About Brilliant
Overview
Brilliant is an interactive learning platform for math, computer science, science, and data analysis, built for learners from fifth grade through college. Its personal tutor, Koji, works problems with each learner on a shared interactive canvas instead of handing over answers.
Brilliant builds its curriculum with award-winning teachers, subject-matter experts, and learning designers from institutions such as MIT and Harvard. The company reports more than 10 million learners, holds accreditation from ACS WASC, and carries kidSAFE certification for children's online privacy and safety.
Key Benefits
- Koji asks guiding questions, sketches on the screen, and offers hints so learners arrive at answers themselves.
- The tutor tracks which concepts a learner has mastered and which they missed, then rebuilds the learning plan around those gaps.
- Visual dashboards and regular notifications report completed lessons, mastery assessment results, strengths, and topics that need more practice.
- A shared coding environment lets learners write and run code, debug code they did not write, and reason about correctness, data, and cost.
- Tutoring works around the learner's schedule, whether that means Sunday night before a test or twenty quiet minutes before dinner.
- Individual classrooms use Brilliant at no cost, and districts can request pricing for wider deployment.
How It Works
A learner, parent, or teacher picks a track such as math or coding and starts solving problems with Koji on a shared canvas. Koji watches the work, identifies where the learner gets stuck, and intervenes with a guiding question, a sketch, or a hint rather than the solution. Regular mastery assessments confirm understanding, and any missed concept triggers targeted practice before the plan moves forward.
Use Cases
- Middle and high school students shore up shaky fundamentals such as slope, quadratics, or trigonometry before a class test.
- Parents follow lesson completion and mastery results through regular progress notifications.
- Teachers run interactive math and coding lessons in class or as homework, free for an individual classroom.
- Homeschool families build a math and computer science curriculum around adaptive practice and mastery assessments.
- College students and adult learners pick up Python and CS foundations, from variables and functions to algorithmic thinking.
- School districts license the program across classrooms through district pricing on request.
Why Choose This Product
Brilliant sets Koji apart from AI chatbots and homework help tools by withholding answers and building independence instead. The math curriculum runs from fractions, percents, and linear equations through derivatives, matrices, and calculus, and it adds computer science, science, and data analysis tracks. Accreditation from ACS WASC, kidSAFE membership, and use in thousands of schools give parents and teachers documented reasons to trust the program.

Key Features
Koji AI Tutor
Koji is a personal tutor that asks guiding questions, sketches on the learner's screen, gives hints, and never simply hands over the answer.
Shared Interactive Canvas
Learners work problems alongside Koji on a shared interactive canvas that shows the tutor exactly where they get stuck.
Adaptive Learning Plans
The tutor tracks mastered and missed concepts, builds a plan around the gaps, and speeds up or slows down as the learner progresses.
Mastery Assessments
Regular assessments check each concept, and a shortfall generates targeted practice to get the learner back on track.
Progress Dashboards
Visual dashboards and recurring notifications summarize completed lessons, assessment performance, strengths, and areas needing practice.
Interactive Coding Environment
A shared coding environment lets learners write and run their own code, read and debug outside code, and inspect program structure.
40+ Interactive Courses
Premium opens unlimited access to more than 40 courses spanning math, computer science, science, and data analysis.
Real-World Applications
Lessons apply concepts to familiar situations such as building Instagram-style image filters or implementing website security measures.
Classroom Tools
Teachers fit the program into class or assign it as homework, and individual classrooms use it free with district pricing available on request.
