Duolingo | Mimi Bebe

Duolingo transformed language learning with its free, gamified mobile app, making education accessible and engaging for millions worldwide. Launched in 2011 by Luis von Ahn and Severin Hacker, it uses bite-sized lessons, points, and leaderboards to motivate users. The platform offers over 100 courses in 40 languages, from Spanish and French to Klingon and High Valyrian. While praised for its accessibility and addictive nature, critics sometimes question the depth of conversational fluency achieved solely through its methods, pointing to the need for supplementary practice. Duolingo's business model relies on ads, a premium subscription (Super Duolingo), and its English proficiency test.
