Page only for Username

I am trying to make different pages only viewable per one user.

For Example: I make a page called “Alex” and that page can only be seen by a username “Alex” if he’s logged into wordpress. Also the url would be .com/people/alex

I want to do this but for many pages easily.

I tried so many “members only” plugins but none do the trick. I even tried modifying the template, but no luck :/
