NotebookLM gets a smarter brain and cloud power
Google has upgraded NotebookLM to use Gemini 3.5, bringing more accurate, reliable responses and smoother performance. The update is rolling out across the board and is designed to help people get better research results directly inside the note-taking workspace.
Launched in 2023, NotebookLM lets you interact with notes and sources using AI. With the Gemini 3.5 upgrade, Google says the assistant will provide higher-quality answers and fewer mistakes, making it more useful for students, researchers, and knowledge workers who rely on concise, trustworthy summaries from their materials.
One of the biggest practical improvements is that you can now start a research project simply by asking NotebookLM questions about a topic: the app will use Google Search to find and suggest relevant sources instead of requiring you to import documents or videos first. That streamlines discovery and speeds up the early stages of research.
The update also adds a cloud-based computing capability to handle heavier analysis and larger datasets more smoothly. Combined with better source-finding and improved answer quality, these features make NotebookLM a more powerful assistant for organizing, exploring, and synthesizing knowledge.
Overall, the upgrade pushes NotebookLM further toward being a practical research companion—helping more people start projects faster, find credible sources, and get clearer answers from their notes.
