5.7 NotebookLM

NotebookLM is an AI research and note-taking assistant from Google. Instead of answering from the whole internet, it focuses on documents you upload — PDFs, notes, slides — and answers questions using only those sources. This 'grounding' keeps answers tied to your material and reduces made-up information.

For example, a student preparing for an exam can upload their lecture notes and textbook chapters, then ask NotebookLM to explain a topic or quiz them — and every answer is based on their own course material. It can even create an audio overview that sounds like a podcast.
