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.

Udio

Udio is an AI music generation tool that produces complete songs, including vocals and instrumentation, from a text description. It is used by content creators, podcasters, indie game developers, and musicians looking for quick backing tracks or original compositions. The output quality is impressive for AI-generated audio, though the tool gives you limited fine-grained control over individual stems or arrangement details.
