It’s easy to be blown away by the results when you first try using Gemini Notebook (formerly NotebookLM) or ChatGPT Learn to build study materials from scratch. You can feed these AI-powered learning assistants source material, like notes, textbooks, websites, or videos, and they’ll handle the creation. Making study guides, practice tests, flashcards, and other learning tools has never been easier thanks to Gemini Notebook and ChatGPT Learn — but that doesn’t mean it’s the best way to master a topic before an exam.
