track and helps you catch anything you want to adjust before moving on to the next idea.
Tips for smooth iteration
- Start with the big things like structure and main screens, then refine the details.
- Build up gradually. Small, steady steps add up to a polished app.
- Rephrase if needed. If a result is not what you expected, try describing it a different way with more detail.
- Keep momentum. A series of focused messages is faster than trying to get everything perfect in one go.
The iteration mindset
Think of building as a conversation. You guide, the AI responds, and together you shape the app over a series of small, clear steps. This back-and-forth is where good apps become great ones.
