Perfect for dense source material
Uploaded 200 pages of regulation and asked questions for two hours. Every answer pointed at the exact passage. The audio overview is a surprisingly good way to revise.

Our review of NotebookLM
NotebookLM is the antidote to hallucination anxiety: it only answers from sources you provide and cites them line by line. That makes it excellent for studying, legal reading and any dense document set. The Audio Overview feature, which turns your notes into a two-host podcast, is a surprisingly effective way to review material.
