Learnidex vs Khan Academy · Free education platform
Any subject, from your sources — not a fixed curriculum.
Khan Academy offers excellent, free, curated lessons across a set curriculum (largely K-12 and intro college). Learnidex generates a course on any subject you name, built from your own materials, with grading, a concept map, and a tutor grounded in your sources.

Not restricted to a fixed curriculum — generate a course on any goal, at any level.
Lessons and the tutor are grounded in your own uploaded sources, not a general catalog.
Rubric grading with letter grades, a GPA, and a shareable certificate.
Open-source and self-hostable, so you can run it your way.
Learnidex has a free plan (one AI-generated course a month) and free marketplace enrollment. Khan Academy is entirely free as a nonprofit; Learnidex adds paid plans for generating more courses and offers self-hosting.
Khanmigo tutors on Khan Academy's own content. Learnidex's tutor is grounded in the specific sources you provide for your course, with citations you can click back to.
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.
