Barry provided a great example. If you listen to his AI & Life's Big Decisions overview, you will think this is a video that was found with humans talking. But it is synthetic (totally made up). Gemini, in an instant, read Barry's sources and created a new video about them with realistic human voices.
I submitted a prompt to Goggle's AI search to provide a brief explanation. Below is that explanation. Also, the following is a video - with a real human (I think, but am not sure) - that provides an overview of Notebook:

The video and audio overviews created in Google Notebook are fully AI-generated on the fly. The hosts are entirely synthetic, and there are no real humans involved in the conversation.
The system operates in mere minutes using the following process:
- The Process: You upload your own source documents, PDFs, or links. A multimodal AI parses the data and writes an outline, followed by a detailed, conversational script. It then synthesizes the audio, adding realistic conversational fillers (like "ums" and "ahs") to sound like a natural human podcast.
- Cinematic Video: In addition to audio-only podcasts, Google Notebook also features visual overviews. These are generated by advanced AI models that act as "creative directors," crafting visual aids, diagrams, and fluid animations synchronized with the synthetic audio narration.
AI responses may include mistakes.
