How do I import sources into Gemini Notebook?
Open Gemini Notebook (formerly NotebookLM), create or open a notebook, and click Add Source to import PDFs, web URLs, YouTube videos, Google Docs, or pasted text natively. To capture from AI chats, social media, and the web faster, install Gemini Notebook Toolkit — its Chrome extension adds one-click and bulk capture from 30+ platforms.
In more detail
Gemini Notebook accepts sources two ways. Natively: open a notebook, click Add Source, and upload PDFs (up to 200 MB / 500K words), plain text and Markdown, Google Docs and Slides, web URLs, YouTube videos (auto-transcribed), audio files, or pasted text — up to 300 sources per notebook on the free tier (1,500 on the paid tier). For everything the native importer misses — ChatGPT, Claude, Gemini, and Perplexity conversations, Reddit threads, X posts, LinkedIn, arXiv, PubMed, GitHub, and any web page — install Gemini Notebook Toolkit. Its Chrome extension adds a capture button right where you are reading, so you can send a page into Gemini Notebook in one click, or bulk-capture several sources at once into the notebook you choose, with formatting preserved.
