How to add YouTube videos and playlists to NotebookLM (Gemini Notebook)
Read the transcript

Here's how to add YouTube videos to Gemini Notebook, formerly NotebookLM. One video, a channel, a playlist, or a page of search results. Open any video on YouTube.

Kortex adds a NotebookLM button, right beside Like and Share. Click it. Choose Create New Notebook, or Use Existing Notebook to add the video to one you have.

Your notebooks are listed, and the one the video fits best sits on top, marked Suggested. If that notebook already has the video, Kortex warns you first. You can add it anyway, or cancel.

The same button works on a channel, a playlist, or search results. A channel sends its uploads, newest first. A playlist goes in order.

Search results keep your filters. One click starts a batch of up to 50 videos. The button says what it's doing, then how many videos went in.

Then your notebook opens, with each video as its own YouTube source. Once Google has processed them, ask a question. The answer cites the videos.

Add Kortex to Chrome, and any video is one click from your notebook.

  1. Open the YouTube page

    Go to a video, a playlist, a channel page or a search results page. Set any search filters first. Kortex imports the results as filtered.
