Given that NotebookLM is still a relatively new tool, the team has been constantly rolling out updates and features to improve the overall experience and iron out any quirks based on user feedback. If you’ve been following XDA’s NotebookLM coverage (or any other outlet’s, really), you’ve probably seen the major updates get plenty of attention, like Video Overviews, Flashcards and Quizzes being introduced, and even Gemini’s Deep Research feature being spotted in testing.
