What does Duolingo do? Duolingo Inc was founded in 2011 by Luis von Ahn and Severin Hacker. The company's motto is "Freedom to learn passionately". The founders' idea was to create a free and accessible platform for language learners worldwide. Duolingo's business model is based on two pillars: advertising banners and premium subscriptions. Advertising targets learners on the platform, while premium subscriptions allow users to learn without ads and provide access to additional features and content. The platform includes various languages such as English, Spanish, French, German, Portuguese, Italian, and Japanese. It also offers languages like Irish, Welsh, and even Klingon. In addition to the main language learning program, Duolingo has also developed products for businesses, including a tool to improve employees' language proficiency. Duolingo's core program consists of the mobile application and website. Both are free and have millions of users worldwide. The application and website are based on a model that aims to make learning enjoyable for learners. By adapting to individual language levels and incorporating gamification elements like leveling up or rewards, Duolingo motivates its users. There is also a premium version that offers additional features and content such as quizzes, tests, or speaking exercises. Additionally, a mobile version with offline access is available. Duolingo is also involved in creating book series for language learners. These books are developed by experienced teachers and authors, providing a supplement to Duolingo's online offerings. Another important aspect of Duolingo is its collaboration with companies and governments.
