NotebookLM
Google’s notebook product that answers from sources you add.
Tasks: Research Notes and workspace
NotebookLM is Google’s notebook assistant. The official product URL is notebooklm.google.com (when checked on 10 November 2026 it redirected to notebook.google.com). Official descriptions emphasize answers grounded in sources you upload or add.
Google’s own pages cover supported file types, account requirements, and privacy wording. We do not add unofficial limits here.
It fits work where you already have a packet of documents and want questions answered against that packet. The quality still depends on what you added and on your own reading of those sources.
