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.
Runway
Runway is a browser-based AI video platform used by filmmakers, social media creators, and marketing teams to generate, edit, and transform video with text and image prompts. Its Gen-4 Alpha model produces short video clips from text or images, while traditional editing tools sit alongside AI features in one workspace. Output quality impresses at short durations, but longer or complex scenes still require significant iteration.
