Castmagic

Castmagic takes a single podcast, webinar, or video recording and outputs a stack of marketing assets in the formats your team would otherwise spend hours writing by hand. Upload an audio or video file, and within minutes you get show notes, social posts, an email summary, a blog draft, YouTube chapters, quote cards, and short clip suggestions.

So the use case is repurposing, not creation. The recording already happened. The team's actual bottleneck is everything that comes after: writing the LinkedIn carousel, drafting the newsletter recap, picking the clip that goes on TikTok. Castmagic does the asset production layer that usually slows campaigns down.

Default outputs cover the formats most content teams actually ship:

• Episode show notes with chapter timestamps
• Social posts for LinkedIn, X, and Threads in matching voice
• Email or newsletter recaps
• Blog post drafts pulled from the transcript
• Quote cards with the strongest pull quotes
• Short clip suggestions with start and end times
• YouTube titles, descriptions, and chapter markers

Then there's the prompt library, where teams add their own custom output formats. Want a "guest pitch follow-up" template that pulls the three sharpest moments from the episode into an email? Save the prompt once and Castmagic runs it on every new recording from that point on.

Common workflows by role:

• Podcast producers ship a full asset pack within an hour of recording
• B2B content marketers turn webinars into multi-week content calendars
• Founders repurpose internal all-hands or fireside chats into thought-leadership posts
• Course creators slice long lessons into snackable social content
• Sales enablement teams turn customer calls (with consent) into case-study drafts

Plus the brand voice training lets teams feed in past content and have Castmagic match house style across outputs. Drafts come out closer to publish-ready and need less editing per asset.

A few specifics worth knowing:

• Transcription is included and handles speaker labels
• Custom prompts and templates apply across every recording in the library
• Web app and API are both available for higher-volume teams
• Output is editable in-app before exporting to whatever publishing tool the team uses

Of course, the bottleneck shifts from writing to recording. If a team isn't already producing podcasts, webinars, or long-form video, there isn't enough raw material for Castmagic to repurpose. The math only works when there's an interview, talk, or recorded session every week or two.

Paid subscription with tiers scaling by audio hours processed each month, custom templates, and team seats.

Best for content teams already producing podcasts, webinars, or long-form video who want every recording to fuel a week of derivative content. Not ideal for teams without a regular recording habit, where the input side of the pipeline is the real bottleneck.
