A big thanks to Diane R for telling me about FluidDATA, available at https://fluiddata.com/ . It’s a search engine for podcast transcripts! From the About page: “FluidDATA podcast search engine allows you to search millions of podcast transcripts. Search all the best podcasts for keywords, topics, or people. View podcast statistics and trends in all the top podcasts. Add podcast transcript search to your podcast app or website with our advanced search API.” I sense an article in the future.
