About
PageDog is a local-first Mac app for monitoring the exact website change you care about.
Choose a page, select the visible area that matters, and describe one testable result—such as “alert me when this fare is below €80” or “tell me when an appointment slot opens.” PageDog checks on your Mac and uses hosted AI only when it needs to judge that goal.
Why it is different:
• Exact-goal monitoring instead of alerts for every visual change
• Persistent local browser session for many signed-in pages
• Flexible intervals, daily windows, specific check times, and weekdays-only schedules
• Local evidence and change history
• 20 completed AI checks free each month, no card required
PageDog supports Apple silicon and Intel Macs running macOS 12 or newer. Checks run while the app is open, the Mac is awake, and the network is available.
