No indexing needed — for every message, the AI is shown the title, subject and description of every course below, and decides whether one is clearly relevant. If so, that lesson's page is fetched live and its full text is used to answer the question. Otherwise it answers from the course/tool list alone.

💡 Good descriptions matter — the more specific each course's description, the better the AI can tell when it's relevant. Edit descriptions in the Courses & Videos tab.
