Replaces hours of spreadsheet research with a single conversational query. Used by advertisers, agencies, PR teams, authors, and creators.

What this tool does

Plain-English audience targeting

Describe your audience or pitch target in natural language. "Mid-career female finance professionals in the US, 30-50, who listen to commute-friendly business podcasts." The AI translates that into structured filters across the full CastFox database.

Filter by 20+ data points

Country (100+), category (20+), language, listener-range bucket, episode count, last-publish window, host activity signal, content keywords. Combine any to narrow your list.

Ranked by audience-buyer fit

Lists are ranked by a composite score blending Apple chart position, audience size, recent guest pattern, and topical relevance. The top of every list is by definition the highest-leverage targets.

Export to CSV, Sheets, or your CRM

CSV export is free for the first 100 rows. Pro and Agency unlock larger exports plus direct push to HubSpot, Salesforce, Notion, and Google Sheets. Lists sync continuously, no manual re-uploads.

Verified host contacts on every row

Each podcast row includes verified host email, social profiles, and website URL. Pulled from the 4M+ CastFox contact database. Pro plans include 200 lookups per month; Agency is unlimited.

Save lists and re-run them automatically

Save any list and configure it to re-run weekly or monthly. New podcasts that match your criteria are added automatically. Useful for evergreen PR pipelines, ongoing advertiser shortlists, and quarterly media plan refreshes.

Who uses it

Podcast guests and PR teams

Build pitching lists by niche, country, and audience size. Pairs with the AI Pitch Email tool inside Guest Finder for end-to-end outreach.

Frequently asked questions

What is the MediaList Builder AI?

A natural-language tool that turns a description of your ideal audience or pitch target into a ranked, filterable podcast list. Type "100 active SaaS podcasts in the US that interview founders" and get back the matching list ranked by audience size, with the option to export to CSV, push to a CRM, or save for outreach.

How does it differ from a manual filter search?

Manual filtering requires you to know exactly which categories, countries, audience-size buckets, and activity windows to apply. MediaList Builder AI translates a plain-English description into all those filters automatically. Faster for non-technical users, more thorough for power users.

Can I export the list?

Yes. Free accounts can export up to 100 rows per export. Pro plans export 100 rows per export with unlimited exports. Agency plans are unlimited rows. Export formats include CSV, Google Sheets sync, and direct push to HubSpot, Salesforce, and Notion.

Does the list include host contact information?

Yes for Pro and above. Each row in the exported list includes the verified host email (where available), social profiles, and website. The CastFox contact database covers 4M+ verified podcast hosts and producers.

How many podcasts can I get in one list?

Free users get up to 50 podcasts per list. Pro is 200. Agency is unlimited. The AI ranks results by relevance and audience size, so even a 50-podcast list typically captures the top targets in your niche.

Can I save a list and re-run it on a schedule?
