Google’s NotebookLM gains new features for customised AI conversations

Google has enhanced its NotebookLM assistant by introducing a feature that lets users customise AI-generated audio conversations. This update shifts the platform from providing generalised audio summaries to facilitating more focused discussions based on users’ preferences. The tool allows users to guide AI dialogue using specific content, adding precision to audio overviews.

Since launching last month, NotebookLM’s audio overviews have become popular among users looking to digest complex information quickly. With these features, long documents and videos can be summarised into conversational audio snippets. NotebookLM has seen significant traction, with traffic surging by 371% in September, drawing over 3 million monthly visits.

The new ‘Guide the Conversation’ option enables users to give detailed instructions for targeted discussions, such as focusing on niche topics or adjusting the expertise level. Google also introduced a ‘Customise’ button to refine audio overviews further before the AI generates them. This ensures conversations prioritise essential content and align with user intentions.

Google assures users that custom instructions won’t be used to train its AI models, reflecting its commitment to privacy. Alongside the new tools, a ‘Background Listening’ feature allows users to play audio while working within NotebookLM. Additionally, the company has launched a business pilot program, offering select organisations access to advanced features and training.
