## Installation

### Prerequisites

- Python 3.8 or higher
- Node.js (optional, for any frontend tooling)
- Anthropic API key ([Get one here](https://console.anthropic.com/))

### Setup Steps

1. **Clone or download the project**

2. **Create a virtual environment (recommended)**
```bash
python -m venv venv

# On Windows
venv\Scripts\activate

# On macOS/Linux
source venv/bin/activate
```

3. **Install Python dependencies**
```bash
pip install -r requirements.txt
```

4. **Set up environment variables**
```bash
# Copy the example file
cp .env.example .env

# Edit .env and add your Anthropic API key
ANTHROPIC_API_KEY=your_actual_api_key_here
```

5. **Start the Flask server**
```bash
python app.py
```

6. **Open the application**
- Open `index.html` in your web browser, or
- Use a local server (e.g., `python -m http.server 8000`) and navigate to `http://localhost:8000`

## Usage

1. **Configure API Key**: Make sure your `.env` file contains a valid Anthropic API key.

2. **Start Backend**: Run `python app.py` to start the Flask server on port 5000.

3. **Open Frontend**: Open `index.html` in your browser or serve it through a local server.

4. **Start Chatting**: Type your message and press Enter or click the send button.

5. **Use Advanced Features**:
- **Voice Input**: Click the microphone icon to speak your message
- **Voice Output**: Click the speaker icon to have Claude's response read aloud
- **File Upload**: Click the paperclip icon to attach images or documents
- **Dark Mode**: Toggle dark theme from the header
- **Multiple Sessions**: Click the chat icon to manage multiple conversations
- **Export Chat**: Download your conversation history as PDF or TXT
- **Quick Templates**: Click the lightbulb icon for pre-built prompts
- **Search**: Use the search box to find specific messages

6. **Adjust Settings**: Click the settings icon to customize:
- Model selection (Claude 3.5 Sonnet, Opus, Sonnet, or Haiku)
- Max tokens (1-4096)
- Temperature (0-1)
- Stream response option
- Auto voice output
- Voice language selection
- Export/Import settings

## API Endpoints

### `GET /api/health`
Health check endpoint to verify API status.

**Response:**
```json
{
"status": "healthy",
"anthropic_configured": true
}
```

### `POST /api/chat`
Main chat endpoint for conversing with Claude.

**Request Body:**
```json
{
"message": "Hello, Claude!",
"model": "claude-3-5-sonnet-20241022",
"max_tokens": 1024,
"temperature": 0.7,
"conversation_history": [],
"stream": false
}
```

**Response:**
```json
{
"response": "Hello! How can I help you today?",
"model": "claude-3-5-sonnet-20241022",
"usage": {
"input_tokens": 10,
"output_tokens": 8
}
}
```

### `GET /api/models`
Get list of available Claude models.

## Configuration

### Environment Variables

- `ANTHROPIC_API_KEY` - Your Anthropic API key (required)
- `FLASK_ENV` - Flask environment (development/production)
- `PORT` - Server port (default: 5000)

### Frontend Configuration

Edit `script.js` to change the API base URL:
```javascript
const API_BASE_URL = 'http://localhost:5000/api';
```

## Available Models

- **Claude 3.5 Sonnet** - Latest and most capable model (recommended)
- **Claude 3 Opus** - Most powerful for complex tasks
- **Claude 3 Sonnet** - Balanced performance and speed
- **Claude 3 Haiku** - Fastest and most cost-effective

## Features in Detail

### Long Context Support
Claude can handle conversations with up to 200K tokens of context, making it perfect for extended discussions and document analysis.

### Advanced Reasoning
Claude excels at complex reasoning tasks, coding, mathematics, and multi-step problem solving.

### Safe AI Interactions
Anthropic's safety measures ensure responsible AI usage with built-in content filtering and safety protocols.

## Troubleshooting

### API Key Issues
- Ensure your `.env` file contains a valid `ANTHROPIC_API_KEY`
- Check that the API key is correctly formatted (starts with `sk-ant-`)
- Verify your API key has sufficient credits

### CORS Issues
- Make sure Flask-CORS is installed: `pip install flask-cors`
- Check that the frontend and backend URLs are correct

### Connection Errors
- Verify the Flask server is running on port 5000
- Check firewall settings
- Ensure no other application is using port 5000

## Security Notes

- Never commit your `.env` file to version control
- Keep your API key secure and private
- Use environment variables for sensitive data
- Consider implementing rate limiting for production use
