Changelog — what’s new on NotebookLM Guide
Everything we add, rewrite, or fix on notebooklm-guide.com, newest first — new guides and tools, multilingual pages, and behind-the-scenes improvements. Looking for NotebookLM product news instead (new features Google shipped)? That lives on the NotebookLM Updates page.
July 2026
Tools Hub launched
A new interactive workspace at /tools/ — Slide OS (presentation blueprint generator), the NotebookLM Prompt Generator v3, and the GEO/AEO Prompt Optimizer v5. All free, all in your browser.
Short Video Overviews guide
A full walkthrough of NotebookLM’s new 9:16 vertical, ~60-second videos — how they work, how they differ from long Video Overviews, and the prompts that make them land.
Common Problems 2026
A troubleshooting guide for the questions people actually search: when daily limits reset, why you can’t add more sources, free-tier gaps, generation speed, and upload errors.
German site (/de/) launched
Fifteen core guides now available in Deutsch, with proper hreflang pairing to their English originals.
Chinese Antigravity deep-dive
A Simplified-Chinese page explaining the Gemini 3.5 + Antigravity agentic upgrade and how it divides labor with Nano Banana 2 Lite.
Antigravity vs Nano Banana 2 Lite
Added a “brain vs renderer” section clarifying that Antigravity is the agentic backend (reasoning + code) while Nano Banana 2 Lite handles video rendering — complementary, not the same system.
Setup Guide merged into Quick Start
Consolidated two overlapping getting-started pages into one canonical Quick Start, with a permanent redirect so old links keep working.
Audio guide consolidated into Podcast Automation
Merged the Audio & Podcast Guide into the Podcast Automation page and repointed internal links directly, with the old URL preserved as a redirect.
June 2026
Gemini 3.5 + Antigravity update coverage
Full breakdown of NotebookLM’s June 8 agentic upgrade: the per-notebook cloud computer, 100+ software skills, agentic sourcing, and new exports.
Code Execution & Start From Scratch guides
Two dedicated guides for the agentic features — running code on your sources, and building a source library from a blank notebook via chat.
Direct Answers + FAQ schema across the library
Added a concise “Direct Answer” block and paired FAQPage structured data to 86 guides, so they’re easier for both readers and AI search engines to quote.
Related reading + inline tool prompts
Topic-cluster “related reading” modules and a mid-article link to the Prompt Generator now appear across the guide library.
Crawlability, analytics & link hygiene
Added an llms.txt for AI crawlers, Bing verification, analytics coverage across 220+ pages, a site-wide broken-link and 404 cleanup, and trailing-slash URL canonicalization.
