Castmagic

Turns a recorded podcast episode, call, or voice memo into dozens of written assets — show notes, blog drafts, social posts, and a newsletter — instead of video clips.

What it does

Castmagic takes something you’ve already recorded — a podcast episode, a customer call, a rambling voice memo — and turns it into structured written content: show notes with chapters, a blog draft, a set of social posts, and a newsletter blurb, all generated from the same transcript. Unlike video-clipping tools, it doesn’t produce short-form video; its job is turning spoken content into the written assets a creator or marketing team would otherwise write from scratch after every recording.

Ideal users

  • Podcasters who want show notes, chapters, and a blog post generated automatically from each episode
  • People who think out loud better than they type — turning a recorded conversation or voice memo into structured written content
  • Teams that record calls, interviews, or webinars and need a batch of written social posts and a newsletter draft from each one
  • Anyone whose bottleneck is writing follow-up content from something already recorded, not creating video clips

Who should avoid it

  • You need short vertical video clips, not written content — OpusClip or Munch Studio are built for that
  • Your source content is text (a blog post or document), not audio or video — Castmagic starts from a recording
  • You process very high volumes of audio on a tight budget — hours are metered by plan and overages add up

Key features

  • Automatic transcript generation in 60+ languages
  • Speaker diarization that separates host from guest with high accuracy, so quotes are attributed correctly
  • AI-generated show notes with chapters and key takeaways
  • One-click blog post generation from episode content
  • Template library for show notes, YouTube descriptions, LinkedIn posts, and other social formats
  • Audiogram generation and public sharing links
  • AI strategist / chat interface ("Magic Chat") for querying and remixing generated content

Pros

  • Produces a wide range of written assets — not just a transcript — from a single recording
  • Strong speaker diarization means quotes and takeaways are attributed to the right person automatically
  • Unlimited AI outputs and re-generations on every paid plan, so you're not metered per piece of content
  • Template library covers most common repurposing formats out of the box
  • API access included from the Starter plan up, useful for teams wiring it into their own pipeline

Cons

  • No confirmed free-forever tier — entry pricing starts at a paid monthly plan
  • Transcription hours are capped per plan, and overage costs aren't published
  • Doesn't produce video clips — pair with a video-first tool if short-form video is also a goal
  • Higher tiers (Team, Business & Scale) get expensive quickly for high-volume podcast networks

Pricing

Paid — $19/month (Hobby, billed annually)

Castmagic has no permanently free tier; entry pricing starts at Hobby ($19/month billed annually, or $39/month billed monthly, 30 transcribed hours), confirmed directly on castmagic.io/pricing.

Typical workflows

  • A podcaster uploads the raw audio from a new episode; Castmagic transcribes it, generates chaptered show notes and key takeaways, then drafts a blog post and a set of social captions from the same recording.
  • A team records a customer interview or internal call and uses Castmagic to produce a written summary, quote-based social posts, and a newsletter blurb without anyone manually re-listening to the recording.

Integrations

  • Zoom, Google Drive, and RSS feed import
  • Zapier
  • YouTube, TikTok, and Instagram (import)
  • API access (Starter plan and above)

Frequently asked questions

Does Castmagic create video clips like OpusClip does?

No — Castmagic works from the audio/text side of a recording and outputs written assets (show notes, blog posts, social copy, a newsletter), not video clips. Pair it with a video-first tool like OpusClip if short-form video is also a goal.

How accurate is the transcription and speaker attribution?

Castmagic is specifically noted for strong speaker diarization, correctly separating host from guest so that generated quotes and takeaways are attributed to the right person, which matters for show notes and social posts pulled directly from the conversation.

Is there a free plan?

No permanent free tier — Castmagic's pricing page starts at the paid Hobby plan. It does offer a 7-day free trial with no credit card required, which is the best way to test the product before subscribing.

How is pricing structured?

Plans are metered primarily by transcribed hours per month, not by number of outputs — every plan includes unlimited AI-generated outputs and re-generations from whatever hours you've used, so the real constraint is how much audio you process, not how many pieces of content you generate from it.
