Particle's new Radar platform transcribes over 130,000 podcasts, turning spoken conversations into searchable intelligence for AI agents and hedge funds.

  • Radar indexes over 130,000 podcasts across 135 verticals.
  • The platform converts audio into searchable, structured data for AI agents via API and MCP.
  • High demand from hedge funds and AI search platforms like Exa.
  • Includes advanced features like ad tracking and topic-based alerts.

In a significant pivot for the AI landscape, Particle—a startup founded by former Twitter engineers—has launched Radar, a groundbreaking podcast intelligence engine. While the podcast industry has exploded in popularity, its content has remained largely 'dark' to traditional search engines and AI models. Radar changes this by transcribing and indexing the spoken word, making it discoverable for the first time.

Radar does more than just simple transcription; it possesses semantic intelligence. It can identify key quotes, highlights, and specific entities such as people, companies, and brands. Sara Beykpour, co-founder and CEO of Particle, noted that the platform has already seen massive traction from hedge funds, who are eager to integrate this previously invisible audio data into their algorithmic trading and research models.

Why This Matters

BozokMedia analysis shows that this development addresses a critical bottleneck in the growth of Artificial Intelligence. Most current AI agents are text-centric, meaning they are effectively 'blind' to the massive amount of information contained within audio formats. By providing an API and MCP (Model Context Protocol) layer, Radar is bridging the gap between audio content and machine intelligence.

"Agents are generally blind to audio; they can’t see it unless something or someone has transcribed it." — Sara Beykpour

The scale of Radar is immense. It currently indexes more than 130,000 podcasts, including the entire Apple Top 200 list. With 20,000 new episodes added to the index daily, the platform offers a real-time pulse on global conversations. Users can set customized alerts via Slack, email, or webhooks to be notified whenever specific guests or topics are mentioned.

Beyond simple search, Radar offers specialized tools for brand monitoring. It features a dedicated podcast ads search engine, allowing companies to track their advertising presence and trends across different shows. This provides a level of transparency in the podcasting economy that was previously unavailable.

The business model is designed for both individual users and enterprise-scale operations. While a web interface is available for $29 per month, the true power lies in its programmatic access through APIs, catering to data resellers and high-volume AI platforms like Exa.

Did You Know?: Radar is currently the largest transcribed podcast service in existence, processing thousands of hours of audio every single day.
