Duolingo is an American education-technology company best known for its green owl language-learning app that turns studying into short, game-like lessons.

Who or what “Duolingo” is

  • Duolingo, Inc. is a company that builds learning apps and online tests, not a single person.
  • It was founded in 2011 by Luis von Ahn and Severin Hacker and is headquartered in Pittsburgh, Pennsylvania.
  • The brand is often personified through its mascot, Duo the green owl, which is why people online sometimes talk about “Duolingo” like it’s a character.

What Duolingo does

  • The main product is the Duolingo app, which offers courses in over 40 languages, from big ones like English and Spanish to smaller or constructed languages like Welsh, Navajo, and Klingon.
  • The app uses gamification: streaks, points, rewards, and short daily lessons to keep people coming back.
  • Beyond languages, Duolingo now also has courses for music, math, and even chess, expanding into a broader learning platform.
  • The company also runs the Duolingo English Test, an online English proficiency exam accepted by thousands of institutions worldwide.

Why Duolingo is a trending topic

  • Duolingo is one of the world’s most downloaded education apps and has tens of millions of monthly active users, so its updates and design changes often spark big conversations on forums and social media.
  • Its marketing leans hard into humor and the “intense” personality of the owl (jokes about not missing your streak), which has become a common meme and fuels ongoing online discussion.
