Duolingo Online Language Services

Duolingo is the world’s largest online language learning service. Our apps were selected by Apple as “iPhone App of the Year” and by “Google as Best of the Best for Android”, 2 years in a row. Unlike other online education platforms, Duolingo is a completely digital experience meaning it requires constant interaction and is native to computers / mobile platforms.

We’re funded by some of the world’s most prestigious venture capital firms, the investors behind Google, Twitter and Tumblr. Duolingo is a spinoff from Carnegie Mellon University’s School of Computer Science. Luis von Ahn, co-founder and CEO of Duolingo, is a MacArthur fellow, Carnegie Mellon University professor, and the inventor of CAPTCHA.

We believe that everyone should have access to free language education. Our guidelines are meant to build a mutual understanding of what being a part of this community is all about.

Duolingo’s adaptive experience has gamified elements to make language learning more fun and effective. 100 million students are learning a language with Duolingo. Did we mention that Duolingo is also 100% free!
