NotebookLM

verified star 4.6

Google's AI research notebook: upload sources and get grounded answers, summaries and audio overviews.

About NotebookLM

NotebookLM flips the usual AI pattern: instead of answering from the open internet, it reasons only over the sources you upload — PDFs, docs, slides, links — and cites them precisely.

Its viral Audio Overviews turn any document set into an engaging two-host podcast, making dense material genuinely listenable.
