Your personal tutor for
math and coding

A world-class tutor for every home.
Built by top learning experts from MIT and Harvard.

Visual, interactive tutoring

Brilliant sees your work and notices when you’re off track. It asks guiding questions, patiently explains concepts with interactive diagrams, and sketches on your screen until you actually understand what to do and why.Share a photo of your schoolwork. Brilliant will review it, help you get unstuck, and work through any mistakes with you. Or, you can ask a question about a concept or topic and Brilliant will teach it to you. Each tutoring session builds foundational understanding, rather than just giving you the answers.Work through carefully sequenced concepts and targeted practice until you can solve problems independently. Brilliant helps you understand the structure behind math problems and computer programs, then works with you on reps and review until you’ve mastered the underlying skills.Brilliant uses diagnostics to pinpoint your current level, then starts you on a learning plan that adapts in real-time as you progress. Frequent assessments track what you’ve learned and what you’ve missed, and identify gaps in your understanding. Your plan accelerates when you’re ready, and slows down to help you rebuild foundations when needed.See what you’ve mastered, what still needs work, and what to tackle next. Your dashboard tracks your learning activity, performance on mastery assessments, and where you needed the most help.
