X is borrowing one of TikTok’s most familiar tools. The platform just launched React with Video, which lets you film a video response to any post instead of typing a quote.
Head of product Nikita Bier announced the feature on June 2. He framed it as a natural extension of how people already use the app for commentary.
Bier called commentary “one of the most important pillars of X,” and said video is sometimes the best way to share it. The mechanics are simple. You tap the repost button, then record a clip with green screen, split screen, or picture-in-picture. Your video then sits alongside the original post, so followers see your reaction and the source together.
How React with Video works
The format will look familiar to anyone who scrolls TikTok or Instagram Reels. Green screen drops the original post behind you, split screen stacks both videos, and picture-in-picture floats your camera over the post.
Reaction videos are not new to social media. TikTok built much of its culture on duets and stitches, and Instagram pushed Reels remixes for years. X is arriving late here, but it has the advantage of a feed already built around quick reactions and hot takes.
It is X’s answer to the reaction trend that drives a lot of short-form engagement elsewhere. Creators get a faster way to add commentary, while the original poster gets extra reach when their post fuels someone else’s clip.
Availability and the bigger play
For now, React with Video is iOS only. X says Android and the web client are coming soon, though the company has not committed to a firm date.
The timing fits X’s broader push to court creators and lean harder into video. Reaction clips keep people scrolling, and they give X another format to chase the short-video audience that TikTok and Reels built.
Whether it sticks depends on how many creators actually choose it over a normal quote post. For more platform news, see our look at how Twitch is reshaping streaming for the short-form phone era.
