Yeah, but it's not like it's built in to a product like Crunchyroll. There are separate tracking apps available for non-anime media as well.
There's also several sites for anime. I personally use Anilist. It even implements the same kind of activity grid that GitHub has for commits. https://anilist.co/user/Mailia/
anime isn't a product but more of a category. you can also track shows you watch on netflix (or anywhere else) on platforms like trakt or even imdb. though i wouldn't be surprised if netflix at some point adds (or at least beta tests) a social profile like steam and notifications like "your friend is watching X" or "your friends are watching horror, see our great selection bla bla bla".
Netflix is missing out.
Anime has that. See myanimelist.net, where you can sign up and check off episodes as you see them.
