The shared AI backbone
Every CastFox AI feature is built on the same three layers: an OpenAI-powered natural-language interpreter (GPT-4o-mini) that distills free-text intent into precise search keywords, a chart-intersect query engine that joins Apple Podcasts daily rankings with our 5M-show podcast index, and a stop-word-aware tokenizer that matches topics against title, description, host, and category fields.
What differs between features is the interface and the ranking weights. Podcast Finder optimizes for consumer delight with mood presets. MediaList Builder exposes every filter for researchers. Guest Finder layers a Pitch Score formula on top of the same index. One backend, purpose-built surfaces.
That architecture is why new features ship fast at CastFox — the infrastructure compounds. Every podcast you find through one tool is discoverable through all of them.
