Pythagora is a French-language video platform with the slogan “Apprenez, découvrez et révisez comme vous voulez” (Learn, discover and review as you want). You can create an account and test out the beta version for free right now, but the regular subscription will be 5,99€ per month. In addition to the videos, there are also multiple choice questions and some “fiches” of information. Since the videos tend to be study materials for the Bac and Brevet, they are mostly designed for native or advanced speakers in the French education system.
The videos are grouped into the “chaînes” of Bac Français, Maths Brevet, Histoire Bac, Education média, Philosophie, Economie, Histoire des arts, Géographie Brevet, Histoire Brevet, Géographie Bac as well as two channels for learning English. The Bac Français channel has several videos on literature, but also a series on Les fautes qui tuent which explains common mistakes.
