Interactive, problem-based lessons
Lessons are presented as interactive problems rather than passive video or reading-only content, so learners work through concepts step by step.
What Brilliant is
Brilliant is an interactive learning platform focused on math, programming, data analysis, science, and AI. It is built around guided problem solving, where learners work through visual, step-by-step exercises instead of only reading explanations or watching lectures.
The site positions Koji as a personal tutor that adapts to a learner’s progress, asks questions, and provides visual guidance when they get stuck. Brilliant also organizes its content into courses and learning paths for learners, parents, teachers, and homeschooling use, with Premium unlocking full access to the course library.
Across the site, Brilliant emphasizes practice, immediate feedback, and structured progression from grade-school math through college-level topics and beyond. It is available on the web and through mobile app downloads for iOS and Android.
