150M users. Free SAT prep (best available). 190 countries. "The future of education."
Khan Academy started as a math tutorial for a cousin in 2004 and now serves 150 million registered users across math, science, economics, history, and computing. Its SAT prep course, developed with the College Board, is considered the best free option available. Bill Gates called it "the future of education," with the Gates Foundation donating $16 million. The platform is used in 190 countries, translated into 50+ languages, and its AI tutor Khanmigo provides personalized Socratic tutoring. Everything is 100% free, with no financial aid required — a stark contrast to the 30% fee barrier of the Google UX Design Certificate (#3). Khan Academy's math curriculum alone covers 40% more topics than the average free course, making it the most comprehensive foundational resource for K-12 learners.
