> Bash already has autocomplete

What kind of autocomplete does bash have? Do I need to enable it? I've just tried bash 5.0.16. I don't see any. For example, I've typed `pw`, but `pwd` was not suggested to me.

(I know there's Tab-completion, this is not what I'm talking about. I'm looking for automatic completion. Similar to Google's search suggestions and CLUI demo.)
