Khan Academy

Khan Academy is a nonprofit educational platform that gives learners free access to lessons, prACTice exercises, and instructional vIDEos across a broad range of subjects. Originally known for its math curriculum, it has expanded into science, history, economics, finance, and test preparation. Its newer AI-assisted tutoring features are designed to support learners as they work through problems rather than simply supply answers.

What it does

The platfORM organizes learning into courses with short instructional videos, written explanations, and interactive practice sets. Progress tracking helps learners move from one Skill to the next, and mastery-style exercises adapt to performance. An integrated AI assistant, often described as a tutor, aims to guide students through reasoning steps and explain concepts in plain language.

Key capabilities

• Structured courses spanning arithmetic through advanced math, plus physics, biology, history, and economics.
• Practice with feedback that highlights mistakes and offers hints and step-by-step explanations.
• AI-guided help intended to encouRAGe problem solving instead of handing over final answers, though behavior and availability may vary by course and region.
• Teacher and parent tools for assigning work and reviewing learner progress in classroom or home settings.
• Accessible formats including web and mobile app experiences, making study possible on many devices.

Who it is for

Khan Academy serves students from early grades through college, adult learners refreshing foundational skills, parents supporting children at home, and teachers looking for supplemental materials. It is especially useful for self-paced study and for learners who want extra explanation outside a classroom.

How to get started

Create a free account on the website or through the mobile APP, choose a subject or grade level, and begin with a placement or course overview. Learners can follow recommended lessons in sequence or jump directly to a topic. Teachers can set up a class, invite students, and track assignments. Since the platform changes over time, the exact feature set and AI tool availability may differ from what is described here.
