Particle Unveils Radar: AI Platform Indexing 130,000 Podcasts for Web & Agent Search

AI startup Particle has officially launched Radar, a podcast intelligence and indexing platform designed to make audio content fully searchable across the web. Radar continuously transcribes and semantically analyzes over 130,000 podcast feeds, transforming unstructured spoken conversations into structured, queryable data.

Beyond web search interfaces, Radar provides API endpoints specifically formatted for autonomous AI agents, enabling digital assistants to query expert podcast discussions for real-time news, interviews, and deep-dive technical insights. The platform addresses a major blind spot in traditional web crawling.

Media analysts expect audio intelligence engines like Radar to open new distribution and monetization avenues for podcasters as conversational search queries increasingly replace traditional text indexes.
