Check whether your podcast ad read ran
Give Claude the episode link and the brand. Podcast Sponsor Finder downloads the episode, listens to it and says whether an ad for that brand was heard, with the minute it starts and the words spoken.
3 free episodes a month. Nothing to install, no API key.
What to ask
Was an ad for <brand> heard in this episode? Give me the words and the minute it starts: <episode link>If you only have the show's name, ask Claude to list its newest episodes with their links first.
Two answers from one episode
Episode: “Who Will Emerge as the New Face of the GOP?”, Plain English with Derek Thompson (2026-11-10).
Asked for ServiceNow · heard · starts at 46:59
“This episode is brought to you by Service Now. Look, I have my dream job. I get to explain complicated ideas to folks who have better things to do than read white papers.”
Asked for Chewy · not heard
“No ad for Chewy was heard … in the copy downloaded”
The answer then listed the ads that were heard in the episode.
The tool returned the brand as “ServiceNow” and wrote “Service Now” in the words of the ad. It is a model's hearing, and spellings can differ like this.
What “not heard” means, and what it doesn't
It hears the copy of each episode that its server downloads, in the United States. Many podcasts insert ads at download time, and those differ by listener, place and day, so another listener may hear other ads. An ad the host reads can be inserted too, so the kind of ad doesn't show whether every listener hears it.
We measured this on one episode. Downloaded on the same day, the copy fetched from a server in the United States contained six ads, and the copy fetched from Türkiye contained one.
- “Not heard” is not proof the ad didn't run. It may have been served to other listeners, or the model may have missed it.
- “Heard” is not proof every listener got it. It was in one copy.
Use it for two things: to find the minute to listen to, and to check reads that are baked into the episode file, which are in every download. It is not a substitute for an ad-verification vendor's delivery reports.
What it costs
One episode per check. A check is free when the episode was already in one of your lookups in the last 30 days. 3 episodes a month are free; Pro is $19 a month or $149 a year for 100 episodes a month (fair use). See pricing, or the docs for supported links and limits.
Questions
- How do I check whether my podcast ad ran?
- With Podcast Sponsor Finder added to Claude, give it the episode's link and your brand's name. It says whether an ad for the brand was heard, with the minute it starts and the words spoken.
- It says my ad was not heard. Did the show skip it?
- Not necessarily. It hears the copy of each episode that its server downloads, in the United States. Many podcasts insert ads at download time, and those differ by listener, place and day, so another listener may hear other ads. An ad the host reads can be inserted too, so the kind of ad doesn't show whether every listener hears it. The model may also have missed it. Ask the show for its delivery report before you raise it as a missed ad.
- Does “heard” mean every listener got the ad?
- No. It means the ad was in the one copy our server downloaded, from the United States, on that day. An inserted ad, including one the host reads, can be served to some listeners and not to others.
- What does a check cost?
- One episode per check, or none when the episode was already in one of your lookups in the last 30 days. 3 episodes a month are free.
