NotebookLM
NotebookLM, renamed Gemini Notebook in July 2026, turns your sources into an Audio Overview: two preset hosts discussing your documents. You can pick Shorter, Default, or Longer, but you cannot edit the script or change the voices, and since September 2, 2026 usage is metered by a compute budget. It has no RSS feed, so publishing to Spotify or Apple means moving the audio or sources into a podcast host.
