Andrew Chen
Online Shopper
I saved $150 on a laptop by setting price alerts. When I visited the store and the price had dropped below my target, ContextAlert showed me the reminder right there on the page. Perfect timing!

Marta Rodriguez
Frequent Traveler
I needed a consular appointment that sold out in minutes. With ContextAlert, the alert appeared right when I opened the page and I booked in 30 seconds. No more refreshing a thousand times or anxiety.

Lisa Thompson

I never miss concert tickets anymore. When I browse the ticket site and sales have gone live, ContextAlert reminds me right there on the page. It's like having a smart assistant that knows exactly when to show up.
