Teknozip – Google’s Gemini and NotebookLM integration, designed to streamline research and note-taking, is now accessible to all users, regardless of subscription status. This development marks a significant shift, opening up powerful AI-assisted learning tools to a wider audience.
Previously, the seamless syncing between Gemini and NotebookLM was a perk reserved for paying subscribers. This integration allows users to leverage Gemini’s AI capabilities to analyse and summarise documents stored in NotebookLM, and conversely, save Gemini research directly into NotebookLM notebooks.

The announcement, made via NotebookLM’s X feed, confirms that free-tier users can now experience this notebook syncing feature when using Gemini on the web. This move comes shortly after the initial release of the feature for subscribers, offering a welcome opportunity for non-paying users to explore its potential.

While the free tier provides access to the core functionality, limitations exist. Free users are restricted to 50 sources per notebook, whereas AI Plus subscribers enjoy 100 sources. For power users, the Pro and Ultra tiers unlock even greater capacity, with 300 and 600 sources per notebook respectively.
However, the free tier offers ample opportunity to evaluate the integration’s value and determine if a paid subscription is warranted. This democratisation of access allows individuals to experience firsthand how Gemini and NotebookLM can enhance their research, writing, and overall learning process.
| Feature | Free Tier | AI Plus | Pro | Ultra |
