CastFox Podcast Topic Search is the fastest way to find podcasts about a specific subject. Type any topic in plain English and the AI returns the best-matching shows ranked by current Apple Podcasts chart position, audience size, and topical fit. Searches across 5 million podcasts spanning 100+ countries and 30+ languages. Free to use; no account required to search.
Type a topic the way you would describe it to a friend. "Long-form interviews with bootstrapped founders." "Sustainable fashion podcasts hosted by women." The AI interprets your intent and translates it into search filters across the CastFox database.
Searches across 5M+ podcasts indexed from Apple Podcasts, Spotify, indie hosts, and every major directory. You see the show that fits your topic, not the one a single platform decided to promote.
Narrow to specific countries (100+), categories (20+), or languages (30+). Useful for finding regional shows in foreign markets or English-language shows about non-English topics.
Results are ordered by current Apple Podcasts chart rank in the country you select, not by an opaque "AI score." You see what people are actually listening to, not what the AI thinks you should listen to.
Every search can be saved to your account. Revisit it anytime to see new podcasts that match your topic of interest, including newly published shows and freshly charting ones.
You describe a topic in plain English — like "true crime with female hosts" or "sustainable fashion interviews" — and the AI distills it into a precise search keyword. CastFox then matches that keyword against 5M+ podcasts, filtering by your selected country, category, language, and episode history, and ranks results by chart position and popularity.

Anything — health, fintech, parenting, true crime, motorsports, obscure hobbies. The AI handles broad or narrow queries equally well, from "AI podcasts" to "podcasts about late-stage sleep-wake disorders for clinicians".
It searches across podcast titles, descriptions, host names, category metadata, and recent episode titles. Topic intent is matched against the full text corpus, so a query about a niche subject surfaces shows even if the topic is not in the show name.
Yes. Save any topic search to your account and re-run it later. Newly published podcasts and freshly charting shows are included in the next run.
