Lumen

Self-hosted AI platform that builds a private course from a learning goal and tutors you with cited answers.

Webfree

Lumen is a self-hosted, open-source e-learning platform where a learner types a one-sentence goal and an AI orchestrator builds a private course around it. A retrieval-based tutor then answers questions using citations from that course's own material, and finished courses can be shared or remixed through a moderated catalog. It is aimed at independent learners willing to bring their own AI provider key and self-host the platform.
