Overview
Brilliant is a subscription learning platform focused on interactive mathematics, computer science, science, and related technical subjects. Lessons use problems, visual models, coding exercises, immediate feedback, assessments, and learning paths instead of relying only on passive video instruction. Koji is Brilliant’s digital tutor. Official pages describe a tutor that can inspect the learner’s work, ask guiding questions, offer hints, explain concepts, review uploaded homework, and adapt practice to gaps. Brilliant also teaches AI topics and programming skills for working with AI. The product is delivered as a web and mobile service, not as an open-source application.
