What they are
Castmagic
Castmagic ingests podcast episodes, video recordings, and audio files, then uses AI to produce transcripts, show notes, social posts, newsletters, and more from a single upload. Podcasters, course creators, and video producers use it to repurpose long-form content without manual editing. It covers the full repurposing workflow in one place, though the output still benefits from a human edit before publishing.
Sonix
Sonix is an automated transcription service that converts audio and video files into text using AI, then lets you search, edit, and export transcripts in multiple formats. Journalists, podcasters, researchers, and video producers use it to speed up post-production workflows. Transcription accuracy is solid for clear audio but drops noticeably with heavy accents or poor recording conditions. There is no free tier, so you pay from the first minute.
