One inbox for work audio
Use Castline for briefings, interviews, calls, research clips, and creator audio that you want to review away from your desk.
Listen-later audio inbox
A private audio inbox that follows you into your podcast app.
Save work audio, research clips, articles, and direct audio URLs into a podcast workflow instead of another browser queue.
Podcast app habit
Instead of creating another queue in a browser or file manager, Castline sends saved items to a private feed you can play in a podcast app.
Private by default
Your listen-later feed uses private RSS and token-protected media URLs. Public Square sharing stays separate from private feed access.
