About
Google's NotebookLM is a research assistant that grounds every answer in documents, links, and notes you upload. Distinctive features include the Audio Overview that turns a notebook of sources into a two-host podcast in one click, and Mind Map / Briefing Doc views that synthesise long-form material. Free tier covers most personal use; paid Plus tier ships with Workspace.
Best for: Founders, researchers, and operators who work with primary sources — investor decks, customer interviews, technical docs — and want answers that cite back to the source. The Audio Overview alone turns a long doc-pile into a 10-minute podcast you can listen to on a walk.
