macOS 27 Golden Gate includes a Safari Notify Me feature that can watch a page for changes such as a price drop, restock, or newly opened registration. The update also introduces Describe an Extension, a natural-language way to create a small Safari extension from an instruction.
These are interesting alternatives to building another custom scraper for every small task. A watched event-registration page or a product restock is a good first experiment. An extension that copies a page title and source URL into a standard research-note format is another.
The limit is reliability: pages with dynamic content, sign-in requirements, or anti-bot controls may not behave as expected. Test with a public page, verify the notification actually arrives, and inspect any generated extension before granting permissions.
What to do: In Safari on macOS 27, try Notify Me on a public ticket page and a small Describe an Extension experiment on a non-sensitive site.
