NotebookLM is a tool for understanding, built with Gemini 1.5. When you upload your sources, it instantly becomes an expert, grounding its responses in your material and giving you powerful ways to transform information. And since it’s your notebook, your personal data is never used to train NotebookLM. Millions of people are already using NotebookLM to understand and engage with complex information, and today we’re removing the product’s “Experimental” label and releasing another round of features.
