NotebookLM

NotebookLM is a source-grounded AI research and note-taking assistant from Google, powered by Gemini, that answers questions strictly from documents you upload (PDFs, Google Docs, web pages, audio) and cites the exact passage behind each answer. It can turn those sources into summaries, study guides, mind maps, audio and video overviews, and other artefacts. It suits founders, researchers, and teams who want to interrogate a defined set of their own materials rather than the open web.
