This site is merely a simple search engine for the spoken word of podcasts.
You can look up specific conversation bits, or sentences, or words, and get the episode and timecode in return.
All of the timecodes are clickable, and will start playing that specific episode from that specific timestamp. The indexing and transcription of the podcast might not be completely accurate, so you may have to rewind/forward a bit in the episode, if you are looking for a very specific sentence.
