Duolingo is a freemium language-learning platform that includes a language-learning website and app, as well as a digital language proficiency assessment exam. As of August 2018, the language-learning website and app offer 81 different language courses across 37 languages. The app has about 300 million registered users across the world.

Duolingo has a freemium business model and it uses advertising in both its Android and iPhone apps. Duolingo courses include periodic advertisements which users can remove by paying a subscription fee. To earn money, Duolingo originally employed a crowd sourced business model, where the content came from organizations (such as CNN and BuzzFeed) that paid Duolingo to translate it.
