Google says the system includes more than 100 curated software skills that can be applied to information stored inside a notebook. In internal evaluations, the upgraded version achieved an average win rate of more than 65% across five core testing categories compared with the previous system. The company reported a 69.9% win rate in large-document analysis and a 78.2% win rate in web research and source discovery tasks.
The release also expands the types of content NotebookLM can generate. Users can now create PDF reports, spreadsheets, presentations, charts, data visualizations, images, and structured data files directly from notebook sources. Generated assets can be downloaded from the studio panel and edited after creation.
New export options include PDF, DOCX, Markdown, text files, CSV, JSON, XLSX, PPTX, PNG, SVG, JPG, and GIF formats. Google said additional output formats are planned in future updates.
Another major change is how users begin research projects. Previously, NotebookLM worked best when users supplied their own collection of sources. The platform can now help build a source repository from an initial question or idea, including finding relevant material through Google Search and adding those sources to a notebook.
Google said users remain in control of which sources are included, and all information added to notebooks continues to be attributed to its original source.
The company highlighted several use cases for the new capabilities. Researchers can combine data from multiple sources, perform analysis with code, and generate charts and reports. Technical teams can convert complex documentation into guides, presentations, and project roadmaps. Small business owners can analyze sales and advertising data to evaluate marketing performance and expansion opportunities.
The upgrades represent Google’s most significant expansion of NotebookLM’s research workflow capabilities since the product launched from Google Labs three years ago. Rather than focusing solely on summarization and document analysis, the platform is moving toward helping users discover sources, analyze information, and generate finished research outputs from a single workspace.
