Search engines can index an episode title or description, but they rarely understand what was actually said inside the audio. An important idea, company, person, or emerging story can appear across dozens of podcasts without showing up in a traditional search. Radar fixes that.
Search by company, person, topic, brand, or product to find the exact moments where it was discussed, across every episode.
Search exact keywords or phrases and land on the moment they were spoken, in a transcript that is segmented and speaker-labeled.
Search by meaning. Ask a question in plain English and find the moments that discuss it, whatever words were used.
A single mention can be interesting, but a sudden increase in mentions across many podcasts can be a signal. Trends measures every entity against its own history of mentions and shows you exactly what changed, when it changed, and why. Read how Trends works.
Total mentions alone would put inherently popular topics on top every day. By measuring each entity against its own baseline, Radar filters those out and surfaces the niche topic or breakout story with a surge in chatter.
A story that has been building for a week and a story that broke this morning both chart, while a story that has already peaked falls away. The breaking filter spots the newest.
Overall trends plus category charts for TV shows, movies, video games, guest appearances, and more, each with a podcast quote that tells the story and citations back to the exact moments.
