Quizlet is a mobile and web-based study application that allows students to study information via learning tools and games. It is currently used by 1-in-2 high school students and 1-in-3 college students in the United States. Quizlet trains students via flashcards and various games and tests. As of April 30, 2018, Quizlet has over 200 million user-generated flashcard sets and more than 30 million active users. It now ranks among the top 50 websites in the U.S.
While there is not any risk of it disappearing soon, it contains a wealth of knowledge and info that AFAIK has no backup. It's always better to be prepared!
Quizlet ‘sets’ are incremental, with the earliest public set having the id ‘173’ and one of the more recent sets being above ‘300000000’. They do have an open API (see https://quizlet.com/api/2.0/docs) that returns a JSON copy of each set. An example API result can be seen here. Back of the napkin math shows that 300,000,000 public sets would take about 400 GB to store uncompressed.
Grabbing the Data
A grab for the API responses for all sets was ongoing. On September 23, 2018, Quizlet changed the API key signup process, requiring applicants to fill out a form for manual review. The grab has been put on hold since then.
Grabbed data is available below.
