Visit NotebookLM →About NotebookLM
NotebookLM is Google's AI research and synthesis tool, designed for analyzing your own documents rather than searching the web. You upload sources — PDFs, Google Docs, YouTube links, audio files, EPUB books — and NotebookLM becomes an expert on that material, answering questions, generating summaries, and creating study aids grounded entirely in your uploaded content.
The Audio Overview feature generates a realistic two-host podcast discussion of your sources — one of the most distinctive AI output formats available. It was one of the first features to go viral and remains a core differentiator.
2026 updates are substantial. Cinematic Video Overviews, launched March 2026, generate fluid animated narrative videos from your sources — a significant upgrade over static slides with voiceover (currently available on Google AI Ultra plan). Slide editing now allows targeting individual slides with prompt-based instructions rather than regenerating the entire deck. EPUB file support added. NotebookLM integrated into Google Classroom for educators in higher education.
NotebookLM is free with standard limits. NotebookLM Plus, available through Google AI Pro at $19.99/month, unlocks higher usage thresholds, more sources per notebook, additional chat queries, expanded study tools, and Cinematic Video Overviews.
Best for students, researchers, lawyers, and analysts who need to synthesize and interrogate large bodies of their own documents rather than search the open web.
