Google makes Gemini persistent

Google is turning Gemini from a chatbot you visit into a workspace you come back to. The new feature is called notebooks, and it gives Gemini a saved project space where chats, files, and instructions stay together instead of disappearing into one long history. (blog.google) A notebook in Gemini works like a folder with memory. You can move old chats into it, upload documents and Portable Document Format files, and set custom instructions so Gemini answers with the same project context every time. (blog.google) The bigger move is that these notebooks sync with NotebookLM, which is Google’s research tool for working from source documents. If you add a source in Gemini, it shows up in NotebookLM too, so one project can move between chat mode and research mode without being rebuilt. (blog.google) That matters because NotebookLM already does jobs Gemini does not, including Video Overviews and Infographics built from your source set. Google’s example is a student dropping class notes into a notebook in Gemini and then opening the same notebook in NotebookLM to make a cinematic video summary. (blog.google) Google had already linked the two products once before. On January 27, 2026, Google Workspace users got the ability to add a NotebookLM notebook as a source inside a Gemini chat, but that still treated NotebookLM as an attachment, not as Gemini’s own home screen for a project. (workspaceupdates.googleblog.com) This update goes further by making the notebook itself a first-class object inside Gemini. Google says Gemini uses the notebook’s handpicked sources alongside its own tools and web search, which means the chat is now anchored to a saved pile of material instead of a blank prompt box. (blog.google) The rollout is narrow at first. Google says notebooks are arriving this week on the web for Google Artificial Intelligence Ultra, Pro, and Plus subscribers, with mobile access, more countries in Europe, and free users coming in the next few weeks. (blog.google; engadget.com) The limits also show who Google thinks this is for. Thurrott reports that free users can have 100 notebooks with 50 sources each, Google Artificial Intelligence Plus raises that to 200 notebooks with 100 sources, Google Artificial Intelligence Pro goes to 500 notebooks with 300 sources, and Google Artificial Intelligence Ultra keeps 500 notebooks but lifts sources to 600 each. (thurrott.com) The awkward gap is that Google already offers Gemini and NotebookLM to many school and work accounts, including Google Workspace for Education users of all ages, but this new notebooks rollout is starting on consumer-style Google Artificial Intelligence plans instead of managed workplace packaging. That leaves companies and schools waiting for the admin controls, compliance language, and licensing path they usually need before turning on a feature across an organization. (knowledge.workspace.google.com; workspaceupdates.googleblog.com; blog.google) What Google is really building here is a shared memory layer across its artificial intelligence products. Chatbots are good at one conversation, but notebooks give Gemini a place to keep the documents, rules, and past exchanges for a project that lasts longer than one tab. (blog.google; pcmag.com)
