Set up monitors
without leaving the page
Our Chrome extension lets you point, click, and start monitoring any element on any website. No URL copying. No switching tabs. No configuration files.
Everything you need, right in your browser
The extension brings the full power of ChangeNotifier to every page you visit.
One-click element picker
Browse any website, click the extension icon, and select exactly which element to monitor. The extension generates optimized selectors automatically — no CSS or XPath knowledge needed.
Quick monitor setup
Configure check frequency, notification channel, and conditions right from the extension sidebar. Your monitor starts immediately — no need to open the dashboard.
Automation recording
Need to navigate past cookie banners, login screens, or multi-step flows? Record your actions and the monitor replays them before every check.
From browsing to monitoring in 30 seconds
Install the extension
Add ChangeNotifier to Chrome from the Web Store. Sign in with your existing account or create a new one — takes about 10 seconds.
Browse to any page
Navigate to the web page you want to monitor. The extension works on any publicly accessible site — including JavaScript-heavy single-page apps.
Select what to watch
Click the extension icon and hover over page elements. They light up as you move your mouse. Click to select the specific section you want to track — a price, a paragraph, a table, or the whole page.
Configure and go
Set your check frequency, choose where to receive alerts, and optionally add keyword or AI conditions. Your monitor starts immediately and appears in your dashboard.
Why use the extension?
The fastest way to go from “I want to track this” to actually tracking it.
No URL copying
Skip the copy-paste workflow. See something interesting while browsing? Monitor it right there, right now. No need to switch to the dashboard or type in URLs.
Visual element selection
See exactly what you're selecting with visual highlighting. Elements glow as you hover over them. Click to confirm — no CSS knowledge required.
Instant setup
Go from browsing to monitoring in under 30 seconds. The extension handles selector generation, page configuration, and monitor creation automatically.
Syncs with your dashboard
All monitors created via the extension appear instantly in your ChangeNotifier dashboard. Manage, edit, and review change history from anywhere.
