I don't know if you already know the Sponsor Block add-on ( https://sponsor.ajay.app/ ) that allows users to tag the parts of a youtube video that contain sponsored content but also the self-promotional parts, the long useless introductions or the beginning and end credits. Then other users who watch these videos and who also have Sponsor Block will see their video player automatically skip the tagged parts of the video and this is sometimes a huge time saver ^^

Before I knew about this add-on, I had thought about something similar for podcasts, but it doesn't exist as far as I know. I had proposed a way out on AntennaPod's Github ( https://github.com/AntennaPod/AntennaPod/issues/3382 ) at the time but the developers told me that it was difficult and that they did not plan to create their own web service.

Being a big consumer of podcasts for years and seeing the progressive arrival of ads I thought it might be a good idea to build a similar service.
