Launching today to “a small group of users in the US,” according to a Google blog post.

The core of NotebookLM seems to actually start in Google Docs. (“We’ll be adding additional formats soon,” the blog post says.) Once you get access to the app, you’ll be able to select a bunch of docs and then use NotebookLM to ask questions about them and even create new stuff with them.

Google offers a few ideas for things you might do in NotebookLM, such as automatically summarizing a long document or turning a video outline into a script. Google’s examples, even back at I/O, seemed primarily geared toward students: you might ask for a summary of your class notes for the week or for NotebookLM to tell you everything you’ve learned about the Peloponnesian War this semester.
