Brilliant
Interactive STEM learning through guided problem-solving, with an adaptive AI tutor
About
Brilliant teaches math, science, computer science, and data analysis through hands-on interactive problems instead of lectures. Lessons are visual and bite-sized, built around solving rather than memorizing, aimed at learners roughly ages 13 and up including adults. Its AI tutor, Koji, is built into courses: it asks guiding questions, helps diagnose where a learner is stuck, and adjusts pacing without handing over answers. Guided learning paths organize topics from fundamentals to advanced material, and habit features like streaks and daily challenges keep practice consistent. Brilliant for Educators supports classroom assignments. The model is freemium: a limited free tier with a Premium subscription unlocking the full library.
