No, Soundiiz is not handling podcasts yet. So none of your podcasts will be listed on Soundiiz (that means when you are retrieving playlists on Soundiiz (eg. from Spotify), podcasts will not be listed).
Why ? Because many podcasts are only available on one platform. While Soundiiz is doing a matching process, we will not be able to match them if they are only existing in one place. Comparing to "tracks" which are mostly available in all music streaming services catalogs.
Also, not so many music platforms are providing APIs for "podcasts" (being able to search and add them to favorites or playlists). That will probably change in the future and we are keeping an eye on this.
Maybe one day ? Maybe yes, even if it's not hope to us, if something is changing about podcasts, we will add this too to Soundiiz ! And same for videos content, a great alternative / addition to audio only.
