Next.js, Node.js, Express, TypeScript, PostgreSQL, Redis, OpenAI
CastFox.net's answer:
CastFox is the only podcast intelligence platform that searches actual episode content using AI transcription across 114M+ episodes , not just titles and descriptions. It also uniquely combines YouTube channel analytics, AI-generated Web Presence reports, and an in-app AI Pitch Wizard into a single platform. No competitor offers all of these together.
CastFox.net's answer:
CastFox gives you more data for free than competitors charge hundreds per month for. All search, analytics, contacts, and PodcastGPT are free forever. Competitors like Rephonic charge $99-$299/month for basic analytics, and Podchaser Pro costs $2,500-$5,000/year. CastFox also offers features no competitor has: AI content search, YouTube analytics linked to podcast profiles, and batch pitching with AI-generated emails.
CastFox.net's answer:
Media buyers and ad agencies finding podcasts to advertise on, PR agencies booking guest appearances for clients, brand marketers monitoring industry conversations across podcasts, authors and speakers looking for shows to promote their work, and podcast creators analyzing competition and growth opportunities.
CastFox.net's answer:
CastFox was built out of frustration with how hard it was to find the right podcasts for marketing campaigns. Every existing tool only searched titles and categories, missing the vast majority of relevant shows. We built an AI engine that searches what hosts actually say across 114M+ episodes, then added the analytics, contacts, and outreach tools needed to go from discovery to signed deal in one platform.
