Gemini Notebook

Gemini Notebook, formerly NotebookLM, is Google’s research and thinking partner grounded in your own sources. Upload PDFs, docs, YouTube links, or web pages, then chat over them with cited answers, or turn them into slide decks, mind maps, Audio Overviews, and Video Overviews. New study tools add quizzes, flashcards, and lessons from your material. The free plan includes 100 notebooks with 50 sources each, and usage limits are compute-based, refreshing every five hours up to a weekly cap.
