Overview
- Google, which announced the feature Wednesday, began rolling it out on the web to AI Ultra, Pro, and Plus subscribers.
- Notebooks let you group chats, files, and custom instructions for a project so Gemini can answer with that material as context.
- Anything you add in Gemini appears in NotebookLM and vice versa because the two now share one auto-updating knowledge base.
- Users get an Add to notebook option on chats plus controls to use notebook memory and set response style, with sources pulled from Drive, websites, PDFs, YouTube links, and pasted text.
- Access will expand in the coming weeks to mobile, more countries including parts of Europe, and free users, and higher tiers unlock more sources and NotebookLM outputs like Video Overviews and Infographics.
