How would the right format for you look like? Specially be monologue?

It could be monologue or dialogue, but it should be less full of verbal "syntactic sugar" than NotebookLM podcasts. More to the point, more detail-oriented, can pronounce math.

Can pronounce math is the real showstopper for me. Last time I tried, NotebookLM would try to say the TeX out loud. Like underscore dollarsign...

It's been sometime I have been using an app called nouswise. I switched right after they added nblm notebooks in Gemini. I knew they cannot stand another app competing with their flagship. But anyway, it do have audio recap and it definitely have way less of "syntactic sugar". I haven't tried but because it's agentic you can ask it to generate a monologue for you. But I assume you should be in deep mode. I so far only used the side bar for this.

Readwise does this pretty well.

random idea -- driving while you drive?

1) you aren't able to listen to something safely while driving on the highway? 2) the cars pretty much drive themselves on the highway these days

Paper2Audio is great - and if you're looking to have more editorial control over the outputs, check out Jellypod. You can choose your hosts, publish it to a website/RSS feed, edit scripts, etc.

Jellypod is great as well!

Google Illuminate does this. I believe it was actually a precursor to Gemini Notebook. It uses a similar podcast generating model but tuned to keep things more technical and detailed.
