The web is searchable. Podcasts should be too. Today we're introducing Radar, the podcast search engine. Podcasts contain some of the most thoughtful, candid, and timely conversations happening right now. But that knowledge is difficult to discover. Radar lets you search and spot trends in over 130,000 actively transcribed podcasts, with ~20,000 new episodes added daily. Millions of hours and billions of lines, all fully searchable by entity, keyword, or semantic search. Radar is powered by Particle’s Podcast Intelligence API, which allows your agents to search across the world’s podcasts via API and MCP.

Podcast search finds what was said. Speaker Expertise now tells you who said it. Each speaker on Particle now carries a profile: occupation, standing in the field, seniority, whether they still practice. We have 2,800+ occupations and fields across 160,000+ podcasts. Hear what nuclear engineers say about small modular reactors. Or what practicing cardiologists say about GLP-1s. Tell your agent: “Search Particle for what practicing cardiologists say about GLP-1 drugs.”
