Ahh I see. Then I would use something closer to what you just wrote there:

Works with Coursera, EdX, Udacity, The Great Courses, and Udemy courses.

I'd actually recommend changing the tagline on the site, as well, to be more clear: "Find the perfect study buddy for all your Coursera, EdX, and Udacity courses."

I like that. I think I may have to use that.
