Audio Overviews from the Workspace
The Kortex Workspace lets you generate, play and download Audio Overviews from Gemini Notebook (formerly NotebookLM) on every notebook row. You pick a style (Deep Dive, Brief, Critique or Debate), a depth, the sources and a language, and can add instructions.
Can Kortex generate and download Audio Overviews?
Yes. The Notebooks table in the Kortex Workspace has an Audio Overview column with Listen, Download, Add to podcast, Delete and Generate Audio. You pick a style, depth, sources and language. You can add instructions too. Downloads are .mp4 files. Google's own daily limits for Audio Overviews still apply.
What you get
-
One column for every notebook
Generate and play audio from the table. You do not need to open each notebook and find its Studio panel.
-
You set the brief
Choose Deep Dive, Brief, Critique or Debate. Choose a depth, the sources to use and a language. Then add instructions.
-
Download the file
Download audio overview saves the audio as an .mp4 file. It plays on a phone or in a video editor.
-
Send it on
Add to podcast sends an Audio Overview to a podcast feed. Delete audio overview removes one you do not want.
The Audio Overview column
In the Kortex Workspace, the Notebooks table has a column for audio. On each row you see Listen, Download audio overview, Add to podcast, Delete audio overview and Generate Audio. Audio Overviews are Gemini Notebook’s spoken summaries of a notebook’s sources. Kortex does not make the audio. It asks Gemini Notebook to make it, using your own Google session.
What can I set for an Audio Overview?
Generate Audio Overview asks for:
- a style: Deep Dive, Brief, Critique or Debate
- Depth: Short or Standard, and In-Depth for Deep Dive
- which Sources to use
- a language
- Instructions (Optional)
Choosing the sources matters most. A notebook with 40 sources makes one audio about everything. Pick five and it covers those five.
How do I download an Audio Overview?
Download audio overview saves an .mp4 file. Add to podcast sends one to a podcast feed, and Add selected to podcast sends several. Listen plays it in the Workspace.
Are there limits on Audio Overviews?
Gemini Notebook sets its own daily limits on Audio Overviews, and they apply here too. If generating stops, Google’s limit is the usual reason.
