X has refreshed its video upload and posting process once again, with this latest update providing a more focused layout, and editable captions, which can be refined using the app’s Grok-powered artificial intelligence tools.

According to X developer Allegra Jacchia, the platform’s new video editor is cleaner, more intuitive and much easier to use.

The main focus of the update is the improved captioning process, which lets creators manually edit captions in the composer, or ask Grok to correct them. It also allows Grok to translate captions into another language.
