Shipped PagePing: know when any page changes (email/Slack alerts)

The three use cases are close technically, but potentially very different buying behaviors.

With the early users you’re looking for, are you mainly trying to discover which use case gets the strongest initial interest, or which one actually creates repeated monitoring behavior after someone sets up their first page?

Clean execution, and "no CSS selectors needed" is the right wedge, that's the friction that kills every DIY version. But the make-or-break is your top use case: competitor pricing pages change constantly in trivial ways (A/B tests, copy tweaks, reordered FAQ). Alert on every diff and users drown and mute you within a week, same death as a stale spreadsheet, just louder.

So the real product isn't "detect changes," it's "detect changes that matter." The AI summary is your shot: if it says "price went up 10%" vs "reworded a heading" and only pings on the first, you're indispensable. If it just diffs everything, you're a commodity.

Do you let users filter by significance, or alert on any diff?

Quick context: I built this because I kept manually checking competitor pricing/terms pages every week.

Happy to set up 1–2 monitors for your real use case if anyone wants to try it.
