X Rolls Out Video Reactions So You Can Reply With Your Face

X has introduced a new “React with Video” reply feature for iOS users, allowing people to respond to posts with a selfie video overlay or split-screen recording — bringing a TikTok-style interaction format natively into the platform for the first time.

“Commentary is one of the most important pillars of X. And sometimes the best way to share your thoughts is with video.” — Nikita Bier, Head of Product, X

How the feature works

The option appears directly within the post reply menu. When selected, it opens a recording window that activates the front-facing camera and lets users film their reaction in real time. The resulting clip can be displayed as an overlay on top of the original post or formatted as a split-screen, with the source post visible alongside the reaction video for added context.

Why this matters for X’s engagement strategy

The move comes as video activity on X continues to grow, and it underscores just how reply-driven the platform already is. According to figures cited by former CEO Linda Yaccarino, 300 million of the 500 million daily posts on X are quote posts or reposts — meaning the vast majority of activity is reactive rather than original. A native video reply tool could deepen that engagement further,
