What I meant was tools like the one you can see on some websites, where the visitors can use it freely, for example a page where the user can paste text and that tools output the word's count, or anything else that a visitor can use (I've seen other websites offering tools for resolving equations, removing background and other complementary stuff related to that website topic).
