Brilliant review
A focused, interactive choice for math and science practice, with AI guidance and mobile sync.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Brilliant is an interactive learning platform for students, adults, homeschool families, educators, and lifelong learners. Its focus is math and coding, with additional content covering computer science, data science, science, technology, and AI. Learners work through visual explanations, interactive models, problem-solving exercises, personalized practice, and Guided Learning Paths. Koji, its AI tutor, adds step-by-step guidance, while streaks, XP, Weekly Leagues, and leaderboards provide progress and practice incentives.
The freemium structure makes Brilliant accessible before upgrading. The Free plan includes two lessons or practice sets per day, sequential course progression, a limited Koji preview, and occasional ads. Premium Monthly costs $30 per month and adds unlimited lessons and practice, full Koji access, the ability to jump to any lesson, and an ad-free experience. Premium Annual costs $240 per year with the same Premium features; the published annual-billing entry price is $20 per user per month. Premium is the clearer fit for learners who want unrestricted course access, flexible navigation, and continued practice.
Brilliant works across the web, iOS, and Android, with progress synchronization across devices. Its platform fit is strongest for learners who prefer guided, interactive STEM practice over lecture-heavy courses. The focused catalog can be an advantage for building math, coding, and science skills, but it is less suited to people seeking broad subject coverage, formal certificates, degree programs, or offline learning. Choose Brilliant for structured practice, visual explanations, and AI-supported problem solving; choose another MOOC platform if credential-focused learning or a wider academic catalog matters more.
