Google folds NotebookLM into Gemini
Google has started integrating NotebookLM-style research and presentation features directly into Gemini, creating persistent project workspaces that sync chats, files and research. ( ) The company is also experimenting with free, no-billing Gemini API keys for developers and expanding Canvas to generate slide decks from prompts or uploads. ( )
Google is turning Gemini into a project workspace by adding notebooks that sync chats, files and research with NotebookLM. (blog.google) Google announced the feature on April 8, 2026, and said notebooks are rolling out on the web first to Google AI Ultra, Pro and Plus subscribers. In Gemini, users can move old chats into a notebook, add documents and portable document format files, and set custom instructions for a project. (blog.google) The notebook then syncs with NotebookLM, Google’s research app for working from a set of chosen sources instead of a blank chat box. Google said files added in one app appear in the other, so a notebook started in Gemini can use NotebookLM features such as Video Overviews and Infographics. (blog.google) The change pulls a standalone Google product deeper into the company’s main artificial intelligence assistant. Google had already added NotebookLM as a source inside Gemini late last year, and the new notebook layer keeps that research context attached to longer-running work. (blog.google) Google is also pushing Gemini beyond chat into document and slide creation. In March, the company said Gemini in Google Docs, Sheets, Slides and Drive would start getting new drafting, analysis and presentation features for Google AI Ultra and Pro subscribers. (blog.google) A related Canvas feature lets users generate a slide deck from a prompt or an uploaded source and then export it to Google Slides for editing. Google introduced presentation generation in the Gemini app through Canvas in October 2025, and outside reports say the feature is now drawing wider attention as the notebook rollout expands. (workspaceupdates.googleblog.com; nationaltoday.com) For developers, Google’s Gemini application programming interface still includes a free tier that does not require billing to create a project and key. Google’s billing documentation says new accounts begin on the Free Tier, while paid access requires linking a billing account and prepaying at least $10 to unlock higher limits and advanced models. (ai.google.dev) That leaves Google with the same pitch across consumers, office workers and developers: keep your sources, drafts and model access inside one Gemini system. The notebook rollout is still limited by subscription tier and web availability, but it shows where Google wants Gemini to live next. (blog.google; ai.google.dev)
