What Castos does well

Strong private podcasting, with password-protected feeds and private subscribers for courses, memberships, and internal company shows.
Unlimited podcasts, episodes, and downloads on every plan, with no upload or audience caps.
Built-in monetization, including dynamic ad management and listener donations, with YouTube republishing on higher plans.

What PodcastAI does well

The content production is the core product, included in one flat price. One upload produces the transcript, chapters, video clips, social posts, and a website automatically.
Video clips and standalone social posts are produced as part of every run. Castos does not generate short-form clips, and its AI titles, show notes, and social posts are a paid add-on.
It hosts and distributes your show as well, so the content and the publishing happen in the same place.
A dedicated SEO-optimized website is built automatically for each episode, so your show has a home that search engines can find.
PodcastAI hosts your podcast and publishes episodes to major podcast directories including Apple Podcasts and Spotify.

Choose Castos if…

Your podcast lives on a WordPress site and you want to publish from your dashboard.
You run private or membership podcasts and need gated feeds and private subscribers.
You want unlimited shows, episodes, and downloads with built-in monetization.
You want a hosting platform with content tools you can add as you grow.

Choose PodcastAI if…

You want the content from each episode, clips, social posts, chapters, produced automatically and included in one flat price.
You want short-form video clips, which Castos does not generate.
You want content included rather than metered by credits or sold as an add-on.
You want the work after recording handled for you, not a hosting platform to operate.

The bottom line

There are two categories of podcast software. Podcast infrastructure platforms help you host, distribute, and manage your podcast. Podcast workflow platforms automate everything that happens after recording. Castos is a hosting platform built around WordPress integration and private podcasting. PodcastAI is an automated podcast workflow platform that produces the content from each episode and also hosts and publishes the show.

Castos is a podcast hosting platform. PodcastAI is an automated podcast workflow platform. Both host and distribute your show, and they overlap on content tools, but they lead with different things, and that is the cleanest way to understand the difference.

Castos has been around since 2015 and built its name on two things. The first is WordPress: it owns the Seriously Simple Podcasting plugin, one of the most popular podcast plugins for WordPress, so you can publish episodes straight from your site's dashboard. The second is private podcasting, with gated feeds and private subscribers for courses, memberships, and internal company shows. Every plan includes unlimited podcasts, episodes, and downloads, and it adds dynamic ad management, listener donations, AI transcripts, and a customizable website. For WordPress creators and anyone running private or membership podcasts, Castos is one of the best fits available.

Hosting is included with PodcastAI, but the platform is built around automating everything that happens after recording. You upload once, and it generates the transcript, chapters, video clips, social posts, and a website, then hosts and publishes the show. The content production is the core of the product, included in one flat price. On Castos, transcripts are metered by monthly credits, the AI assistant that writes titles, show notes, and social posts is a separate add-on, and short-form video clips are not part of the toolkit.

So the distinction is what each platform leads with. Castos is a hosting platform built around WordPress and private podcasting, with content tools you add on or meter by credits. PodcastAI centers on content production, the transcript, clips, social posts, and website, produced automatically from one upload. If WordPress integration or private podcasting is your priority, Castos is an excellent choice. If you want the work that happens after recording handled automatically, from transcripts and clips to social posts, your website, and publishing, PodcastAI was built for that.

Frequently asked questions

Is PodcastAI a Castos alternative?

They overlap a lot but lead with different things. Castos is a hosting platform built around WordPress integration and private podcasting, with content tools available alongside hosting. PodcastAI hosts and distributes your show too, but its core is automating the content from each episode, the transcript, clips, social posts, and a website, included in one flat price. If WordPress integration or private podcasting is your priority, Castos is built for that. If you want the content produced for you automatically, that is where PodcastAI fits.

What does Castos do that PodcastAI does not?

Castos leads with WordPress, private podcasting, and monetization. It owns the Seriously Simple Podcasting plugin, so you can publish straight from your WordPress dashboard, it offers gated private feeds with private subscribers for courses and memberships, and it includes dynamic ad management and listener donations. PodcastAI does not integrate with WordPress, run private feeds, or run a monetization program. It is built to produce the content and publish the episode.

Do both generate transcripts and social posts?

Yes, with a difference in how. Castos includes AI transcripts metered by monthly credits, and its AI assistant for titles, show notes, and social posts is a $10 per month add-on. PodcastAI produces the transcript, social posts, and chapters automatically on every run, included in the flat price, and it also generates video clips, which Castos does not.

How is PodcastAI priced compared to Castos?

Castos is tiered from $19 to $99 per month, with no free plan but a 14-day trial, and its AI content assistant is a $10 per month add-on. PodcastAI is a flat $99 per month with a 14-day free trial and the content included. At the top tier the base prices match, but the content tools are bundled differently, included with PodcastAI versus metered or added on with Castos.

Should I use Castos and PodcastAI together?

Usually not, since PodcastAI already hosts and produces the content. If you specifically need WordPress publishing or private membership feeds, Castos handles those well, while PodcastAI handles producing and publishing a public show. For most public podcasts, PodcastAI covers the hosting and the content in one place.
