How It Works

1. Content Script (content.js) runs on Netacad pages and detects quiz elements using Shadow DOM
2. Netacad uses Shadow DOM to encapsulate quiz content, so the script accesses the mcq-view element's shadow root
3. The script extracts question text and options from inside the shadow DOM
4. User clicks either the green button (simple model) or red button (advanced model)
5. Background Script (background.js) sends the question to the selected AI model via OpenRouter or legacy provider
6. The AI responds with only the correct option letter (A, B, C, or D)
7. The extension highlights the corresponding option with inline styles (since CSS doesn't penetrate Shadow DOM)

Privacy & Security

• API keys are stored locally in Chrome's sync storage
• No data is sent to any server except the AI provider you choose
• The extension only runs on netacad.com domains

Limitations

• AI suggestions may not always be correct - always verify answers
• Requires a valid API key (OpenRouter, Groq, or Gemini)
• Free options available (OpenRouter, Groq, and Gemini offer free tiers)
• API usage may incur costs for premium models
• Only works on multiple-choice questions
• For best results, use the appropriate button (simple vs advanced) based on question type

Troubleshooting

Extension buttons not appearing

• Make sure you're on a Netacad quiz page with multiple choice questions
• Refresh the page after installing the extension
• Check that both green and red buttons are visible

API errors

• Verify your API key is correct (OpenRouter or Legacy provider)
• Check that you have API credits/quota remaining
• Ensure you selected models that match your API key
• For OpenRouter models, make sure you entered the OpenRouter API key

No answer highlighted

• Check the browser console for errors (F12)
• Verify the question format is supported
• Try switching between simple and advanced models
• Ensure the correct model is configured for the button you clicked

Wrong model being used

• Check which button you clicked (green = simple, red = advanced)
• Verify model selections in the extension popup
• Make sure the appropriate API key is configured
