Introducing Radar: The Podcast Search Engine
The web is searchable. Podcasts should be too.
Podcasts contain some of the most thoughtful, candid, and timely conversations happening anywhere. But most of that knowledge remains difficult to discover. Search engines can index an episode title or description, but they rarely understand what was actually said inside the audio.
That means an important idea, company, person, or emerging story can appear across dozens of podcasts without showing up in a traditional search.
Radar fixes that.
Powered by the Particle Podcast Intelligence API, Radar is a podcast search engine that makes spoken conversations searchable, discoverable, and most importantly, useful. Search across transcripts from 130,000+ podcasts, follow the topics and people that matter to you, identify emerging trends, and receive alerts when tracked entities are mentioned or certain guests appear.
All episodes available on Radar are fully transcribed, speaker-labeled, and rich with metadata. Try it for free today.
Search what was actually said, in near real time
Search by entity (company, person, topic, brand, product, etc.), exact keywords or phrases, or semantic search by meaning, to find the exact moments where it was discussed. With 20,000 episodes added every day, available within minutes after airing, Radar gives you unparalleled podcast coverage.
Entity search for Jeff Dean.
Browse 130,000+ podcasts and their episodes, with hundreds of podcasts added daily.
View the exact moments that matter, with transcripts that are segmented and speaker-labeled.
Spot trends across the conversation
A single mention can be interesting, but a sudden increase in mentions across many podcasts can be a signal. Radar provides a broader view of how a conversation is developing.
Get notified: Like Google Alerts for podcasts (but even better)
Radar Alerts let you monitor an entity mention or guest appearance automatically. Choose the person, company, or subject you want to follow, and Radar will notify you when it appears in a newly indexed episode.
Alerts can be delivered by Slack, Email, or Webhook, and can be configured to appear as-it-happens, or in a daily or weekly digest. Each alert surfaces the mention along with the episode it appeared in and transcript context, so you can quickly understand why the mention matters.
Everything you need to know about a podcast and its episodes
Browse the corpus of podcasts and their episodes to see all the metadata: hosts and guests, topics, listener ratings and reviews, and more. Business plan users can also access brand suitability, political bias analysis, chart rankings, audience size estimates, and sponsorship data.
Advertiser and Sponsorship Intelligence
Track advertisers and companies across podcasts, with Radar’s Ad Intelligence. Our Business Plan users can search sponsors and see detailed information about each placement, including transcripts.
