What they are
Captions
Captions is a mobile-first AI video editor aimed at creators who produce talking-head content for social media. It auto-generates captions, removes filler words, corrects eye contact, and can clone your voice for overdubs. The app targets solo creators who want a post-production shortcut, though its desktop feature set is still catching up to its mobile counterpart.
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.
