However, on the bank end, the application provides text that needs to be translated, and some other website uses this translated text by users for its translation. As the app is free and the entire learning experience is gamified, hooked users learn a new language. Despite translation tools being there in the market, they are not capable of precisely translating the same.Īnd this led to the rise of the Duolingo business model. On a similar basis, Duolingo takes the help of a human for translating a document from one language to another.
Re-CAPTCHA is a major crowdsourcing information program where the system takes information from users to verify if they are human.
Duolingo was based on a similar concept to Re-CAPTCHA. Luis Von Ahn (who is known for his work in CAPTCHA and Re-CAPTCHA) and his student Severin Hacker were the founders of Duolingo.
