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.

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 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.
