Nope, is completely the same base. Scroll the homepage, and you'll see an example of Livecode (updated HyperTalk).

You can open your HyperCard stacks, or MetaCard stacks, or Runtime/Livecode Stacks in their IDE, code, edit, etc, similar to what you would have back in Hypercard days, but with modern features, updates, and additions.

It's backwards compatible with HyperTalk, its current language is an updated HyperTalk (i.e. an updated MetaTalk), that incorporates all that was, but adds new features for today.

Your Livecode apps can be deployed and run as cross-platform desktop applications (Mac, Win, *nix) , mobile applications, and as far as I remember, web applications with HTML5 deployment (so they say).

Not affiliated with them in any way, just sharing my understanding and memories.
