My product https://reasonote.com allows you to generate podcasts as well, and it's had this feature for a few weeks.

Improvements over NotebookLM:

(1) You can start with just a subject, and you don't need a full document to begin (though you can do that too![1])

(2) The podcast generates much faster

(3) The podcasts are interactive -- you can ask the hosts to change direction mid podcast, and they will do so.

(4) (Coming soon) You'll be able to make a Spotify-style Queue of Podcast topics, which you can add to as you encounter new ideas.

The primary tradeoff is that the voices / personalities are somewhat less engaging than NotebookLM at this time, though this will be dramatically improved over the coming months.

This is all in addition to the core value proposition, which is roughly "AI Generated Duolingo for Any Subject".

It's early days, but I'd love for you all to check it out and give me feedback :)

[1] Documents are currently heavily length-limited but this will be improved shortly

Have you tried doing what they do, where you generate the script, then run it through again and ask it to add the pauses and personality to the script?

That's coming soon, yes! I'm learning about how to emotionally prompt the different voice APIs right now. Eleven labs has some interesting writing on the subject in their prompting guide.

I'm also playing with other voice models -- built an awesome "voice actor simulator" with OpenAI Realtime Voice -- but it's expensive. Considering asking users to pass in an OpenAI API key for advanced voice? Or maybe just passing the per-token cost along to the user in their subscription.
