Change detection — spot the difference, automatically
Sometimes you don't know what the page will say — you just know it'll be different when the big moment comes. Smart change detection plays spot-the-difference with every reload and pings you when the visible text changes. Draw a Watch Zone and only your box counts.

How to use it — 3 easy steps
It compares every reload
Each fresh load gets compared with the one before. Hidden elements and embedded ad frames are skipped.
02
Real changes ring the bell
Something genuinely new or different? Your alert fires. Cosmetic churn? Silence.

01 — What it does
It works like the spot-the-difference game. RefreshPilot takes a picture of what matters on the page (not a real photo — a clever fingerprint of the content). On the next reload, it takes another one and compares: same? Stay quiet. Different? Something new happened — ping! You never have to guess the magic words in advance.
The "smart" part is what it leaves out. It reads the text you can actually see — hidden elements, scripts and embedded frames (where most display ads live) are skipped. But pages also carry text that changes on every load: clocks, "14 people are watching this" counters, rotating promos. Those do count, so for a busy page, draw a Watch Zone around just the part you care about. Then it only fires on real changes there — a new listing appearing, a status sentence rewritten, a page flipping from "coming soon" to "BUY NOW".

Good questions
关于工作原理、哪些免费、PRO 解锁什么的直接解答。还有遗漏？我们会在一个工作日内回复。
Will ads and clocks trigger it?
Ads inside embedded frames don't — frames, scripts and hidden elements are never read. Clocks, counters and rotating text in the page itself do count as changes. On a busy page, draw a Watch Zone around the part you care about, and only changes inside that box will alert you.
Keywords or change detection — which one do I want?
Know the exact words? Use keywords — sharper. Only know "it'll look different"? Use change detection. And you can combine them: a zone plus keywords for precision, a zone plus change detection to catch anything.
What if the page changes without reloading?
Covered — Live Detection watches the page between reloads too. Queues, liveblogs and scoreboards that update themselves are still caught.
