Bookshelf for NotebookLM

Ruxandra Mazilu, Akshay Kumar, and south looked at Google NotebookLM—Google's AI research tool that's been blowing up since they added audio overviews—and said "this is great, but I can't find anything." So they built Bookshelf, a browser extension that adds folders, search, and sync to NotebookLM. It's the kind of small, scrappy tool that makes you realize Google's product team was too busy shippingGemini to worry about organization.

Bookshelf is open source, lives on GitHub, and if you're one of the millions of people dumping PDFs and research into NotebookLM every week, this is probably the first extension you're going to install. Simple tools that solve one specific pain point tend to stick around. Based in the cloud, probably building late into the night.
