PodcastGPT: Ask Anything About 5M+ Podcasts — And Get Real Data Back
Most podcast search tools give you the same thing: a title, a description, and maybe a category tag. You type in a keyword, scroll through dozens of results, and still have no idea which show actually reaches your target audience.
That is the problem we built PodcastGPT to solve. It is an AI-powered podcast research assistant that goes far beyond metadata. Ask it a question in plain English — about any podcast, any market, any genre — and it pulls from real audience demographics, daily chart rankings, listener reviews, social media performance, YouTube analytics, and episode-level data across 5 million shows and 110 million episodes.
No filters to configure. No spreadsheets to export. No 45-minute research sessions. Just ask what you need and get a data-backed answer in seconds.
Why PodcastGPT Is Different From Every Other Podcast Tool
There are plenty of podcast databases out there. Podchaser, Listen Notes, Rephonic, Pod Engine — they all let you search podcasts by keywords and categories. Some even offer audience estimates.
Here is what they do not give you: the ability to ask a complex, multi-layered question and get back a single, complete answer with real data.
PodcastGPT is not a search bar. It is an AI agent with full access to CastFox's entire data infrastructure. When you ask it a question, it decides which tools to use — podcast search, chart rankings, audience demographics, review analysis, social media stats, YouTube channel data, RSS feed parsing — and combines everything into one coherent response.
What PodcastGPT Has Access To (That Other Tools Do Not)
- Audience demographics — age, gender, income, interests, geography. Not estimates. Real listener composition data.
- Daily chart rankings — Apple Podcasts charts across 100+ countries, updated every day. See where a show ranks in the US, France, UK, Germany, Brazil, and everywhere else.
- Listener reviews and sentiment — thousands of Apple Podcasts reviews analyzed for patterns, complaints, praise, and audience feedback.
- Social media performance — follower counts, engagement rates, and social presence across platforms.
- YouTube analytics — subscriber counts, view stats, and growth data for podcasters with video channels.
- Episode-level data — publishing frequency, episode length patterns, guest appearances, and content themes.
- Growth metrics — which shows are climbing the charts fastest, which are declining, and where the momentum is.
This is not metadata. This is the full picture. And you get it all through a single conversation.
15 Things You Can Ask PodcastGPT Right Now
The best way to understand what PodcastGPT can do is to see the kinds of questions it handles. Here are real use cases across different scenarios — from advertisers building media plans to PR teams booking guests to podcasters researching their competition.
For Podcast Advertisers
"Find me business podcasts in the US with a female audience over 60% and at least 10K listeners"
PodcastGPT searches the database, filters by audience demographics (not just category tags), and returns shows that actually match your target buyer persona. Perfect for brands selling products to women professionals.
"Which health and wellness podcasts have the fastest chart growth in the last 90 days?"
Instead of paying premium CPMs for established shows, find rising podcasts before their ad rates go up. PodcastGPT pulls growth trajectory data from daily chart rankings.
"Compare the audience demographics of Huberman Lab vs The Diary of a CEO"
Side-by-side comparison of listener age, gender, income, geography, and interests. Know exactly where your ad dollars will land before you sign the insertion order.
For PR and Guest Booking
"Find podcasts about fintech that accept guests and have published an episode in the last 30 days"
PR teams spend hours manually checking if podcasts are still active and if they feature guests. PodcastGPT checks publishing recency and episode formats automatically.
"What are the top 10 marketing podcasts in the UK ranked by listener reviews?"
Useful for guest pitching — shows with more reviews tend to have more engaged audiences, making them better targets for thought leadership appearances.
For Podcasters Researching Competition
"How does my podcast compare to the top 5 shows in the Technology category in the US?"
Understand where you stand in your category. PodcastGPT pulls chart positions, estimated listeners, review counts, and publishing cadence for your competitive set.
"What topics are trending in the true crime podcast space right now?"
Analyzes episode titles, descriptions, and chart movements across the true crime category to identify emerging content trends you can capitalize on.
"Which comedy podcasts chart in both the US and Australia?"
Cross-market analysis in seconds. PodcastGPT checks chart data across multiple countries simultaneously — something that would take hours to do manually on Apple Podcasts.
For Market Research and Media Buyers
"Give me a breakdown of the podcast landscape in France — top genres, biggest shows, and market trends"
Get an instant market overview for any country. PodcastGPT aggregates chart data, genre distribution, and top shows across all 100+ countries CastFox tracks.
"Find Spanish-language podcasts about personal finance with audiences in Mexico and the US"
Multilingual, multi-market research that would normally require a media agency. PodcastGPT handles language filters, country charts, and audience overlap analysis.
"What are the top 5 tech podcasts in the US?"
Quick-fire category rankings pulled straight from daily chart data. No guesswork, no opinions — just real listener behavior data.
For List Building and Tracking
"Build me a list of 20 business podcasts with audiences earning over K annually"
PodcastGPT uses audience income demographics to filter shows — a level of targeting that keyword-based search tools simply cannot offer.
"Which podcasts in my category dropped out of the top 50 charts this month?"
Track competitive movements. Identify shows losing momentum (potential ad rate negotiation opportunities) and shows gaining traction (potential partnership targets).
"Tell me about The Diary of a CEO — full breakdown"
Deep dive into any single podcast: chart history across all countries, audience composition, review sentiment, social media presence, YouTube stats, episode frequency, and growth trajectory.
"Find podcasts similar to How I Built This that chart in Canada"
Audience overlap and content similarity analysis combined with geographic chart filtering. Find lookalike shows in specific markets for targeted campaign expansion.
Use PodcastGPT to Build Podcast Lists in Minutes
One of the most powerful use cases for PodcastGPT is list building. Whether you are a media buyer assembling a campaign plan, a PR team building an outreach list, or a podcaster identifying cross-promotion partners — PodcastGPT turns hours of manual research into a single conversation.
Traditional podcast databases force you to set filters, scroll through results, click into individual show pages, and manually compile spreadsheets. With PodcastGPT, you describe what you are looking for in plain language, and it builds the list for you — complete with audience data, chart rankings, and relevance scores.
Some list-building prompts to try:
- "Build a list of 15 parenting podcasts with audiences aged 25-40 in the US"
- "Find 10 podcasts about sustainability that have YouTube channels with 50K+ subscribers"
- "List all podcasts that rank in both the Business and Technology categories in the UK"
- "Give me 20 health podcasts sorted by review count"
Each result links directly to the podcast's CastFox analytics page where you can explore deeper data, track chart movements, and make informed decisions. Explore the Best Podcasts rankings to see the kind of data available for every show.
Track Podcast Performance Over Time
PodcastGPT is not just a one-time search tool. Use it to monitor how podcasts perform over time — chart position changes, new episode drops, review volume trends, and audience shifts.
For advertisers, this means you can track the shows you are advertising on (or considering) and catch performance changes early. A podcast that drops 30 spots in the charts might signal declining listener interest. A show that suddenly jumps into the top 10 could be an underpriced advertising opportunity.
For podcasters, tracking your competitors helps you understand what content drives chart performance and where gaps exist in your category. Ask PodcastGPT questions like:
- "How has Lex Fridman's chart position changed over the last 6 months?"
- "Which new podcasts entered the top 50 in Business this quarter?"
- "Compare my show's review growth vs the category average"
You can also use the Charts page to visually browse rankings by country and genre, or set up CastFox Alerts to get notified when specific podcasts hit chart milestones.
Built for Podcast Advertisers Who Need Real Audience Data
If you are buying podcast ads, you already know the biggest challenge: finding shows where your target customer actually listens. Category tags and download numbers tell you almost nothing about who the listeners are, what they buy, or whether they match your ideal customer profile.
PodcastGPT solves this by giving you access to the same audience intelligence that media agencies charge thousands for — audience demographics, listener interests, geographic distribution, income levels, and engagement patterns. All through a conversation.
This is why PodcastGPT is different from tools like Podchaser or Rephonic. Those tools give you metadata and basic audience estimates. PodcastGPT gives you a complete audience picture powered by CastFox's data infrastructure — the same data that feeds our Charts, Best Podcasts rankings, and Category pages.

How PodcastGPT Works Under the Hood
PodcastGPT is not a simple chatbot with a podcast database bolted on. It is an AI agent built on top of CastFox's full data platform. When you ask a question, the AI decides which combination of tools to use:
- search_podcasts — full-text search across 5M+ podcasts with smart filtering
- get_rankings — daily chart data from Apple Podcasts across 100+ countries
- get_episodes — episode-level analytics including publish dates, lengths, and content analysis
- analyze_rss — deep RSS feed parsing for publishing patterns and content trends
- get_podcast_charts — category and country-specific chart rankings
- get_reviews — Apple Podcasts review analysis with sentiment scoring
- get_socials — social media presence and engagement data
- get_youtube_stats — YouTube channel analytics for video podcasters
The AI combines data from multiple tools in a single response. Ask "compare Joe Rogan vs Lex Fridman" and it will pull charts, demographics, reviews, social stats, and YouTube data for both shows — then present a structured comparison you can actually use.
You can see which tools were used at the bottom of every response, so you always know where the data came from.
