The project came to limelight towards the ending or the year 2009 in Pittsburgh. It was a Carnegie Mellon University professor invention whose name is Luis Von Ahn. He was also the same person that created the reCAPTCHA app. The ideas for Duolingo came from two different places. One dream of Luis Von Ahn is creating a program that would serve two purposes in one, this he calls “twofer”. This Service was set to teach users a foreign language, translating them into simple phrases in documents.
Origin and brief History About Doulingo Creator Von Ahn
Von Ahn was born and raised in Guatemala and he realizes how expensive it was for people in his community to learn and communicate in English. Severing Hacker was born in Zug, Switzerland, and he is the co-founder of Duolingo. Von Ahn believes that “free education will actually transform the world”. Therefore he thought to supply the people with an outlet to do so.
The project was originally backed up by Luis Von Ahn’s MacArthur fellowship and National Science Foundation grant (NSFG). Then additional funding was later sponsored by Union Square Ventures and actor Ashton Kutcher’s firm, A-Grade Investments. Core services of the platform are made for free to the public. There was advertising of the service in both Android and iPhone apps.
In 2014, precisely in July, this platform established a language certification service, a Test Center, as a new business model. Furthermore, in June 2015, a Duolingo spokesman noticed that the company has been going off from the translation business. But instead, focus on language certification and other business opportunities.
Duolingo Language Courses

The platform have some services for you to learn words and practice vocabulary as well.

There is an examination grade for users when they complete all the lessons that fits to a skill. Users win a point for each correct answer and lose one for any wrong answer. In an earlier version of the Doulingo app test, users would start with four lives. Both on early lessons and three on later lessons.
There is a specific timer feature, whereby they time the user for some seconds to answer 20 questions and given 7 or more seconds for each correct answer. This particular feature is only available after the purchasing for 10 lingots (lingots is the currency the site uses). It makes use of a data-driven approach to plan a lesson. During this process, the system supervises the questions users have problems with and indicate the mistakes they make.
