Duolingo Language Lessons

Duolingo is a leading educational technology platform primarily known for its language-learning mobile application. Developed originally by Luis von Ahn and Severin Hacker at Carnegie Mellon University in Pittsburgh, Pennsylvania, the brand has grown into a global phenomenon.

As a digital product, it is developed and maintained in the United States, though its services are accessible worldwide. Duolingo Inc. is a publicly traded company on the NASDAQ exchange (DUOL). The platform uses gamification to encourage users to practice languages, and it has since expanded into mathematics and music education.
