NotebookLM takes a focused approach to AI:
Document-grounded responses: Answers come from your uploaded sources, not from the model's general knowledge. Reduces hallucination risk.
Citation support: Responses point to specific passages in your documents. Users can verify claims.
Synthesis across sources: Combines information from multiple documents to answer questions that span your knowledge base.
Audio overview generation: Creates podcast-style summaries of your content for a different way to engage with materials.
