The organization produces short lessons in the form of videos. Its website also includes supplementary practice exercises and materials for educators. All resources are available for free to users of the website and application.
The organization started in 2006 when Salman "Sal" Khan tutored one of his cousins in mathematics on the Internet using a service called Yahoo! Doodle Images. After a while, Khan's other cousins began to use his tutoring service. Due to the demand, Khan decided to make his videos watchable on the Internet, so he published his content on YouTube. Later, he used a drawing application called SmoothDraw, and now uses a Wacom tablet to draw using ArtRage. The video tutorials were recorded on his computer.
Positive responses prompted Khan to quit his job in 2009, to focus full-time on creating educational tutorials (then released under the name Khan Academy). Khan Lab School, a school founded by Sal Khan and associated with Khan Academy, opened on September 15, 2014, in Mountain View, California. In June 2017, Khan Academy officially launched the Financial Literacy Video Series for college graduates, job seekers and young professionals.
Khan Academy is a nonprofit organization, mostly funded by donations coming from philanthropic organizations. In 2010, Google donated $2 million for creating new courses and translating content into other languages, as part of their Project 10100 program. In 2013, Carlos Slim from the Luis Alcazar Foundation in Mexico, made a donation for creating Spanish versions of videos. In 2015, AT&T contributed $2.25 million to Khan Academy for mobile versions of the content accessible through apps. The Bill & Melinda Gates Foundation has donated $1.5 million to Khan Academy. On January 11, 2021, Elon Musk donated $5 million through his Musk foundation.
Khan Academy's website aims to provide a free personalized learning experience, mainly built on the videos which are hosted on YouTube. The website is meant to be used as a supplement to its videos, because it includes other features such as progress tracking, practice exercises, and teaching tools. The material can also be accessed through mobile applications.
The videos display a recording of drawings on an electronic blackboard, which are similar to the style of a teacher giving a lecture. The narrator describes each drawing and how they relate to the material being taught. Furthermore, throughout the lessons, users can earn badges and energy points, which can be displayed on their profiles.
Non-profit groups have distributed offline versions of the videos to rural areas in Asia, Latin America, and Africa. Videos range from all subjects covered in school and for all grades from kindergarten up through high school. The Khan Academy website also hosts content from educational YouTube channels and organizations such as Crash Course and the Museum of Modern Art.
It also provides online courses for preparing for standardized tests, including the SAT, AP Chemistry, Praxis Core and MCAT and released LSAT preparation lessons in 2018. They also have a collaboration with independent chemists, which are mentioned in their, "Meet the chemistry professional". Khan Academy has also supported Code.org’s Hour of Code, providing coding lessons on its website.
Khan Academy videos have been translated into several languages, with close to 20,000 subtitle translations available. These translations are mainly volunteer-driven with help from international partnerships. The Khan Academy platform is fully available in English (en), Bangla (bn), Bulgarian (bg), Chinese (zh), French (fr), German (de), Georgian (ka), Norwegian (nb), Polish (pl) Portuguese (pt), Spanish (es), Serbian (sr), Turkish (tr) and Uzbek (uz), and partially available in 28 other languages.
