About
PodcastGPT is the AI analyst at the heart of CastFox, a comprehensive podcast intelligence platform built for professionals who work with podcast data at scale. Using natural language, users can ask PodcastGPT anything — from "top tech podcasts in the US" to comparing specific shows side-by-side — and get instant, data-backed answers pulled from a database of 5M+ podcasts and 114M+ transcribed episodes. The platform follows a four-step workflow: Discover shows using AI-powered filters or conversational search; Analyze audience demographics, chart rankings, episode sentiment, and social presence; Organize findings into curated lists and dashboards; and Pitch with AI-generated personalized outreach using 2M+ verified contacts. CastFox aggregates data from Spotify, Apple Podcasts, YouTube, and Amazon, providing a unified view of podcast performance across 100+ countries. Features include smart content search (searching what episodes actually say, not just titles), side-by-side show comparisons, social channel analysis, comment sentiment, platform distribution metrics, and a developer API for custom integrations. The platform serves a wide range of users: advertisers and agencies finding the right shows for brand campaigns, entrepreneurs and startups building awareness through strategic appearances, PR teams scaling podcast outreach, brands measuring sponsorship ROI, researchers analyzing trends, and individuals looking to land podcast guest spots. A free tier is available with no credit card required.
