Castmagic

What is Castmagic?

Castmagic is a web app that turns one audio or video recording into a transcript plus show notes, newsletters, social posts and short clips. It is built for people who publish long recordings and need material for many channels from each one.

The process starts with an upload or a link. Castmagic transcribes the file with speaker labels and timestamps, usually within minutes, and then runs a set of content tools over the transcript. The company says a single recording can supply more than 100 content assets, and users can edit each draft, ask questions of the recording or cut clips in the built-in Studio.

Castmagic says more than 100,000 podcasters and creators use the service. Named customers on its homepage include HubSpot, Yahoo Sports, Wistia and Maxwell Leadership, with Yahoo Sports quoted as repurposing hundreds of hours a month. Recent additions include semantic search across a media library and a Claude connector built on the Model Context Protocol.

Key Features

Transcription and the 130-plus content tools do most of the work in Castmagic, since every other output is generated from that one timestamped transcript.

• Transcription: Castmagic produces speaker-labelled, timestamped transcripts in more than 60 languages. Files in MP3, WAV, M4A or MP4 format up to 1GB can be uploaded, and processing typically finishes within minutes of upload.
• Content tools: A catalogue of more than 130 tools drafts show notes, blog articles, newsletters, LinkedIn posts, quotes, action items and email sequences. Users pick the outputs they need, so a weekly episode can fill several channels at once.
• Brand voice: Brand voice training and a vocabulary list help drafts follow a house style and spell names correctly. Custom templates can be saved and reused, which keeps a recurring show’s notes in the same format each week.
• Studio clips: The Studio builds captioned video clips, audiograms and image carousels from highlights in the recording. Hobby and higher plans include unlimited clips and audiograms, so short-form output is not metered separately.
• Magic Chat: Users can question a recording in plain language to find quotes, facts or timestamps. This is handy for long interviews, where scrolling a two-hour transcript to find one remark would take far longer.
• Team workspaces: Separate spaces keep brands or clients apart, with Admin, Editor and Viewer roles. Comments, tasks and approval steps let an editor sign off content before anything is published.

Pros

Volume per upload is why podcasters adopt Castmagic: one episode can produce transcripts, notes, posts and clips in a single pass instead of hours of manual writing.

• Many assets per upload: One recording can supply a week of newsletters, posts and clips. Castmagic’s own figures claim a 97% cut in content creation time, which shows the scale of savings the company reports.
• Wide import options: Links from YouTube, Spotify, Apple Podcasts, TikTok, Instagram Reels, X, Vimeo, Twitch, Loom, Wistia and RSS import directly. Teams rarely need to download and re-upload a file before processing.
• Broad language reach: Transcription and writing cover more than 60 languages, including Hindi, Japanese and Mandarin. International shows can produce content in the language they recorded in without a separate translation tool.
• Developer access: Starter and higher plans include a REST API, and Zapier links Castmagic to thousands of other apps. Agencies can automate the path from new episode to finished draft without manual uploads.
• Agency-friendly structure: Hobby allows three spaces and Team allows up to 25. Each client brand can keep its own templates, voice and library, which reduces the risk of mixing material between accounts.

Cons

Hour caps are the main constraint with Castmagic, because transcription allowances of 30 to 400 hours a year push heavy publishers towards the dearer tiers.

• Transcription hour caps: Hobby includes 30 hours and Starter 100 hours. A daily show or a team processing many webinars can use that allowance quickly, so check your yearly recording volume before choosing a plan.
• Annual billing pressure: The headline prices assume yearly billing, and monthly plans cost about 30% more according to the pricing page. Buyers who want flexibility pay a noticeable premium for it.
• Steep upper tiers: Business and Scale plans start at $699 and run to $999 a month. The jump from the $139 Team plan is large for growing agencies that only slightly exceed 400 hours.
• Thin security detail: The pages we read listed no security certifications, such as SOC 2, or data residency options. Companies handling confidential meetings should ask for documentation before uploading sensitive recordings.
• Drafts still need editing: Generated posts and articles follow the transcript closely, so weak or noisy recordings lead to weaker drafts. One directory notes that good audio quality matters, and editors should plan time to polish outputs.

Who is Using Castmagic?

Podcasters are Castmagic’s largest group, alongside marketing teams, agencies and creators who turn webinars, interviews and talks into written content.

• Podcasters: Hosts use it to write show notes, timestamps and newsletters for each episode. Many also cut audiograms to promote new releases on social media.
• Content marketers: In-house teams at firms such as HubSpot turn webinars and interviews into blogs. They also draft LinkedIn posts and email sequences from the same recording.
• Agencies: Production studios keep each client in a separate space with its own brand voice. Approval workflows let account managers check drafts before delivery.
• Coaches and educators: Experts and teachers reuse talks, lectures and courses as articles and carousels. Searchable libraries help them find past material when planning new content.

Pricing

Castmagic starts at $19 a month on yearly billing after a limited free trial (official prices, October 2026).

Castmagic’s own llms.txt quotes $21 a month, one directory still lists a $29 starting price, and a 2026 review mentions a $790 Business plan.

Disclaimer: Castmagic has reshaped its plans several times, so confirm the current figures at checkout.

What Makes Castmagic Unique?

Castmagic leaves the recording untouched and focuses on everything written about it, from the transcript and show notes to the newsletter and social posts.

Editing tools such as Descript centre on cutting audio and video, while clip tools such as Opus Clip focus on short vertical video. Castmagic combines a large catalogue of writing tools with team approvals, multi-brand spaces and a Claude connector that can search a whole media library, which suits agencies more than solo editors.

Compatibilities and Integrations

Castmagic runs in any modern browser and connects to recording, storage and automation tools through imports, Zapier and a REST API.

• Platform: Browser-based web app for Windows, macOS and Linux.
• Imports: YouTube, Spotify, Apple Podcasts, Zoom, Google Drive, Loom, Wistia and RSS.
• Files: MP3, WAV, M4A and MP4 uploads up to 1GB each.
• Automation: Zapier, a REST API on Starter and above, and a Claude MCP connector.

Castmagic Tutorials

Processing a first episode in Castmagic takes about five steps and a few minutes of waiting.

1. Start the trial and create a space for your show or brand.
2. Upload an audio or video file, or paste a link from YouTube or a podcast feed.
3. Check the speaker names and correct any misheard terms in the transcript.
4. Choose outputs such as show notes, a newsletter or LinkedIn posts.
5. Edit the drafts, then build clips or carousels in the Studio.
6. Copy, export or send the content onward through Zapier.

How We Rated It

Castmagic earns 4.1 out of 5, driven by its breadth of content tools, while sparse security documentation and costly upper tiers hold the score back.

Summary

Castmagic suits podcasters, marketers and agencies who publish long recordings and need written content from each one. Its 130-plus tools, wide import options and team spaces make it one of the broader repurposing platforms we have reviewed. The main drawback is that transcription hour caps push regular publishers towards dearer tiers, and security documentation is thin. Before paying, run two real episodes through the trial to judge how much editing the drafts still need.
