Like the sibling comment, I rolled my own (local Parakeet + Gemini), but this uses the same approach and is actively developed: https://github.com/podly-pure-podcasts/podly_pure_podcasts

I like the approach it acts as a kind of RSS proxy which cleans up the original feed. Also just offloading the task to the LLM API is really something. Thanks for sharing and i hope your SaaS works out for you!

Would love to look at it, but GitHub gives 504.
