Overview of Personal Intelligence in NotebookLM
The latest testing builds of Google NotebookLM reveal a new Personal Intelligence option. This feature aims to ground the tool’s responses in the sources you add while also learning from your chat interactions to better understand your preferences.
How Personal Intelligence Works
According to strings uncovered by TestingCatalog, Personal Intelligence will analyze your chats and generate a customizable persona. An example persona reads:
"You are a researcher interested in AI and machine learning. You prefer concise, technical explanations with code examples when relevant."
This persona can be edited, allowing users to correct any inaccurate assumptions about their workflow.
User Control and Settings
Personal Intelligence can be toggled in two places:
- Globally in the Settings menu.
- Individually per notebook, giving granular control over where the feature is active.
These toggles suggest Google wants to let users decide whether the AI learns from all their notes or only selected notebooks.
Potential Benefits
- More context‑aware responses by referencing past chats.
- Tailored explanations that match your preferred style (e.g., concise, technical, with code).
- Reduced need to repeat preferences across notebooks.
Rollout Timeline
Personal Intelligence is still in the testing phase, so a public release may take some time. Google has been rapidly iterating on NotebookLM, so the feature could arrive sooner rather than later.
Community Feedback
The NotebookLM community is encouraged to share opinions on the new feature. Feedback will help shape how Personal Intelligence evolves before it becomes widely available.
