I have had very good results using Spectropic [1], a hosted Whisper Diarization API service as a platform. I found it cheap and way easier and faster than setting up and using whisper-diarization on my M1. Audiogest [2] is a web service built upon Spectropic, I have not yet used it.
disclaimer : I am not affiliated in any way, just a happy customer! I had some nice mail exchanges after bug reports with the (I believe solo-)developer behind these tools.
