About CastFox
AI-powered podcast discovery with smart tracking. Search by content, build lists, and never miss episodes from your favorite shows.
The Problem We Solve
Finding podcasts you'll actually love shouldn't require hours of browsing through endless categories. Traditional podcast apps only let you search by title or browse generic categories like "business" or "comedy." You can't find shows discussing specific topics you care about, and you often miss new episodes from your favorites.
For marketers and advertisers, the challenge is even greater. You need to find podcasts reaching your target audience, but without audience data or competitive intelligence, you're making blind investments. Finding contact information and tracking opportunities across dozens of shows becomes a full-time job.
Our Mission
We're making podcast discovery smarter and more accessible for everyone. Whether you're a podcast fan who wants to find shows discussing your passions, or a marketer searching for the perfect audience, CastFox uses AI to help you discover what you're looking for.
Free to search. Free to listen. Track the shows you care about. CastFox transforms how people discover and track podcasts—from hours of random browsing to minutes of intelligent discovery.
