🧩 Chrome extension — build UTMs right from your open tab
Install the browser extension and build a UTM link right on the product page you're viewing. The current tab URL is auto-filled, and non-ASCII (Korean) URLs are automatically cleaned into tidy ASCII links.
It recognizes major Korean commerce platforms — Cafe24, Godomall, MakeShop, Youngcart, Imweb, Sixshop, Naver SmartStore — and rewrites them to their original ASCII form. Works on Chrome, Edge, and Firefox, in Korean and English. The basics are free; web account sync, groups, and unlimited saves are Pro (7-day free trial).
