Meet Koji,
your
personal
tutor
A visual, interactive tutor, not a cheating machine
Unlike other AI chatbots and homework help tools, Koji never just gives you the answer. He ensures you actually understand math.
You learn with Koji on a shared interactive canvas. He asks guiding questions, sketches on your screen, gives hints, and provides visual help.
Like the best human tutors, he gets to the heart of where you’re getting stuck, and works with you until you can solve hard problems yourself.
Adapts to exactly where you are
Koji tracks what you’ve mastered and what you’ve missed, then builds your learning plan around the gaps.
He gets you caught up on any shaky fundamentals, and personalizes your practice and review sessions to optimize your learning.
He accelerates your learning plan when you’re ready, and slows down when you need it.
Real-time progress tracking & analysis
Visual dashboards make it easy to see what clicked, what’s still difficult, and what to do next.
Parents and learners also receive regular notifications with an overview of completed lessons, performance on mastery assessments, learning strengths, and areas that need more practice.
A visual, interactive coding instructor
Like the best human instructors, Koji works with you until you master coding concepts.
You learn with Koji in a shared interactive coding environment. He asks guiding questions, sketches on your screen, gives hints, and provides visual help.
Write and run code yourself to learn CS foundations, how to read and debug code you didn’t write, and understand the structure of programs.
Build the CS skills that actually matter
AI has changed coding forever.
Brilliant’s learning framework builds the foundational thinking skills that successful programmers need in the age of AI: designing programs, solving problems methodically, and reasoning about correctness, data, and cost.
Unlike AI tools that just hand you code, Brilliant ensures you can work with code confidently and evaluate it yourself.
Real-time progress tracking & analysis
Visual dashboards make it easy to see what clicked, what’s still difficult, and what to do next.
You’ll also receive regular notifications, with an overview of completed lessons, learning strengths, and areas that need more practice.

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
I didn’t get the slope unit in class, but it finally clicked after talking to Koji for a few minutes!
Eliza
7th grader
It’s been a win-win. My son’s grades are up and he doesn’t complain about studying with Brilliant.
Hana
Parent of
16 year old
I learned most of trigonometry in 12 days, I just got into a flow. I’m one of the best in my class now.
Tyler
10th grader
They enthusiastically use it outside of class. I had 8th graders say, ‘This makes me want to do more math!’

Loved by learners of all ages
If you want to vibe code things that work instead of crash (like all my previous attempts) I highly recommend this.
Caleb
Marketing manager
GREAT little app! A day ago I only knew there was this thing called Python. Now I’m doing it.
Amy
Grad student
Currently obsessed with the CS lessons. This really proves anyone can learn to code.
Eric
Recent graduate
Visual learning changed everything! This was such a better way to learn coding for me personally.
Christoph
College freshman
I am not a coder. But I just wrote a function and understood why it worked. So… maybe I am now.
