Description
You have multiple research papers, lecture slides, and articles to review for a deadline. You want to extract the key points, generate summaries, and maybe listen to a summary while commuting. NotebookLM helps by letting you upload your materials, ask questions about them, and get audio overviews—all based on your own sources, not general web info.
