What is Castmagic?

Castmagic is an AI content platform that takes long recordings, such as podcast episodes, webinars, interviews and meetings, and turns them into written and visual assets. You upload a file or paste a link, Castmagic transcribes it, and then it drafts show notes, summaries, blog articles, newsletters, social posts, quotes and short clips from that single source.

The product is aimed at podcasters, video creators, B2B marketing teams, internal content teams and agencies that manage several brands. Its core idea is repurposing: one recording becomes many pieces of content without someone rewriting everything by hand.

Key Features of Castmagic

Transcription in 60+ languages

Uploads are transcribed with speaker labels and timestamps, and Castmagic supports more than 60 languages. Files of up to 10GB can be uploaded, and recordings can also be imported from links on a long list of platforms.

AI content outputs and custom prompts

From a transcript you can generate show notes, long-form articles, newsletters, LinkedIn posts, YouTube descriptions and more. Outputs can be edited and regenerated without limits, and you can save your own prompts or use community prompts.

Brand voice training

You can tune tone (casual versus formal, concise versus detailed), add preferred and banned vocabulary, and build reusable templates so drafts sound closer to your own style.

Studio: clips, audiograms and images

The Studio side cuts captioned vertical clips, creates audiograms and image carousels, and includes AI image generation, so a single episode can also feed short-form video and visual social posts.

Media library, semantic search and MCP

Every recording sits in a searchable library. Semantic search finds moments by meaning rather than exact words, and a Castmagic MCP connector lets Claude search and cite your transcripts.

Workspaces and integrations

Agencies can separate clients into workspaces with folders, roles, comments and approval steps. Imports and automations work with Zoom, Google Drive, Zapier, RSS feeds and YouTube, TikTok and Instagram links, and a podcast autopilot can draft content for each new episode in a feed.

Castmagic Pricing

Castmagic sells three self-serve plans plus a sales-led tier. The figures below are the annual-billing prices displayed on the pricing page, where annual billing is advertised as saving 30% compared with paying monthly. All three self-serve plans include unlimited AI content, regenerations and clips; the differences are transcription hours, storage, seats and API access. Extra transcription hours can be purchased at any time.

Prices checked on October 27, 2026; check the official pricing page for current plans.

Who Should Use Castmagic?

  • Podcast hosts who want show notes, timestamps and social posts ready soon after an episode is published.
  • Video creators and streamers who repurpose long videos into clips, scripts and newsletters.
  • B2B marketing teams that run webinars and customer interviews and need blog and email content from them.
  • Agencies and podcast networks managing several brands, which benefit from separate workspaces and approval flows.
  • Teams that want to search across a back catalog of recordings for quotes and stories.

Is Castmagic Worth It?

Castmagic is a focused tool for anyone whose content starts life as audio or video. The breadth of output types, unlimited regenerations on every plan and the brand voice settings make it practical for a regular publishing schedule, and the workspace features suit agencies more than most transcription tools do.

The limits to weigh are the transcription hour caps, which are a library total rather than a monthly reset, the absence of a free plan on the pricing page, and API access only from the Starter plan. AI drafts still need a human edit for accuracy and voice. If you produce long-form recordings every week and spend hours turning them into written content, Castmagic is worth a trial; occasional creators may find the Hobby plan's 30 hours enough, or may not need a dedicated tool at all.
