Castmagic

Castmagic is an AI narration tool that turns one recording into transcripts, notes, clips and social posts. Castmagic converts podcasts, videos and meeting recordings into transcripts, show notes, clips, blog posts, newsletters and social copy, with multi-brand workspaces, brand voice controls and approval workflows for content teams and agencies.

Castmagic is a content operating system built around a single idea: a long recording already contains more material than most teams manage to publish. Upload an MP3, WAV, M4A or MP4 file (up to 1GB) or paste a link from YouTube, Spotify, Apple Podcasts, TikTok, Reels, X, Google Drive, Vimeo, Twitch, Loom or Wistia, and the platform transcribes the source with speaker labels and timestamps, then drafts downstream assets from that transcript. The output catalog is broad. Show notes, summaries, highlights, quotes, LinkedIn posts, blog articles, newsletters, meeting recaps, captioned vertical clips for social, image carousels and even YouTube scripts all come out of the same recording. The site describes more than 100 utilities in total, and a podcast autopilot mode can import and draft each new episode from a feed automatically. An audience chatbot can also be embedded on a site to answer questions from published episodes and capture leads. The product leans toward teams rather than solo hobbyists. Workspaces separate brands or clients, with folders, admin, editor and viewer roles, plus commenting, tasking and internal approval flows. Brand voice controls let users set tone (casual to formal, playful to serious, concise to detailed) and maintain vocabulary rules and reusable templates, so drafts land closer to house style on the first pass. Semantic search finds moments by meaning rather than keyword, which matters when someone remembers a story but not the episode it came from. The practical positioning is upstream of the editing suite. Castmagic does not replace a DAW for mixing or a full nonlinear editor for fine cutting; it sits between raw recordings and the publishing calendar, handling transcription, repurposing and multi-client workflow. Agencies, in-house media teams, podcast networks and B2B marketing groups are the stated audience, and named customers include HubSpot, Yahoo Sports, Wistia and Maxwell Leadership. A live MCP connection lets Claude search and cite the transcript library as context. Setup starts with an account, an import and a prompt, and the time to first draft is measured in minutes rather than hours.
