About this extension

Super simple to use.

Automatically refreshes a tab at specified intervals and can notify you when specific text is found or not found - with an optional sound notification. Adapts to light and dark modes. Perfect for monitoring changes on web pages in real-time.

Customizable refresh intervals: Down to the second, minute or hour.

Text change detection: The reason this was developed. Can check for specific text on the refreshed page and alert you when it appears or disappears. Waiting for a game launch? Set it to notify you when "Coming soon" disappears, so you can be among the first to log in and snag that free year's subscription.

Sound alerts: Activate sound notifications for when the specified text changes, so even if you're multitasking, you'll never miss an important update.

Zero ads or data collection or anything like that: Just a simple add-on that does the job.

User-friendly interface: Sleek and intuitive interface makes it a doddle to use: clearly labelled input fields and checkboxes - and a big Start/Stop button. Test the optional audio alert before you use it.

Adapts to dark or light mode: Respects your system/browser settings - see screenshots.

I hope you find it useful. Enjoy. You're welcome!
