Not limited to STEM — generate an interactive course on any subject.
Grounded in your own materials, with a tutor that cites them.
Rubric grading, a GPA, and a certificate — real assessment, not just practice.
Open-source, self-hostable, and a free plan to start.
Yes. Brilliant focuses on math, science, and CS; Learnidex generates interactive courses — with simulations, drag-and-drop, branching scenarios, and flashcards — for any subject you name.
Yes — checkpoint quizzes, flashcards, drag-and-drop, branching scenarios, data visualizations, and parameter-based simulations, alongside readings and a source-citing tutor.
No. On the hosted plans everything — course generation, grading, the tutor, and search — runs on our platform. Self-hosters can bring their own key (Anthropic, OpenAI, OpenRouter, or a local Ollama model).
There's a free plan (one AI-generated course a month). Student is $20/mo (10 courses) and Pro is $35/mo (25 courses). Enrolling in a marketplace course others built is always free.
