In more detail
NotebookLM has two tiers. Free: 100 notebooks, 300 sources per notebook, 50 daily queries, 3 Audio Overviews per day. Plus: 500 notebooks, 1,500 sources per notebook, 250 daily queries, 15 Audio Overviews per day, plus Audio Overview customization, premium Gemini models, and shared/team notebooks. Plus is bundled into Google One AI Premium at $19.99/month, which also includes Gemini Advanced. For most users, the free tier is generous enough that limits don't become a daily issue. Heavy researchers tend to upgrade to Plus after a few months.
