Google adds NotebookLM Notebooks to Gemini app
Google has integrated NotebookLM’s Notebooks feature into the Gemini app, letting users create and manage personal knowledge notebooks inside Gemini and continue projects in NotebookLM with synchronized access. Users can upload up to 100 sources at no extra cost and reuse integrated sources across both products. NotebookLM already supports audio and video overviews, including Cinematic Video Overviews for storytelling. The initial rollout targets the web for AI Ultra, Plus and Pro subscribers; mobile access, EU users, Workspace accounts and non-subscribers are expected in the coming weeks. Josh Woodward, Google VP for the Gemini App, Google Labs and Google AI Studio, described the integration as a “second brain” enabling personalized context and project continuity across Google products.
Feature-level technical release from a major platform (Google) that expands Gemini’s capabilities and cross-product synchronization; relevant to AI-driven workflows, content understanding and potential future integrations with Google’s product ecosystem.

Google renames NotebookLM to Gemini Notebook
Google renamed NotebookLM to Gemini Notebook and is expanding its integration across Google services, including the Gemini app and forthcoming access via AI Mode in Google Search. The tool—originally Project Tailwind and used by over 30 million people and more than 600,000 organizations—now makes each notebook a secure container and adds in-notebook code execution and advanced data-analysis capabilities. Those features, previously tied to Google AI Ultra and certain Workspace business plans, will roll out to Google AI Pro subscribers in the coming weeks. Separately, reports (CNBC citing Bloomberg) say the next flagship model, Gemini 3.5 Pro, is delayed by several months and prompted about a 4% drop in Alphabet shares; Google says it is testing Gemini 3.5 Pro and other models with partners but has not confirmed a launch date.
Google Connects Gemini to NotebookLM
Google’s NotebookLM (part of Google AI) has received a set of product updates — notably prompt-based slide revisions — alongside deeper integration with Gemini. NotebookLM emphasizes sole-sourced answers (responding only from user-provided sources), supports up to 50 sources across formats, and can generate 10+ output types including slide decks, infographics, podcasts, mind maps and data tables. The new prompt-based slide revision workflow turns slide generation into an iterative collaboration loop. NotebookLM integrates with Google Drive and Gemini (Gems auto-sync to notebooks), and community MCP servers exist to connect external models. The author reports NotebookLM has 48 million monthly visits and 120% quarter-over-quarter user growth in Q4 2024. The guide outlines research-to-product workflows and implications for faster marketing content creation and AI prototyping.
Google Expands Gemini Notebook with Visible Thinking Steps
Google has renamed and expanded NotebookLM into Gemini Notebook, a more integrated research workspace that connects the Gemini app, Google Search and Google Workspace. New user-facing features include expandable "thinking steps" for eligible Google AI Ultra and Pro subscribers, in-notebook code execution, and continued citation-backed outputs (Audio Overviews, Mind Maps). The rollout is phased (initial access for Google AI Ultra and Workspace AI Ultra Access, then Pro on the web) with mobile expansion planned. Google says uploaded sources remain private and are not used to train models; the company frames thinking steps as experimental and an inspection aid rather than proof of correctness.
