Duolingo

Duolingo is highly regarded by society as the place to learn languages^{[not anymore][ai translations][anime pollution][they've gone full ai mode now]}, alongside math and music. However, its popularity is dwindling down due to the rise of comprehensible input and Duo's infamous tactics to get learners back to a daily streak when broken.

Duolingo revolves around a multilingual owl named Duo who seems to know every language from French to Diné bizaad (Navajo) to even Klingon. The more multilingual the student, the better. For less multilingual and/or active students are subject to Duo's dank memes.
