Castmagic is an AI-powered content platform that transforms recorded audio and video into transcripts and a range of derived content. After a file is uploaded or imported, Castmagic transcribes it with speaker diarization and then automatically generates summaries, show notes, timestamps, titles, social media posts, newsletters, and other assets from the same recording. The platform integrates with sources including YouTube, Apple Podcasts, Google Drive, and Zoom, so recorded meetings and interviews can flow directly into a workspace for processing alongside podcast episodes. Castmagic includes semantic search across a media library, brand-voice customization, reusable templates, and commenting and approval workflows aimed at teams and agencies that manage content for multiple brands. While its marketing centers on podcasters and creators, the transcription, speaker labeling, and summary features make it applicable to meeting and interview recordings as well. It is intended for content teams, marketing agencies, podcasters, coaches, and sales organizations that want to convert recorded conversations into transcripts and repurposed written content rather than only a raw transcript. Pricing varies by plan. Check the official website for current pricing.
