The YouTube to NotebookLM Chrome extension is remarkably useful. It’s free. And simple. Download the Chrome Extension to enable it in your browser. You’ll then see an Add to NotebookLM button on YouTube. You can then pull in videos from any YouTube channel, playlist, or search query into a NotebookLM notebook.

You have the option of adding to an existing notebook or creating a new one. It takes just a minute or two to populate the notebook with the videos. You can then watch the videos inside your notebook, read the transcripts, or, best of all, query the transcripts from all of those videos. It won’t work with private videos, or videos without talking.

If you’re on a free plan, you’ll get to import up to 50 videos at a time — the max number that fits in a free notebook. On a paid plan, you can pull in 300 videos into a single notebook.

It’s a terrific tool for learning. You basically get a new searchable knowledge base. I used it to pull in my own YouTube videos to to analyze patterns across my videos and to see what I could do better. I was also able to generate infographics and summary reports about my videos, a data table, and a mind map. If you want, you can generate an audio or video overview of a YouTube channel, or even create slides from your own YouTube video(s).

It’s particularly useful if you’re eager to learn from a particular person or channel on Youtube, or if you want to analyze a company, competitor, or complex subject for work, for an interview, or just out of your own curiosity.
