Descriptions:
Jeff Su, a former Google employee, delivers a comprehensive update on NotebookLM following its wave of new features in early 2026 — noting that the tool has reportedly surpassed Gemini itself in usage and interest. The video is structured around what NotebookLM is still uniquely suited for (grounded, multi-format document analysis where hallucinations are unacceptable), followed by a tiered breakdown of which new Studio panel tools are actually worth using.
Su walks through the full three-panel workflow — Sources for ingestion, Chat for querying, Studio for output generation — using a realistic example of building a Gemini adoption proposal for the Asia-Pacific region. He distinguishes clearly between fast research (returns a source list for manual review) and deep research (synthesizes a full report automatically), recommending against deep research in favor of tools like Gemini, ChatGPT, or Claude for that job. The Studio panel receives the most attention: Su covers the Reports tool, which generates tailored briefing docs and competitive analyses directly from uploaded sources using AI-inferred prompt suggestions, and the Slide Deck tool, which produces complete presentations but exports slides as images rather than editable PowerPoint elements — a limitation he addresses with a practical workaround.
Throughout, Su provides honest tier classifications and specific prompt templates, making the video a practical reference for anyone using NotebookLM for professional research, financial analysis, or content production workflows.
