XueDao
XueDao is Clairvoyant Lab's learning + credentialing platform — the meeting point for universities, corporations and professional institutes. Lao Shi launched first on XueDao's own learners: S243 indexes every PDF teachers upload; S240 (Tutor) replaced the old "ask the chatbot anything" widget with a Socratic, Bloom-tagged conversation that refuses to do the learner's assignment; S246 helps teachers grade essay submissions; S247 drafts quiz items for new courses with source citations to the corpus just indexed.
- Stack: Moodle (xuedao.io) + ClairVAS S240–S247 + the LTI 1.3 tool provider at xuedao.kyzenn.org.
- Result: teachers report ~30% less time spent re-explaining covered material — students hit S240 first and arrive at office hours with sharper questions.
- Why it works: the impartiality wall in S240 + the cite-from-corpus discipline in S241 make the AI behave like a TA, not a homework solver.
