Particle is turning podcast conversations into a searchable data layer for AI agents and institutional research. Its new product, Radar, indexes more than 130,000 podcasts and adds roughly 20,000 episodes every day. Instead of asking users to find and play an entire episode, Radar transcribes the audio, identifies speakers, and tags mentions of people, companies, brands, products, and topics. It can return a specific quote or passage, along with a timestamped clip. The index includes Apple’s Top 200 podcasts across 135 categories, plus ratings, reviews, and episode advertising data. The clearest commercial use is ongoing monitoring. A user can set alerts for a guest discussing a topic, or narrow results to top podcasts, then receive updates by email, Slack, or webhooks. But the API is the strategic center. Particle says hedge funds are its highest-volume customers integrating directly with the API, while AI search platforms and data resellers also use the product. Agents can access Radar through the API or an MCP interface, turning spoken remarks into inputs for automated research and alerts. Consumer-facing plans start at 29 dollars per seat each month, or 399 dollars monthly for 20 seats; API pricing is customized. Particle plans to add YouTube videos and news clips, so the key question is whether Radar’s podcast index becomes the first layer of a broader searchable media system.

Story brief

3 key points

Particle is turning podcast archives into machine-readable market data with Radar, a product aimed at institutional research rather than playback. Its index covers 130,000+ shows, adds roughly 20,000 episodes daily, and returns speaker-labeled passages, entity metadata, quotes, and timestamped clips. The strategic wedge is programmatic access: hedge funds are the highest-volume API customers, while agents can query...

    Plans cost $29 per seat monthly or $399 monthly for 20 seats; API access has customized pricing.

AI agents built around web crawling have a new way to search the conversations they usually miss. Particle has introduced Radar, a podcast intelligence product that transcribes audio, extracts quotes and highlights, and exposes the resulting data through an API and MCP interface for businesses and agents.

The product is pitched less as a consumer podcast finder than as a searchable audio layer for institutional users. Particle says hedge funds are its highest-volume customers directly integrating with the API; AI search platforms and data resellers are also customers. Exa is identified as a Radar partner.

An index built for queries, not just playback

Radar indexes more than 130,000 podcasts and adds about 20,000 episodes each day. Particle says the collection includes Apple’s Top 200 podcasts across 135 categories. Each transcript can carry speaker labels and metadata for people, companies, brands, products and topics, so a search can return a specific passage rather than merely an episode title.

Monitoring turns mentions into a feed

The practical use case is ongoing monitoring. Users can receive customizable alerts for entities and topics through email, Slack or webhooks. Filters can narrow an alert to a guest discussing a topic or limit search to top podcasts, while timestamped clips let a user read and listen to the relevant remark.

What Radar puts into its searchable record

  • Transcripts with identified speakers, plus tracked people, companies, brands, products and topics.
  • Timestamped clips and extracted quotes or highlights for locating a relevant portion of an episode.
  • Listener ratings and reviews, episode advertising data, and a search tool for podcast advertising.

The API is the commercial center

Radar is available through a web interface, but Particle’s API and MCP interface are designed to let agents and other businesses retrieve its podcast intelligence programmatically. That design turns a spoken comment into a possible input for an automated search, alerting or research workflow, rather than a result someone must find by listening through an episode.

Particle lists Radar at $29 per month per seat and a $399-per-month business plan for 20 seats. API access uses customized pricing, putting the service’s most consequential use case outside a published rate card. The company plans to extend Radar beyond podcasts to YouTube videos and news clips, which would broaden the audio sources available through the same system.
