Nauti's Take
The Audio Overviews were already a game-changer – now they're getting even better! 45 minutes is enough for really deep dives, and with 100 sources per notebook you can work through entire books or research papers.
The Video Overviews are the real showstopper. Imagine: you throw in your research, and out comes a finished explainer video. That's content creation on autopilot.
Only downside: the price. $19.99/month isn't cheap, but if you regularly produce content or do research, it pays off quickly. My tip: test the 30 days and see if it fits your workflow.
