Summary
- NotebookLM now has a 1 million token context window, increasing the ability to process large documents and improving cohesion across multiple interactions.
- Users can customize the template for specific roles, such as academic advisor or marketing strategist, by adjusting the behavior to “Custom.”
- Conversation history is automatically saved, allowing you to resume discussions at any time, with privacy maintained on shared notebooks.
Google announced significant updates to NotebookLM, with an 8x increase in context window (now 1 million tokens) and six times larger conversation memory. Improvements to the AI platform, based on the Gemini model, are now available to all users.
Previously, the context window was limited to 125 thousand tokens, while the new limit allows you to process large documents, such as entire books or transcripts of long meetings in a single conversation. The expanded memory also allows for greater cohesion even after multiple interactions.
New objective system personalizes responses
Another improvement to NotebookLM is that any user can configure the model to take on specific roles, such as academic advisor, marketing strategist, or game master. Just click on the configuration icon in the chat and set the desired behavior under “Custom”.


Examples include “Rigorously challenge my assumptions,” “Provide an immediate action plan,” or “Analyze the material from three distinct perspectives: academic, creative, and critical.” Customization adapts to varied needs and helps you deliver a response that meets your specific objective with the material you uploaded to the template.
Technical improvements and performance


NotebookLM now explores documents from different angles, synthesizing information into more accurate answers. This is especially useful for notebooks with large volumes of data sources, such as financial reports or academic research, where more nuanced contextual analysis helps deliver more reliable answers.
The updates led to a 50% increase in the quality perceived by users, according to Google.
Conversation history is saved
Perhaps one of the most important new features is the conversation history, which will be automatically saved, so that the user can resume discussions at any time. Until then, each session was temporary, requiring users to repeat the context or save specific responses as notes.
This feature will be gradually made available over the next few weeks. On shared notebooks, the chat remains private, visible only to the person who created it.
