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 something real changes. Ads and clocks don't count.

How to use it — 3 easy steps
It compares every reload
Each fresh load gets compared with the one before. Noise like clocks and ads is ignored automatically.
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 knowing what NOT to count. Pages are full of stuff that changes every single load: clocks, ads, "14 people are watching this" counters. If those counted, you'd get pinged every time. Smart detection learns to ignore that noise and only fires on real changes — a new listing appearing, a status sentence rewritten, a page flipping from "coming soon" to "BUY NOW". Want it even sharper? Draw a Watch Zone and it only compares inside your box.

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。
How does it ignore ads and clocks?
Things that change on every single reload — the signature of ads, clocks and counters — get filtered out as noise. What's left is the real content. A Watch Zone narrows it even more, to exactly the box you drew.
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.
