KEY FEATURES

🎯 No-Code Web Scraper Setup Open any website, click Start Scraping, and ScraperQ auto-discovers list items and pagination type. AI detects fields, suggests column names, assigns data types, and generates selectors. Ready to extract data in under 3 minutes — no CSS, no XPath, no coding required.

🛡️ Auto-Healing Selectors (CSRE — Chrome Selector Repair Engine) ScraperQ monitors 6 health signals per selector: match rate, element count, content pattern, positional stability, attribute integrity, and uniqueness. When a website changes, CSRE runs a 4-stage repair: stable attribute fallbacks → semantic re-matching → 24-hour staged observation → AI-powered reconstruction as a last resort. You approve before the next run. This makes ScraperQ the only self-maintaining web scraper chrome extension on the market.

🤖 AI-Powered Data Extraction An LLM pipeline analyzes page structure to produce stable selectors and human-readable field names. Columns are named "product_name" and "price" — not "div:nth-child(3) > a". AI is applied precisely where it adds value, keeping credit costs low.

⚡ API-Aware Extraction Many websites load their data through backend APIs. ScraperQ detects API calls during authorized browsing sessions and can use them directly — faster and more reliable than HTML parsing on API-driven sites. Auth tokens stay local and are never uploaded.

📊 Site Intelligence Analysis Before extraction starts, ScraperQ evaluates JavaScript rendering depth, frontend framework signals, and site compatibility. It auto-configures crawl speed and rendering settings per site. Handles React, Vue, and Angular SPAs out of the box.

♾️ Infinite Scroll & Pagination Works on pages that load content while scrolling and on traditionally paginated listings. Handles next-page buttons, load-more buttons, and infinite scroll automatically.

⏸️ Pause & Resume with Checkpoints Close Chrome mid-extraction. Come back tomorrow and resume from the exact checkpoint — not from the beginning. Essential for large website scraping jobs.

🔄 Reusable Templates with Health Monitoring Build a scraping template once and run it for months. ScraperQ tracks selector health over time so your website scraper templates keep working even when sites redesign.

🔧 Data Transformation & Presets Built-in format presets clean and restructure extracted data before export. Remove duplicates, reformat dates, split or merge columns — inside the extension, no extra tools needed.

📥 Export to CSV, JSON, Excel & Google Sheets Download as CSV, JSON, or Excel. Or stream live to Google Sheets — rows appear in your sheet in real time as the extraction runs. No waiting for the job to finish.
