🛠️ Development Setup

Prerequisites

• Node.js 18+ and npm
• Google Chrome browser

1. Backend Development (Optional - Uses Live API)

The extension connects to the live backend at https://clarityai-qrnk.onrender.com by default. For local development:

cd "e:\ClarityAI\backend"
npm install
npm run dev
# Backend runs at http://localhost:3000

2. Extension Development

cd "e:\ClarityAI\chrome-extension"
npm install
npm run build

3. Load Extension in Chrome

1. Open chrome://extensions/
2. Enable "Developer mode"
3. Click "Load unpacked"
4. Select the e:\ClarityAI\chrome-extension\dist\ folder

4. Test the Extension

1. Visit any webpage with content
2. Click the floating "Summarize" button or ClarityAI icon
3. View the summary in the slide-out panel

🌐 API Endpoints (Live)

Base URL: https://clarityai-qrnk.onrender.com

• GET /: Welcome message
• GET /health: Health check and server status
• POST /api/summarize: Generate AI-powered summary
  • Body: { content: string, title: string, url?: string }
  • Returns: { points: string[], timestamp: string, wordCount: number }
• POST /api/extract: Extract content from URL
  • Body: { url: string }
  • Returns: { title: string, content: string, excerpt: string, ... }

Example API Usage:

// Summarize text
const response = await fetch(
  "https://clarityai-qrnk.onrender.com/api/summarize",
  {
    method: "POST",
    headers: { "Content-Type": "application/json" },
    body: JSON.stringify({
      content: "Your article content here...",
      title: "Article Title",
    }),
  }
);
const summary = await response.json();

📊 How It Works

Content Detection

1. Semantic HTML: Looks for <article>, [role="main"], .content
2. Readability Algorithm: Scores elements based on content density
3. Noise Removal: Filters out ads, navigation, sidebars
4. Fallback: Uses full page content if other methods fail

Summarization

• Position scoring: Prioritizes opening sentences
• Length optimization: Prefers 10-30 word sentences
• Keyword matching: Boosts sentences with title keywords
• Content indicators: Recognizes important terms and numbers

🔒 Privacy & Security

• Local storage: Summaries stored locally in Chrome
• No tracking: No analytics or user data collection
• CORS enabled: Secure backend communication
• Minimal permissions: Only necessary Chrome permissions

🚀 Future Enhancements

• AI Integration (OpenAI, Claude)
• Custom summary lengths
• Multiple summary formats
• Highlight integration
• Sharing features

🐛 Troubleshooting

Extension not working?

1. ✅ Backend is live: Uses https://clarityai-qrnk.onrender.com (no local setup needed)
2. ✅ Check Chrome extensions: Go to chrome://extensions/ for errors
3. ✅ Reload extension: After code changes, reload from extensions page
4. ✅ Check permissions: Ensure extension has access to the current site

Content not extracting?

• ✅ Works best on articles: News sites, blogs, Medium posts
• ⚠️ JavaScript-heavy sites: May need page refresh for dynamic content
• ⚠️ Social media: Limited support for Twitter, Facebook, etc.
• ✅ Test on: CNN, BBC, Medium, Wikipedia for best results

API Issues?

• ✅ Check status: Visit https://clarityai-qrnk.onrender.com/health
• ⚠️ Free tier limits: Render free tier may have cold starts (first request slower)
• ✅ CORS enabled: Should work from any domain
