This means NotebookLM can now automatically pull in relevant external sources, cross-reference data, and synthesize findings into layered reports complete with summaries, tables, and cited references. The AI doesn’t just summarize—it connects the dots, uncovering insights that might otherwise be missed in manual research. For example, a user analyzing multiple AI startups can now have NotebookLM gather quantitative data from various sources, organize it into structured tables, and highlight key trends or gaps.
