History

Quizlet was conceived by Sutherland while he was studying for his French class.[8][9] To aid in memorizing words, he began writing a program to help him study.[10] These first lines of code were deleted and then rewritten over a course of 420 days. In October 2005, Quizlet was released to the public.[11]

Until 2011, Quizlet shared staff and financial resources with the Collectors Weekly web site.[12] In 2015, Quizlet announced raising $12 million from Union Square Ventures, Costanoa Venture Capital, Altos Ventures and Owl Ventures to expand its digital study tools and grow internationally.[6]

In 2011, Quizlet added the ability to listen to content using text-to-speech.[13] In August 2012, Quizlet released an app for the iPhone and iPad and shortly afterward released an app for Android devices.[12]

On April 29, 2015, Quizlet enabled HTTPS on their site.[14].

On August 10, 2016, Quizlet introduced a revamp to their website with a new design interface, along with a new logo and homepage. Their mobile apps for iOS and Android also received a design interface update.[15]

On August 23, 2017, Quizlet introduced a new diagramming feature[16] to help learners with subjects heavy on visuals like geography, vocabulary, anatomy, and architecture.

On February 6, 2018, Quizlet announced that it had raised an additional $20 million in Series B funding,[17] led by Icon Ventures.

On October 31, 2018, Quizlet announced the opening of their second office, which was located in Denver.[18]

On February 11, 2020, Quizlet introduced Night Mode to all of its users. Before this, Night Mode was only available for users with paid subscriptions.[19][20]

Study modes and games

As a memorization tool, Quizlet lets registered users create sets of terms and definition customized for their own needs.[21] These sets of terms can then be studied under several study modes.[22][23]

Flash Cards
This mode is similar to paper flash cards. Users are shown a "card" for each term, which they can flip over by clicking or using the arrow keys or space bar.[24] The user has the option for the face of the card to be an image, a word, or both.
Gravity
In this study mode, definitions scroll vertically down the screen in the shape of asteroids. The user must type the term that goes with the definition before it reaches the bottom of the screen. It is one of the 'Play' study modes.[25] Gravity was adapted from a previous game, Space Race. The user can pick the level of difficulty and game type.
Write
In this study mode, users are shown a term or definition and must type the term or definition that goes with what is shown. After entering their answer, users see if their answer was correct or not, and can choose to override the automatic grading and count their answer as right if needed. This mode was previously called "Learn."
Speller
In this mode, the term is read out loud and users must type in the term with the correct spelling. If the user gets every answer correct, they are rewarded with a video of a monster truck doing a jump, wheelie, and a flip. [24]
Match
In this study mode, users are presented with a grid of scattered terms. Users drag terms on top of their associated definitions to remove them from the grid and try to clear the grid in the fastest time possible. Micro-match is a related matching game geared towards mobile devices and devices with small screens. Users may access the Micromatch mode on non-mobile devices by manually editing the URL in Match mode to use "micromatch" instead of "match".[24] Match was previously attributed as "Scatter". Though the name of the study mode changed, the game itself did not.
Live
In this study mode, a Quizlet user (usually a teacher) breaks their class up into teams of however number of teams they want or play the game with students individually. The teacher chooses whether to start with a definition or term. Each team will have to choose the correct term/definition to win, with the team that has the most points winning. If the teacher decides to shuffle the teams, the groups are randomly put into new teams. This game works by choosing a set of flashcards and putting these flashcards into a format which works for the game. If a player or team chooses the incorrect term or definition,the score will reset.

Controversy

Quizlet, similar to other user generated content platforms, students on Quizlet often upload information that one can use to cheat within the classroom. [26] In a survey at a High School in Orlando, a student was quoted saying “If someone put $100 in front of you, would you take it?” asked the student who used Quizlet to cheat in high school."

API

Quizlet provides an API that allows others to access Quizlet data. Available functions include uploading and downloading flashcards, modifying users' flashcards, and finding definitions created by Quizlet users.[27]

gollark: ``` TrumpScript boycotts OS X and all Apple products until such time as Apple gives cellphone info to authorities regarding radical Islamic terrorist couple from Cal. The language is completely case insensitive. If the running computer is from China, TrumpScript will not compile. We don't want them stealing our American technological secrets. By constructing a wall (providing the --Wall flag), TrumpScript will refuse to run on machines with Mexican locales Warns you if you have any Communists masquerading as legitimate "SSL Certificates" from China on your system. Won't run in root mode because America doesn't need your help being great. Trump is all we need. Easy to type with small handsIf you find you can't get any TrumpScript to run on your computer (probably because we disallow the two most popular operating systems), you can specify the --shut_up flag to let the interpreter know you just want your code to run, damn it.```
gollark: ```Our language includes several convenient features, perfect for any aspiring Presidential candidate including: No floating point numbers, only integers. America never does anything halfway. All numbers must be strictly greater than 1 million. The small stuff is inconsequential to us. There are no import statements allowed. All code has to be home-grown and American made. Instead of True and False, we have the keywords fact and lie. Only the most popular English words, Trump's favorite words, and current politician names can be used as variable names. Error messages are mostly quotes directly taken from Trump himself. All programs must end with America is great. Our language will automatically correct Forbes' $4.5B to $10B. In its raw form, TrumpScript is not compatible with Windows, because Trump isn't the type of guy to believe in PC.```
