Something like this would be interesting to me, many podcasts I listen to are not here or on some of the other links shared by others. Sometimes I can jump around and find roughly the right space for the segment to share but often I can't. It doesn't feel helpful to share a 2 hour podcast for a minute of discussion.
Currently I'm using Algolia but others have pointed out some alternatives I'll have to check out. Would love to hear any feedback/ideas you have from your project!
