Swell AI
Swell AI ingests podcast episodes, YouTube videos, or audio files and generates transcripts, show notes, blog posts, social clips, and newsletters from a single upload. It targets podcasters and video creators who want to repurpose content without hiring a writer. The output quality is solid for first drafts but typically needs editing before publishing. A free tier exists with limited monthly credits.
Castmagic
Castmagic ingests podcast episodes, video recordings, and audio files, then uses AI to produce transcripts, show notes, social posts, newsletters, and more from a single upload. Podcasters, course creators, and video producers use it to repurpose long-form content without manual editing. It covers the full repurposing workflow in one place, though the output still benefits from a human edit before publishing.
