I expect these things to comoditize through open source.

You guys are talking about something I've been thinking heavily on for a bit now.
First, I'm a HUGE fan of notebookLM... and there IS an open source version of it! Podcastfy.ai!
I have actually thought deeply about how we could bring podcastfy to PPQ.AI but we haven't been able to get to it yet. I even went so far as to have a conversation with a friend about it and he gave me some thoughts on deploying it:
If either of you are interested, if I created a bounty for you to deploy this for me it would be amazing. If you are interested, let's set a call at some point because there is a lot more to explain.
Unfortunately, I've already got my hands full with nostr:nprofile1qqspp9hkhc9y6lcwesklfmfvs6plzsl0eq0whglvumd2m5hu5ax8anqprpmhxue69uhkummnw3ezucmgv95k6cfwd9hxvme0qyt8wumn8ghj7mmjv9hxwetn09hxxtn5v43kstcpr3mhxue69uhkymmnw3ezummjv9hxwetn09hxxtn5v43kstcsa3stq, but nostr:nprofile1qqszyfx6zltkhwrl73s3amerjck6qnc4f2dmueqn2h7tv3ywxkwjyzsppemhxue69uhkummn9ekx7mp0jrp9c6 might be interested.
