How monitoring works
ZeroHedge and Tom's Guide both noted that Safari on iOS 27 goes beyond AI-powered tab management to add a passive web page surveillance feature. Users can enable monitoring on a page — a live-updated article, a product page, an events schedule — and Safari sends a notification when it detects substantial content changes. The feature integrates with Apple Intelligence to distinguish relevant updates from minor changes such as advertising or layout shifts.
Concrete use cases
The most immediate scenario is online shopping: monitoring a product price without having to periodically return to the page. But the feature also lends itself to following breaking news updates, ticket availability, changes to public documents, or institutional announcements. Third-party desktop browsers and some extensions have offered this for years; what is new is the native integration in the world's most widely used mobile browser.
The walled garden limit
A legitimate question concerns privacy: to monitor a page, Safari must periodically make requests to that server. Apple has not yet detailed how this is handled in terms of request frequency and data treatment, especially for pages requiring authentication. These are aspects that technical documentation and this week's WWDC sessions should address.
