Castmagic
Turn one podcast or video into dozens of assets — notes, clips, social posts, newsletters, blog outlines.
Castmagic ingests podcast or video audio and produces a full asset set: show notes, chapters, social posts, newsletter drafts, LinkedIn posts, blog outlines, and email subject lines. Custom prompts let agents extract specific content types per show. Frequently chained with Riverside, Descript, and Otter.ai in multi-agent podcast production workflows.
What it does
Drop in podcast or video audio, get back a publish-ready asset bundle. Notes, timestamps, social, newsletter, blog, even subject lines — all from a single source file.
What you get
- Show notes and chapters
- Multi-platform social posts
- Newsletter drafts
- LinkedIn posts
- Blog outlines and email subject lines
- Custom-prompt extraction per show
Why it matters
Podcasters spend more time on post-production than recording. Castmagic flips that ratio. The platform sits naturally inside the multi-agent podcast stack — Otter handles transcripts, Descript handles edits, Castmagic produces the repurposing pass.
