The Episode Aired. Now Someone Has to Write Everything Else.

Castmagic converts long-form audio and video recordings into transcripts, show notes, blog posts, newsletters, and social content automatically, replacing the post-production writing workflow that podcast teams currently outsource for $75 to $150 per episode. The recording is the input. The content library is the output.

Every episode a marketing team records creates a second problem: now someone has to write everything else. The show notes. The transcript. The SEO blog post that repurposes the best 800 words. The LinkedIn excerpt. The newsletter blurb. The tweet thread of five quotes worth saving. None of that exists in the audio file. It has to be produced, and producing it takes time that most teams either spend internally or pay a freelancer to absorb. Industry benchmarks put basic show notes from a professional at $75 to $150 per episode. Full content repurposing, meaning show notes plus a blog post plus social copy, runs closer to $300 to $500 per episode at agencies, or 3 to 4 hours of internal labor if handled by a content manager doing it manually.

For a B2B team publishing twice a month, that is either a freelance line item that compounds across a year, or a standing drain on someone's Tuesday afternoons. For a team publishing weekly, it is a budget category that tends to get quietly trimmed until the podcast itself gets trimmed.

Castmagic is a content platform that takes the recording and produces the writing. You upload an audio or video file, and the tool generates a transcript, a timestamped overview, show notes, a long-form article, a newsletter draft, LinkedIn posts, tweet threads, quote pulls, and more, all in a single pass. The platform supports 60+ languages, integrates with RSS feeds, YouTube, TikTok, Instagram, Zoom, and Google Drive for import, and lets teams build custom templates aligned to their brand voice so the outputs land in the right format every time.

The mechanics are straightforward. Castmagic transcribes the audio using what the company describes as best-in-class AI, then runs a series of content generation passes against the transcript. Each content type, show notes versus blog post versus LinkedIn post, can be generated with a single click from the same media file. The transcript is editable, and the generated drafts are editable, so the human role shifts from writing the thing to reviewing and refining it.

What the cost comparison looks like

Castmagic's pricing page shows three tiers billed annually: Hobby at $21 per month covering 5 hours of audio processing, Starter at $79 per month covering 20 hours, and Business at $790 per month covering 80 hours for larger teams and agencies. Each tier supports multiple seats and includes unlimited file uploads, unlimited content re-generations, audiogram creation, and integrations.

A B2B marketing team publishing two 45-minute episodes per month, roughly 1.5 hours of audio, sits comfortably on the Hobby plan at $21 per month. That replaces what would cost $150 to $300 monthly in freelance show notes alone, not counting blog posts or social copy. The Starter plan at $79 per month handles up to 20 hours of audio, which maps to roughly 25 to 30 standard podcast episodes per month, a volume most podcast networks or content agencies would recognize.

The comparison is sharpest for teams that are already running the manual workflow and paying for it. A content manager spending 3 hours per episode on post-production writing at a fully loaded cost of $50 to $75 per hour is generating $150 to $225 in labor cost per episode before benefits. Monthly, that is $300 to $450 for a bi-weekly show. Annually, it approaches $4,000 to $5,400, before factoring in the opportunity cost of what that content manager could be doing with those hours instead.

What changes in the workflow

The recording stays the same. The guest booking, the hosting, the audio editing, the final publish, none of that touches Castmagic. What the platform automates is specifically the translation layer from spoken content to written assets. Upload the finished episode, select the content types you want generated, review the outputs, adjust the brand voice where needed, and distribute. The company's own benchmark, cited on the homepage from users including Yahoo Sports, is 97% reduction in content creation time, which tracks if the baseline is someone writing long-form show notes and blog posts from scratch.

For agencies managing podcast production for multiple clients, the Business tier's multi-brand CMS and user permissions structure handles the workflow at scale. Each client gets their own space, voice templates, and content library. The human review layer stays, but the drafting layer disappears.

Who this is wrong for

Castmagic is built for teams that already have a podcast or video content program and a defined post-production writing need. If the podcast is just beginning, the tool generates outputs faster than a team can absorb and publish them, and the constraint shifts from production to distribution strategy. It is also a poor fit for content that requires deep editorial judgment in the writing itself, investigative pieces, opinion essays, content where the brand voice is highly idiosyncratic, because the outputs are close but human-supervised, not human-replaced. Any show where the written artifacts need to carry a distinct authorial perspective that goes beyond summarizing what was said will hit the limits of what transcription-to-draft can produce.

It is also worth noting that the tool does not solve the upstream problem. If the podcast episodes themselves lack substance, the repurposed assets will faithfully reflect that. Strong inputs produce strong outputs; weak recording sessions produce well-formatted weak show notes.

A closing observation

The podcast repurposing workflow has always been a quiet budget argument. Teams know the writing is valuable because it drives SEO, feeds email lists, and extends episode shelf life by months. They also know it is expensive and slow enough that it frequently gets deprioritized or abandoned. The interesting thing about a tool like Castmagic is that it doesn't change what the content is worth, it just changes what it costs to produce it. The teams that were already doing the repurposing will move faster. The teams that were skipping it will finally have a reason to stop.
