Meet Koji,
your
personal
tutor
Concepts that click
Every session is visual and interactive. You don’t just memorize concepts — you play with them hands-on, until they click. You work through problems step-by-step, building intuition as you go.
Built to make you think
Koji asks the right questions, provides visual guidance, and gets to the heart of where you’re getting stuck — the way the best human tutors do. 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.
Designed to keep
you learning
Brilliant is designed to feel like a challenge, not a chore. Streaks, levels, and daily goals motivate you to build on your progress and keep moving forward.
From grade 5 to college and beyond
Always on your
schedule
Say goodbye to trial-and-error hiring, driving across town, and fitting another thing into your schedule. Koji is there Sunday night before the test, Saturday morning for fun, and the quiet 20 minutes before dinner.

experts
