NotebookLM

Google AI research and learning assistant grounded in user-provided sources.

NotebookLM fits research, learning, and decision workflows where a team wants AI summaries, questions, audio-style explanations, and synthesis grounded in uploaded or selected source material rather than open-ended model memory.
