Google's NotebookLM is now Gemini Notebook

NotebookLM was built around a narrow premise: the user supplies the sources, and the AI answers from them. PDFs and Google Docs were the typical inputs, and summarizing and analyzing that material was the core use.

Google renamed the product to Gemini Notebook in July 2026, and the body frames that rename as a turning point rather than a simple label change. The June 2026 addition of in-notebook code execution, plus expanded output formats such as graphs, spreadsheets and slide decks, shows the product moving from reading toward producing. Updates in August and September 2026 around usage limits and sources suggest the practical terms of use are still being adjusted.

The stakes appear to hinge on whether these additions make Gemini Notebook a place where work is finished, not just understood. For people who already rely on it for document-heavy tasks, the test is likely whether the newer analysis and output features hold up in daily use, while the changing usage limits and source options will shape how much of that work can actually be done there.
