Multi-document chat over an entire course
IntelligenZ chat draws from every document in a course at once — a midterm question can pull from week 3 lecture slides, the textbook PDF, and a YouTube review video in the same answer, with citations.
Why it matters: Real exams cross sources. Cross-document retrieval is what turns chat from "summarize this video" into "explain how the kinetics chapter connects to the lab we did in week 5."
