This is a real alert, made by our real checking system — not a mock-up. The pictures and the highlighted change below come from the same system that runs your monitors, pointed at a fictional product page in its before and after states.

Step 1
Two real pictures
We take a picture of the page on every check — the same way, every time.
Step 2
A careful comparison
We compare the two pictures and outline exactly which parts changed — ignoring meaningless flickers no human would notice.
Step 3
Proof, plus a plain answer
You get one plain-language alert saying what changed and why it matters — with the pictures attached, so you can check it yourself.
