History and Founding
Khan Academy was created by Sal Khan, who initially started recording educational videos to help tutor his cousins remotely. Recognizing the power and potential of this approach, he expanded the concept into a comprehensive educational platform.

Learning Platform and Features
Khan Academy's learning model is built on the principle of mastery-based progression. Students watch instructional videos and then complete practice exercises that provide immediate feedback. The system identifies misconceptions and areas where students need additional support. Adaptive learning recommendations suggest relevant content based on student performance and gaps. Teachers can create classes, assign specific videos and problems, monitor student progress in real-time, and identify which concepts students struggle with most. This data-driven approach allows teachers to provide targeted instruction and intervention.

Khan Academy is available in multiple languages, enabling its use globally.

The platform has been adopted in schools worldwide and is used by millions of independent learners pursuing self-directed education and skill development.
