AI Content Disclosure
AI Content Disclosure lets you tell listeners and podcast apps whether AI plays a leading role in your podcast, such as an AI-generated voice or a script written entirely by AI.
You give one answer for your whole podcast, and you can give a different answer for any episode. Castos adds your answers to your RSS feed using the Podcasting 2.0 AI content tag.
What the AI content tag is
The AI content tag is part of the Podcasting 2.0 standard. It's a simple yes-or-no signal: true means the podcast or episode includes AI-generated content, and false means it doesn't. In your RSS feed it looks like this:
<podcast:txt purpose="ai-content">true</podcast:txt>
It can appear in two places:
- On your podcast, describing the show as a whole.
- On each episode, describing that episode.
Its purpose is transparency. Listeners increasingly want to know when a voice or script is AI-generated, and some platforms now ask creators to say so. The tag gives podcast apps a standard way to read your answer, so they can label or filter AI content without guessing.
When to choose Yes
Choose Yes when AI is the performer or the sole writer, for example:
- A synthetic or cloned voice reads the episode.
- An AI-generated host or narrator presents the show.
- AI wrote the entire script, even if a human read it.
Choose No when AI is only a production tool, for example:
- Editing, noise removal or mixing.
- Music or sound effects.
- Partial script contributions/research, transcripts, show notes, titles or chapters, including ones written with Castos AI tools.
If you're not sure, the Podcasting 2.0 standard points to Should I Disclose AI in My Podcast?, a short questionnaire that walks you through the decision.
Set your podcast's answer
- Open your podcast's Settings and choose Feed Details from the settings menu.
- Under AI Content Disclosure, choose Yes or No.
- Click Save.
Your answer applies to every episode that doesn't have its own answer, including episodes you publish later.
Set an episode's answer
Most episodes don't need their own answer. Set one only when an episode is different from the rest of your show, like an AI-narrated bonus episode on a show that's otherwise human-hosted.
- Create a new episode, or open an existing one.
- In Episode's Meta Details, find AI Content Disclosure, below Episode Type.
- Choose an option:
| Option | What it does |
|---|---|
| Use podcast setting | The episode follows your podcast's answer. The option shows that answer, for example Use podcast setting (No). If you change your podcast's answer later, the episode changes with it. |
| Yes | The episode always says it includes AI content, whatever your podcast's answer is. |
| No | The episode always says it doesn't include AI content, whatever your podcast's answer is. |
- Save the episode with Publish, Schedule, Update or Save Draft.
New and existing episodes start on Use podcast setting. Saving an episode for any other reason, like fixing a typo, doesn't change its answer. To make an episode follow your podcast again, choose Use podcast setting and save.
What appears in your RSS feed
Each episode in your feed gets the answer below:
| Your podcast's answer | Episode set to Use podcast setting | Episode set to Yes | Episode set to No |
|---|---|---|---|
| Not answered yet | No tag | Includes AI content | No AI content |
| Yes | Includes AI content | Includes AI content | No AI content |
| No | No AI content | Includes AI content | No AI content |
Your podcast as a whole gets your podcast-level answer, with one exception: if any episode in your feed is set to Yes, your podcast is also marked as including AI content. That way your feed never says the show has no AI content while one of its episodes does.
Which podcast apps show it
The AI content tag is relatively new, introduced in March 2026. As of October 2026, we're not aware of any major podcast app, including Apple Podcasts, Spotify, YouTube, Pocket Casts and Overcast, that shows listeners a label based on it yet. Several podcast hosts, Castos among them, now add the tag to their feeds so that apps can start using it. Answering now means your feed is ready when they do. However, direct
Apple Podcasts
Apple's content guidelines (section 1.11) say that creators who use AI to generate audio or video, "including synthetic voices, AI-generated hosts or on-screen personas, or AI-synthesized replicas of real individuals", must "prominently disclose this to audiences in the content and metadata for each episode and show."
Apple doesn't say which metadata to use. If this applies to your show, set your AI Content Disclosure answer, and also say so in your audio and in your show and episode descriptions.
FAQ
Do I have to answer?
Not right away. Until you answer, Castos leaves the tag out of your feed, apart from any episodes you've given their own answer. You'll be asked to choose Yes or No the next time you save Feed Details.
I use AI to clean up my audio or draft my show notes. Should I choose Yes?
No. Those are production tools. Choose Yes when AI is the voice or the sole writer of the episode.
I changed my podcast's answer, but one episode didn't change.
That episode has its own answer. Open it, set AI Content Disclosure to Use podcast setting, and save.
I'm moving my podcast to Castos from another host. Will my answers carry over?
Yes. If your current feed already includes the AI content tag, we copy your podcast's answer and each episode's answer when you import. If it doesn't, your podcast starts with no answer and its episodes start on Use podcast setting.
