I'd be happy to rebrand it if there's interest. The main issue is that generating an episode is around $3 roughly (~$1 on GPT4 APU, ~$2 on text-to-speech). So doing a daily episode in multiple languages might be a bit costly.
But if there's enough interest, I might be happy to fund it to get it going for a bit and see how it ends.
Either way, I'd be happy to fund a few weeks of a French version right now!
Let me see if I can get a French episode generated for you today or tomorrow and if you like it, I'm happy to send some more your way :)
What is your level of French?
On that note, another suggestion: Offering a mobile-friendly readable transcript to go along with the audio. (RFI does this.) Reading along with the audio is my preferred way to "listen" to French audiobooks.
Also, presenting the transcript in a readable form is another way to gate content behind a log in and/or upsell. Of course, yeah, would rather it all be free, but your costs are real!
