NotebookLM

Overview

NotebookLM inverts the usual chatbot arrangement. Instead of asking a model that knows everything and hoping it does not invent things, you upload your own sources — documents, PDFs, Google Docs, pasted text, links, YouTube videos — and it answers strictly from those, with inline citations pointing back to the passage it used. That grounding is the whole product, and it dramatically reduces the hallucination problem that makes general chatbots unusable for serious research. It will also generate study guides, briefing docs, timelines and an oddly compelling Audio Overview: a synthetic two-host podcast discussing your material, which is far more useful for revision than it has any right to be. Limits apply. It is Google-account-bound and cloud-only, so your sources go to Google — a non-starter for confidential material in some organisations. There are caps on sources and notebook size. It is a research and comprehension tool, not a writing tool or a note-taking system, and it does not manage a knowledge base over time. Free, and remarkable for the price.
