Does Omnflow handle podcasts like Castmagic?
Yes — paste a podcast or video transcript, or a YouTube URL, and Omnflow pulls out the strongest ideas and rewrites them as LinkedIn posts, threads, captions, scripts and newsletter sections. If you mainly need audio transcription and show notes, Castmagic is purpose-built for that.
