NotebookLM 2.0 — Agentic Upgrade
Gemini 3.5 + Antigravity turns NotebookLM into an autonomous research agent: secure code execution, start-from-scratch web sourcing, and one-click Studio Panel exports.
See the deep-dive ↓NotebookLM’s biggest 2026 update landed June 8: the agentic upgrade on Gemini 3.5 + Antigravity, adding per-notebook code execution, start-from-scratch web sourcing, and Studio Panel exports. Earlier milestones: Gemini 3 (Dec 2025), 1M-token context for all plans (Jan 2026), and the Ultra split (May 2026).
NotebookLM 2.0: the June 2026 Agentic Upgrade
The single biggest leap of the year. NotebookLM crosses from a "chat with your documents" assistant into a secure, cross-source autonomous research agent — one that writes and runs code, sources the open web on its own, and exports finished files. Here's the whole arc, the headline numbers, and every shipped capability.

Every shipped capability
Gemini 3.5 + agentic logic
Native Antigravity framework brings multi-step analysis and far fewer hallucinations — plus a visible reasoning tree that shows the model's steps live instead of a loading spinner.
Secure cloud computer
Every notebook gets a sandboxed environment that writes and executes code behind the scenes — exact arithmetic, data parsing, and math verification grounded in your own sources. Full code-execution guide →
Start from scratch
Open a blank notebook and type an idea. NotebookLM deploys Google Search autonomously, compiles relevant pages, and pulls them in as cited, active sources. Full start-from-scratch guide →
Studio Panel & exports
A library of 100+ skills turns messy notes into polished files via chat: PDF, Word, PowerPoint, Excel, Markdown, CSV/JSON, and vector infographics. Full format table below.
