Brilliant Details

Brilliant is an interactive learning platform that pairs learners with an AI tutor named Koji for math, science, and computer science. Lessons are visual and hands-on, guiding students step-by-step through arithmetic, algebra, calculus, probability, Python, and related subjects from grade 5 through college level. Koji identifies what a learner has mastered and where they are stuck, then builds adaptive practice around those gaps while asking guiding questions to build intuition. The platform is built by award-winning teachers and learning designers from top institutions such as MIT and Harvard, and covers more than 30 courses. Gamified elements like streaks, levels, and daily goals motivate continued practice. Brilliant is available on the web, iOS, and Android, and reports over 100,000 five-star app store reviews and 10 million learners worldwide.
