It was made with
NotebookLM, a Google product that you can add sources of all kinds of formats (including links to Kiwifarms threads), and ask it to generate a podcast.
I had a play with it today, and I'm not sure if it follows all forum pages from a single link from a KF OP, but it did generate an interesting 20min podcast based on my limited tests.
The default voices sound just like a popular true crime podcast which I can't recall, you can choose how many hosts and their voices as well.
Kiwibros, we're not far off (or we are already there) where it's going to be near impossible to determine if the content we are consuming is by faggots or by AI.
This is the last bastion of the real internet. This forum. I stand with you, in human generated shitposting glory.
