Where can I download AppleScript Studio?

I've heard about AppleScript Studio many times, but I cannot find any download links.

A tutorial said that I could launch Xcode and select AppleScript under Application when starting a new project, but there wasn't anything listed, which had anything to do with AppleScript.

How do I run AppleScript in Windows?

You can't. Applescript is unique to Mac OS.

What script does Apple use?

AppleScript is a scripting language created by Apple. It allows users to directly control scriptable Macintosh applications, as well as parts of macOS itself.

AppleScript Studio was the name used to describe creating an AppleScript application using Xcode, not a separate application. Apple no longer uses the name, and it is called a Cocoa-AppleScript application. enter image description here

AppleScript Studio is no longer included in Xcode as of Xcode 4. But there is AppleScriptObjC, a framework which lets you write Cocoa apps using AppleScript.
