AI Virtual Try-On Application

This is a web application built with Next.js that allows users to virtually try on clothing items using AI. Users upload a photo of themselves and a photo of a clothing item, and the application leverages the Google Gemini API to generate an image simulating the user wearing the clothing.

Features

  • 👤 User Image Upload: Upload a photo of yourself.
  • 👕 Clothing Image Upload: Upload a photo of a clothing item.
  • 🖼️ Image Previews: See previews of the uploaded images.
  • ✨ AI-Powered Try-On: Uses the Google Gemini API (specifically a flash experimental model) to generate the virtual try-on image.
  • ✅ Result Display: Shows the generated image result.
  • ⏳ Loading State: Displays a loading indicator while the AI is processing.
  • 🔄 Reset Functionality: Easily clear all inputs and results.
  • 🎨 Simple UI: Clean interface built with Tailwind CSS.

  2. Install Dependencies:

  3. Set Up Environment Variables:

    • Create a new file named .env.local in the root of your project directory.
    • Add your Google Gemini API Key to this file: 
      # .env.local
