What We Do
Duolingo is a language-learning education platform that offers 98 total courses across nearly 40 distinct languages.
Duolingo is the world’s most popular way to learn a language. Our mission is to develop the best education in the world and make it universally available. Some of our products include:
1. Duolingo: The free, fun, and effective way to learn a language!
2. DET (Duolingo English Test): A modern language proficiency tool designed for today's international students and institutions. It offers an English proficiency score, video interview, and writing sample in an accessible, efficient, and secure testing experience.
3. Duolingo Math: An app that can make math be fun. For everyone. Students can focus on elementary math, which covers classroom topics, or adults can focus on brain training, which strengthens mental math skills and covers more advanced topics.
4. Duolingo ABC: An educational learning app that offers immersive lessons to teach preschool to second grade kids reading fundamentals.
Founded in 2011 by Luis von Ahn and Severin Hacker, Duolingo is the most downloaded education app in the history of the App Store and in 2019 became the top-grossing education app worldwide. The app has been awarded Apple's iPhone App of the Year and Android's Best of the Best.
