### 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
