Duplicate Any Shared or Featured NotebookLM Notebook

When someone shares a NotebookLM notebook with you — or when you open a Featured/public notebook — you can view it, but you can't add new sources, generate infographics, create Audio Overviews, or run Studio tools. Kaptex will add a "Duplicate to my account" button that clones the notebook into your own NotebookLM so you own it fully. Add sources, generate content, and build on top of what was shared.
