What happens when I exceed my monthly transcript limit?

Your transcript generation will pause for the month. You can either wait for your credits to reset next month or upgrade to a higher plan for more credits.

Can I migrate my existing podcast to Castos?

Yes. Castos offers free, one-click migrations from other podcast hosts. They handle the technical transfer of your feed and episode archive.

How does the YouTube Republishing feature technically handle audio-to-video conversion?

The system automatically generates a static waveform or branded visualizer video from your audio file and publishes it directly to your connected YouTube channel.

Does the Seriously Simple Podcasting WordPress plugin sync all episode data?

Yes, it's a two-way sync. Episode creation, edits, and scheduling done in WordPress push to Castos, and changes made in the Castos dashboard pull back into WordPress.

How does Castos Ads dynamic insertion work on older episodes?

You can create a Campaign and set it to insert an ad into your entire back catalog. The ad is dynamically stitched into the audio stream at the moment of download, requiring no re-editing of original files.

Is there a limit to the number of private subscribers I can have?

Yes, limits are tied to your plan (Essentials: 100, Growth: 250, Pro: 500). You can purchase additional batches of 500 subscribers as an add-on if you need more than your plan includes.
