A world-class tutor for every home. Built by top learning experts from MIT and Harvard.
Concepts that click
Every session is visual and interactive. Instead of just memorizing, you play with concepts until they click. And you work through problems step-by-step, building your intuition along the way.
Built to make you think
Like the best human tutors, Koji asks the right questions, provides visual guidance, and gets to the heart of where you’re getting stuck. It’s the difference between getting the answer and actually understanding it.
Adapts to exactly where you are
Koji tracks what you’ve mastered and where you’re stuck, then builds practice around the gaps. He speeds up when you’re ready, and slows down when you need it.
