Overview
NotebookLM is an AI-powered research and knowledge management platform developed by Google. Unlike traditional AI assistants that rely on general internet knowledge, NotebookLM allows users to upload their own documents, PDFs, websites, notes, transcripts, and research materials, then ask questions and generate insights based specifically on those sources. In July 2026, Google renamed NotebookLM to Gemini Notebook. It remains the same standalone product, now more deeply connected to Google’s broader Gemini ecosystem.
Recent Updates
Key takeaway: Google renamed NotebookLM to Gemini Notebook in July 2026. The same standalone research product now includes a secure cloud computer inside every notebook that can write and run code for source-grounded analysis, and Google has begun adding automation for feeding sources into notebooks.
In July 2026, Google renamed NotebookLM to Gemini Notebook as part of a broader push to bring its products under the Gemini brand. The product itself remains a standalone research and knowledge-management tool where users upload their own documents and ask questions grounded in those sources. Google says the change comes with deeper integration across the Gemini ecosystem and a secure cloud computer inside every notebook, letting the tool write and execute code natively against uploaded materials for data work and analysis.
In August 2026, Google began rolling out a new “Add a source to Gemini Notebook” step for Google Workspace Studio, which lets organizations automate the process of adding text, Google Drive files, and other materials to a notebook. The feature is being made available to Business, Enterprise, and Education customers. For students and researchers, the NotebookLM name still points to the same product, but expect the tool to keep appearing under the Gemini name as Google expands it across its ecosystem.
