WebSense AIとは
AI-powered web change monitoring. Know WHAT changed and WHY it matters. Stop manually refreshing pages to check for updates. WebSense AI monitors any website for you and sends an alert the moment something changes — whether it's a price drop, a content update, a competitor's new product, or a job posting going live.
Unlike basic page diff tools, WebSense AI uses AI to understand changes. It filters out noise (timestamps, session tokens, counters) and tells you what actually changed and whether it matters.
HOW IT WORKS
1. Visit any web page and click the WebSense AI icon 2. Point and click to select the element you want to monitor 3. Set your check interval — done. You'll get notified when it changes.
WHAT YOU CAN MONITOR
- Product prices on any e-commerce site (Amazon, eBay, Shopify stores, etc.)
- Competitor websites — new products, pricing changes, content updates
- Job listings — get alerted when new positions are posted
- Stock availability — know the moment an out-of-stock item is back
- News and blog pages — track articles, press releases, policy updates
- Government and regulatory pages — stay on top of legal changes
- Any web page element with text content
