Our Verdict
🏆 Winner: NotebookLM
For research grounded in specific documents, NotebookLM wins - it answers from your uploaded sources with citations, dramatically reducing hallucination risk. ChatGPT wins for general-purpose tasks, creative work, coding, and anything that isn't about reasoning over a specific document set. If you're a student or researcher working with your own material, NotebookLM is the better specialized tool. For everything else, ChatGPT's breadth gives it the edge.
