Podcurate

Podcurate makes it easier to manage your podcast listening queue and curate custom feeds from external sources. This service aims to solve a problem: you came across a podcast episode you want to listen to, but you're not subscribed to that podcast and don't intend to listen to more than one episode. With Podcurate you can instantly add that episode to a custom feed from your browser, and it will automatically be added to your podcasting app. Create a feed with our browser extension and add episodes to your feed with one click. Sign-up to unlock the ability to create multiple feeds, edit feeds, share feeds with friends, favourite episodes, copy episodes from feed to feed, and much more.
