Von Ahn’s goal with Duolingo, and his research, is to make the web accessible to people everywhere, no matter what language they speak, read or understand. Duolingo is doing something very similar. The program would present users with two words, one that his algorithm was having trouble deciphering and one that was in place to verify that the user was a human.īy typing the verification word correctly, reCAPTCHA then had confidence that the user typed the other word correctly, and thus, it had been discovered. Von Ahn’s former company, reCAPTCHA, was a trailblazing effort in the world of Crowdsourcing. The second part of the Duolingo business model is Crowdsourcing. One thing that von Ahn wanted in this product was that it be available to people of all socio-economic classes. Other language learning tools, Rosetta Stone, for example, have historically been only available to those with the disposable income to fund their learning.
