About
Khan Academy is a nonprofit educational platform that provides free, high-quality learning resources covering a vast range of subjects including mathematics, science, computing, history, economics, and test preparation (SAT, LSAT, GMAT). Founded by Sal Khan, the platform is used by over 150 million learners globally and partners with institutions like NASA, the College Board, and IITJEE. The platform features video lessons, interactive exercises, and personalized learning dashboards that adapt to each student's pace and progress. Teachers can assign content, track student performance, and identify knowledge gaps through robust classroom tools. Parents can monitor their children's learning journey in real time. Khan Academy also offers Khanmigo, an AI-powered tutoring assistant that guides students through problems using the Socratic method rather than simply giving answers — encouraging deeper understanding. Khanmigo also assists teachers with lesson planning and content creation. With structured courses aligned to Common Core and other curricula, Khan Academy is ideal for K–12 students seeking extra practice, adult learners upskilling or reskilling, college students preparing for standardized tests, and educators looking for supplemental classroom resources. The platform is entirely free for learners, supported by philanthropy and donations.
