Overview
- Google announced the update on Monday, June 8, 2026, making Gemini 3.5 the default model and adding Antigravity as the tool that lets NotebookLM write and run code in a secure cloud environment.
- Each notebook now includes a per-notebook “secure cloud computer” plus more than 100 curated software skills that enable data analysis, reproducible code runs, and visible step-by-step reasoning in chat.
- NotebookLM’s chat can automatically search the web with Google Search to suggest and add sources to a knowledge base, including multilingual primary sources, replacing the old requirement that users upload all materials themselves.
- The tool can export generated work in many downloadable, editable formats — charts (PNG/SVG), documents (PDF/DOCX/Markdown/text), images (Nano Banana PNG/JPG/GIF), structured data (CSV/JSON), XLSX and PPTX — to support end-to-end research and business workflows.
- Google reports material evaluation gains versus its prior baseline (average win rates above 65% and up to 78.2% in advanced web research) and is rolling the features out first to AI Ultra and Workspace business customers while noting these metrics come from its own side-by-side tests.
