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.
A technical/product release from Google (major platform) expands LLM capabilities and cross-product integration with Search and Workspace, affecting enterprise AI workflows, data governance, and potential downstream use in marketing and analytics.

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 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.
Google updates NotebookLM with Gemini 3.5, new research features
Google announced an update to its NotebookLM research tool on June 8, 2026, making Gemini 3.5 the default model and adding Antigravity-powered software skills. The update lets users start a chat about a project and have NotebookLM suggest and pull sources (including non-English primary sources) via its research skills and Google Search to build a knowledge base without requiring users to supply documents first. NotebookLM now supports detailed instruction-driven outputs, editable generated results, provenance-style chat steps showing how answers were reached, and exports to multiple formats (images, documents, structured data, Excel/PowerPoint). The features are available to Google AI Ultra users and Workspace business customers with AI Ultra and AI Expanded Access, with wider rollout planned.
