What Castline saves
Use Castline for uploaded audio files, direct audio file URLs, pasted text, and article URLs. Pro text-to-speech turns readable content into podcast-ready episodes.
Personal podcast feed
Create a personal podcast feed for saved audio and articles.
Castline turns files, direct audio URLs, text, and article URLs into private RSS feeds that work in podcast apps.
How delivery works
Each personal podcast feed uses token-protected RSS and protected media URLs, so saved content can be played from podcast apps without a public podcast listing.
Who it fits
Founders, researchers, operators, creators, and professionals can keep briefings, calls, interviews, articles, and reference audio in one listen-later feed.
Personal podcast feed FAQ
Is a personal podcast feed the same as public podcast hosting?
No. Castline focuses on private listen-later delivery, not publishing a public show or distributing to podcast directories.
Can I listen in my existing podcast app?
Yes. Castline produces standard RSS feed URLs that can be opened in podcast apps that support custom feeds.
