NotebookLM
Google's source-grounded research notebook with audio overviews
Part of this entry was LLM-drafted and is being polished.
NotebookLM lets you upload sources (PDFs, docs, links, videos) and ask questions strictly grounded in those sources — no LLM-trained knowledge leaks into answers. Audio Overview turns sources into a podcast-style two-host discussion. Free for personal use.
Editor's verdict
Best free research tool from a major lab. Source-grounding is the differentiator — answers stay on the rails of what you uploaded. Audio Overview is genuinely magical for quick understanding. Limit: only as good as your sources; missing context isn't filled by world knowledge. The right tool for serious research where citation discipline matters.
