Gemini Notebook (formerly NotebookLM)
Turns any document or video into a source you can question with citations, ideal when you're drowning in research material.
What it does
Gemini Notebook is Google's research tool, renamed from NotebookLM in July 2026. You upload documents, videos, or web links as sources, and it answers questions using only what you gave it, with citations pointing back to the exact passage. Every answer names its source; that accountability is the whole point. Beyond chat, it turns your sources into an audio overview, a slide deck, a mind map, a quiz, or a data table. The newest addition is a secure cloud computer built into every notebook, so paid tiers can now run code against your sources instead of just summarizing them.

Who this helps
You have a stack of client research, competitor teardown notes, or long-form transcripts and need one place to ask questions against all of them at once.
You want to turn a single long document into five different formats (audio, slides, quiz) without redoing the work by hand.
You are prepping for a call or a video on a topic you do not know well and need a fast, source-checked crash course.
You manage a team and need shared notebooks that keep everyone answering from the same source material instead of scattered notes.
What it replaces
If you are paying a research assistant to read through source material and summarize it before a call or a piece of content, this does most of that job in minutes instead of hours. It replaces roughly the summarizing and study-guide half of a $15–25/hour research VA's workload, not the judgment calls about what's worth including.
