We created Duolingo so that everyone could have a chance. Free language education – no hidden fees, no premium content, just free.

Quizlet is used by more than 30 million students and teachers each month, on our website, iOS and Android apps. We’re found in classrooms in rounds of Quizlet Live, as part of study sessions at home, and in the hands of learners studying for everything from spelling tests to college-level science classes to professional certifications. 

 A word cloud is a graphical representation of word frequency. Type or paste text into the box below and press the arrow button to view the word cloud generated. The appearance of a word cloud can be altered using the graphical buttons above the cloud. It is also easy to save and/or print the cloud by simply pressing a button.

We are the first language learning program that adapts to every user. Other programs put you on the same linear path as every other user. But there is no average user. You're unique. We dynamically select content based on your personal interests and proficiencies. We also let you learn from real music that overlaps with your vocabulary and we introduce you to new words by how often they are actually used in the real world.
