Turn your podcasts and videos into marketing content

Castmagic is an AI-powered content automation platform that transforms your audio and video recordings into multiple publish-ready content formats. Whether you're a podcaster, content creator, coach, or marketing professional, Castmagic helps you maximize the value of every recording. The platform processes your audio and video files to automatically generate accurate transcriptions with timestamps and speaker identification. But Castmagic goes far beyond simple transcription: the tool generates show notes, summaries, social media posts, newsletters, blog articles, key quotes, chapters, and subtitles. The Magic Chat interface lets you interact with your content like ChatGPT, but specifically trained on your recordings. You can create custom prompts to adapt the tone and style to your brand, and synthesize multiple recordings to create complete articles or training courses. Castmagic supports over 60 languages and integrates directly with YouTube, Vimeo, Google Drive, Zoom, and RSS feeds. The platform also offers team collaboration tools, allowing you to manage projects, schedule posts, and work together on the same content. With over 75,000 active creators and 10 million minutes processed, Castmagic has established itself as a reference for audio/video content repurposing.
