Interactive STEM lessons that teach through guided problem solving.

Brilliant is an online learning platform for math, computer science, science, data analysis, and AI topics. It emphasizes visual, step-by-step problem solving, with an AI tutor named Koji that adjusts practice based on what a learner has mastered or is struggling with.

Why it stands out

  • Focuses on active problem solving rather than passive video lessons.
  • Covers a broad STEM span, from arithmetic and algebra to neural networks and quantum computing.
  • Adaptive tutor experience aims to change pace based on gaps and mastery.
  • Designed for both independent learners and parent/teacher-supported learning.
  • Uses motivation systems such as streaks and goals to encourage regular practice.

Good to know

  • Subject coverage is strongly STEM-focused, so it is not a general-purpose tutoring platform for humanities or languages.
  • The page positions Koji as an AI tutor, not a live human tutor or real-time class.
  • Pricing details are not shown in the extracted landing-page text and require checking the separate pricing page.
  • The stated audience starts around grade 5, so it may not fit younger elementary learners.
