Google is developing a system prompt feature for its NotebookLM product. This functionality will introduce a dedicated settings section for each notebook, enabling users to customize prompt messages and style guidelines. The customized prompts will offer a variety of options, potentially allowing users to define specific roles, which could further influence the assignment of guest roles in podcast audio summaries, thereby introducing new capabilities to the product.

Style guidelines are intended to shape the writing style of chat outputs and may also affect audio summaries. Users can modify the tone, vocabulary, and other elements of the chat content based on the style guide to ensure that the generated content adheres to specific stylistic standards.

Furthermore, Google is continuously enhancing its chatbot solutions, allowing users to create chatbots tailored to specific notebooks. These bots will have access to the notebook's knowledge base. Recent updates indicate that users will be able to view the created chatbots on the homepage alongside their notebooks and will have access to filtering options to easily view only the chatbots.

Although there have been no significant updates to this feature yet, it has been revealed that Google is working on a new version. With NotebookLM recently announcing its availability to enterprise users, the chatbot feature is expected to garner considerable attention. These chatbots can be shared with other users, enabling team members to access the same resources and prompts, thereby enhancing collaborative efficiency.

Google's series of updates aim to improve the functionality and user experience of the NotebookLM product, offering users a more flexible and efficient notebook usage experience.
