Today, I’m showing you something mind-blowing. We are going to build our own AI app in less than 5 minutes using Google AI Studio and "Vibe Coding"—which basically means using natural language to program an app without writing a single line of code.
Step 1: Go to Google AI Studio
Head over to aistudio.google.com.
On the left-hand panel, click on Build.
Select Start building with Gemini.
Step 2: Enter the "Vibe Coding" Prompt
In the text field, you are going to tell Gemini exactly what to build.
Type this prompt: I need to create an app with Nano Banana that allows me to input a character image and a product image, and Nano Banana will generate an image of the character using that product while keeping the original size and aspect ratio of the image. The final complete image output should not show stretched or distorted. It should fit proportionally and be fully viewable without having to scroll. The final image output should also be downloadable.
Hit Run Prompt.
Step 3: Let AI Build the App
In less than 2 minutes, Google AI Studio will generate the working application for you in real-time.
Step 4: Swap the Outfit
Once the app is ready, drag and drop a photo of yourself (the character).
Then, drag and drop an image of a shirt or sweater you found online (e.g., from Pinterest or Nike). Tip: Images with white backgrounds or cropped to the torso work best.
Hit Generate.
And that’s it! The AI will instantly dress your character in the new outfit.
