DuoLingo

Learn a language for free. Forever.


A few months ago Freia mentioned that she was learning Spanish using a website called DuoLingo. What I recollect from that conversation was that it was free. And she found it pretty good.


Recently I was listening to an Audible Original Series called "Genius Dialogues" The Genius Dialogues is the podcast with MacArthur 'Genius Grant' Winners. This podcast featured Luis von Ahn the creator of DuoLingo. He had also built ReCaptcha, which he sold to Google, and then moved on to build DuoLingo.

Here's a quick intro from their website.


What I found fascinating was how they manage to keep the application free and yet sustainable. And the idea is rather simple. The site gets its students as part of its learning to translate content from the language they are learning to their native language. And these translation services are paid for by clients, such as CNN who have their content written in English and have it then translated into other languages, such as Spanish. This funds the project and allows them to continue to offer language learning for Free.


Here's how they do it in their words.


To learn more, you can listen to Luis von Ahn at a TedX presentation.
