X has shipped an updated version of its native in-app video editor, and the headline addition is editable captions. The update was announced in early October 2026 by Allegra Jacchia, who leads X's Creators Product team (she joined from TikTok). She described the new editor as cleaner, more intuitive, and easier to use, and called editable captions one of the team's most-requested features.
The caption flow now works three ways. You can edit X's auto-generated captions by hand in the composer, ask Grok to correct them, or tell Grok exactly how you want them changed — including translating them into another language. That puts an AI editing pass directly in the posting flow, so a creator can fix a mis-transcribed word or ship a translated caption track without leaving the app or touching a separate tool.
The update builds on the native video editor and recorder X launched in July 2026, which introduced multilingual overlay captions you could style, plus green-screen recording with custom backgrounds from posts or your camera roll. The throughline is strategic: X has been pushing creators to make and post original video in-app rather than reposting clips from elsewhere, and keeping the edit-and-caption step inside X is how it keeps that content native to the platform. The refreshed editor has been shown in the iOS app; confirm current availability, platform, and the exact caption and Grok options on X's own channels before relying on them, since rollout details move.
Editing a caption inside X is a nice convenience for one X post, but the clip you just captioned almost certainly belongs on TikTok, Reels, Shorts, and LinkedIn too — and X's in-app captions do not travel. Re-upload the file elsewhere and the caption track, the crop, and the styling are gone; you are back to doing the work per platform by hand. That per-platform tax is exactly what [Kompozy](/) removes.
Drop a long talk or a single clip into Kompozy and it cuts [Clipped Shorts](/), transcribes with Whisper, and burns styled captions directly into the pixels — so the caption survives every re-upload instead of living inside one app's player. [Autopilot](/glossary/autopilot) reframes each cut to 9:16, 1:1, and 16:9, holds the look and wording to your [Persona Brief](/glossary/persona-brief), and publishes across the eight social platforms plus blog and email behind a per-post review — X included. And where X can only edit footage you already shot, Kompozy also generates net-new video you did not film: a [Persona Short](/glossary/persona-shorts) that narrates the point on camera with a face-locked avatar. One source becomes captioned, correctly-cropped video everywhere, not one captioned post on one feed.
X updated its native in-app video editor with editable captions. You can edit X's auto-generated captions by hand in the composer, ask Grok to correct them, or tell Grok to change them — including translating them into another language. The refresh also made the editor cleaner and easier to use, and has been shown in the iOS app.
Inside the video composer you can hand X's auto-generated captions to Grok to correct errors, or specify how you want them changed — including translating the caption track into another language — without leaving the app or using a separate tool.
No. Captions and edits you make in X's editor are tied to X's posting flow and player, so re-uploading the file to another platform leaves you re-captioning and re-cropping it by hand. To keep captions on a clip everywhere, burn them into the video — a generation engine like Kompozy does this and reframes per platform.
It only edits video you already recorded — it transcribes, corrects and translates captions, styles overlays, and offers green-screen backgrounds. It generates no net-new footage, avatar, or B-roll. For net-new video (such as a face-locked avatar short), you need a generation tool like Kompozy.
