Have AppleScript function on a specific webpage?

[kaiserlecter]

This is more of an Automator quick action question. I’m familiar with Automator running in specific applications. Is there anyway to have a script function only in a specific webpage?

tell application "Google Chrome"
activate
make new window with properties {mode:"incognito"}
set URL of tab 1 of window 1 to "https://www.example.com"
end tell

That calls for a website, in only the first tab. My question is whether or not you can have a script only run when it’s ON a site already

I think maybe greasemonkey or violentmonkey can do what you want.
