Meet Koji,
your
personal
tutor
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.
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.

I wasn’t getting the slope unit in class, but it finally clicked after 20 minutes talking to Koji!
Eliza
7th grader
I didn’t expect him to learn this fast. He explained how to write algorithms at dinner tonight.
Noah
Parent of
16 year old
I learned the basics of Trigonometry in 12 days, I just got into a flow. I’m best in my class now.
Tyler
10th grader
She’ll get stuck on a problem and then yell, ‘Never mind, Mom, I got it!’ How great is that?
Arianne
Parent of
10 year old
They enthusiastically do it outside of class. I had 8th graders say, ‘This makes me want to do more math!’
