Noisely is supposedly an "intelligent podcast player". According to Download Squad, if you enter words that describe what you want to listen to, Noisely will find the right podcast for you. "Noisely works solely online in your browser and searches through their database, spitting out results based on matching keywords, and the date the actual podcast took place."
For example, just type "NEJM", and the podcast starts automatically. Noisely worked well with popular feeds like NPR and BBC but did not find JAMA podcast in my test today.
