What they are
Wordtune
Wordtune, from AI21 Labs, is an AI rewriting tool that offers multiple alternatives per sentence with tone control, surfacing sharper, more formal, or more casual versions instantly. It is favoured by ESL writers and professionals who want to sound more natural. It deliberately skips grammar checking and chat, so it covers less ground than all-in-one rivals.
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.
