This application leverages the power of the Google Gemini API to provide rich, dynamically generated content. When you click on the "Generate" buttons for sections like "Word in Context Story," "Quiz Question," or "Cross-Language Translation," the application makes a call to the Gemini API with a specific prompt based on the currently displayed word. The AI then processes this request and returns relevant text or structured data (like quiz questions or translation details), enhancing your learning experience beyond static dictionary entries.

To run this application with full AI functionality, you'll need a Google Gemini API key. Follow these steps:

1. Go to Google AI Studio: Visit https://aistudio.google.com/.

2. Sign In: Sign in with your Google account.

3. Create API Key:

   • In the left sidebar, click "Get API Key" or "Create API Key."

   • You might need to create a new project first if you haven't done so.

   • Copy the generated API key.

4. Integrate the Key: In the index.html file, find the line:

   const apiKey = "YOUR_GEMINI_API_KEY_HERE";

   Replace "YOUR_GEMINI_API_KEY_HERE" with the actual API key you obtained from Google AI Studio. Note: In a Canvas environment, the apiKey variable ("") is often automatically provided or handled by the environment, so direct modification might not be necessary if running within such a platform. However, for local development outside Canvas, you would replace it.

1. Clone the repository:

   git clone [https://github.com/your-username/vocabulary-checker-app.git](https://github.com/your-username/vocabulary-checker-app.git)

   (Replace your-username with your actual GitHub username if you fork it)

2. Navigate to the project directory:

   cd vocabulary-checker-app

3. Open index.html: Simply open the index.html file in your web browser. No local server is required.

4. Enter a word in the input field and click "Search Word".

5. Explore the detailed information and click "Generate" buttons for AI-powered content.

6. Use "Save Current Word" to store words and "Load Saved Words" to retrieve them.
