A really cool feature coming to NotebookLM soon is the ability to let your users interact with the podcast. It's in BETA right now. There's a YouTube video showing how it works.

It seems users will be able to ask questions to the man and woman presenting the podcast (based on the information you've uploaded) (Limited to 50 sources) and they will interrupt their dialogue to discuss your thoughts.
