NotebookLM, Google's experimental AI -first notebook and research assistant, has gone viral for its Audio Overview feature, which transforms a user's material into a podcast. The feature just got an upgrade to fine-tune the experience, and I put it to the test.

Google's product lead for the AI podcast tool, which now has millions of users, told BI that customizing instructions was the most requested feature.

Google’s NotebookLM now lets you customize its podcast-like Audio Overviews. Before you generate a discussion using the note-taking app, you can give your AI hosts instructions about what topic you’d like them to focus on, or even tailor their discussions for different audiences.
