Khan Academy

Khan Academy is a non-profit educational platform founded by Sal Khan in 2008 with a mission statement so ambitious it is almost hard to believe: provide a free, world-class education for anyone, anywhere. Two decades later, it has largely delivered on that promise — offering comprehensive courses in mathematics, science, computing, history, economics, and test preparation, completely free with no ads, no subscriptions, and no premium tier. The app brings the full Khan Academy experience to mobile, including video lessons, interactive exercises, and the increasingly capable Khanmigo AI tutor. Khanmigo takes a Socratic approach to tutoring: rather than simply giving students the answer, it asks guiding questions that lead them to discover the solution themselves. This approach has strong evidence behind it — students who work through problems with guidance retain concepts significantly better than those who are simply told the answer.

Final take

Khan Academy is one of the most genuinely good things on the internet — free, rigorous, non-commercial, and constantly improving. The Khanmigo AI tutor has elevated it from a video library into an interactive learning tool that rivals expensive tutoring services. For students, parents, and self-learners working on core academic subjects, it should be the first app you install. Its only real limitation is breadth: creative, vocational, and advanced professional fields are underrepresented. For academic subjects, nothing else compares at any price.
