NotebookLM
NotebookLM is Google's hosted research notebook — you upload sources (PDFs, Google Docs, URLs, YouTube videos, audio files), and a Gemini-backed assistant answers questions grounded in your sources only. The standout feature is Audio Overviews — a podcast-style conversation generated from your notebook that two AI hosts walk through. Free tier is generous; NotebookLM Plus raises the limits and adds features; NotebookLM Enterprise ships through Google Workspace with admin controls and data residency. Sush has heard a lot of good things but has never personally used it. Sourced from notebooklm.google.com and blog.google/technology/ai.
- NLM.1 NotebookLM, plainly sourced
What NotebookLM is — a source-grounded research notebook from Google. You upload PDFs, Google Docs, web URLs, audio files, even YouTube videos; chat is grounded in only those sources. Plus the Studio panel (Audio Overviews, Video Overviews, Mind Maps, Reports), tier breakdown, and the privacy story.
- NLM.2 NotebookLM — what people actually use it for sourced
Twelve real-world NotebookLM use cases drawn from Google's blog, case studies, and the official help centre — academic research with citations, biography research, sales call analysis, hyperlocal journalism, study aids, presentation creation, audio-first learning, and fiction worldbuilding.
- NLM.3 NotebookLM Enterprise sourced
NotebookLM Enterprise on Google Cloud — $9 USD per licence per month, your files stay inside your GCP project, data regionalisation honoured, no human review, no model training. VPC Service Controls, IAM, CMEK. How it differs from the consumer / Workspace tiers.
