What is CastFox
CastFox is a podcast intelligence and outreach platform that transforms how marketers, PR professionals, and advertisers discover and analyze podcasts. It indexes over 5 million podcasts and 114 million episode transcriptions, enabling users to search by what hosts and guests actually discuss — not just titles or descriptions — using AI-powered semantic search and a conversational tool called PodcastGPT. Each podcast profile includes six analytics tabs covering listener estimates, Apple Podcasts chart rankings across 100+ countries, aggregated reviews, episode archives, YouTube channel metrics, and an AI-generated web presence report.
Beyond discovery, CastFox provides a database of 2M+ verified contacts for podcast hosts, producers, and booking managers, along with built-in outreach tools for generating personalized pitches, managing automated follow-ups, and tracking responses in a unified inbox. Users can build curated podcast lists, compare shows side-by-side, export data as CSV, and monitor brand or keyword mentions across the podcast ecosystem with instant email alerts.
The platform is designed as an end-to-end workflow — from initial discovery through outreach and reply management — positioning itself against research-only tools by connecting data directly to action. Searching and listening are free; podcast tracking and advanced features operate on a credit system, with 20 free credits provided on signup and additional credits purchasable as needed.

What makes CastFox unique
Unlike research-only tools such as Rephonic or Listen Notes, CastFox positions itself as an end-to-end podcast intelligence and outreach platform — covering the full workflow from AI-powered content search (across 114M+ episode transcriptions) through analytics, verified contact sourcing, pitch generation, follow-up automation, and reply tracking, all within a single product. Its transcript-based search means it can surface podcasts that discuss a topic without mentioning it in their title or description, a capability CastFox explicitly contrasts against metadata-only competitors like Listen Notes.
