SkillDiscs turns any source — article, YouTube video, PDF or GitHub repo — into a Disc: a guided course for you, plus clean structured context for your AI. You don't just collect links, you build understanding: a self-assembling knowledge graph, a voice tutor that explains and quizzes you, and concept maps across documents. Via API and MCP, any Disc becomes a skill for your agents. No account needed for your first Disc.
