NotebookLM just shipped a feature that pulls back the curtain on its Studio outputs. With the new Source Attribution view, every artifact you generate now carries a visible recipe: the prompt that produced it, plus the exact subset of sources NotebookLM grounded the answer in. Tap the new Iterate button and you can edit that recipe directly to regenerate a tuned version.

The update lands in a tool that already leans hard on provenance. NotebookLM is a source-grounded AI research assistant built by Google and powered by Gemini that uses Retrieval Augmented Generation (RAG) to provide responses backed by web citations, and the Studio panel offers one-click multimedia generation to transform source data into interactive formats like Audio and Video Overviews, Mind Maps, Slide Decks, Infographics, Data Tables, and academic tools such as Quizzes and Flashcards. Until now, those outputs arrived as finished objects with no easy way to see what produced them.
