X has updated its built-in video editor. You can now edit subtitles directly within the app, and the platform's Grok AI can correct errors and translate them into other languages. This gives creators a free way to adapt a single video for multiple audiences—no third-party services or extra fees required.
What Exactly Changed
The update was announced on October 4, 2026, by X developer Allegra Yaccia in a post on the platform; her announcement was covered by Social Media Today and Social Samosa. We were unable to access the original post—the platform requires a login to view content—so the quotes below are cited from these publications.
You Can Now Edit Subtitles Manually
Previously, X would auto-generate subtitles, but you couldn't edit them in the editor. Any errors in names, terms, or brand mentions would go live in the feed. Now, the generated text can be edited directly in the video upload window.
Grok Corrects and Translates
Instead of editing manually, you can turn to the built-in Grok AI. According to the developer, you can:
- ask it to fix all recognition errors;
- explain in your own words what to change in the text;
- translate the subtitles into another language.
Translation is the key feature here. A video in Russian with English or Spanish subtitles can be understood by an international audience without a new voice-over or a reshoot.
The Interface Is Now Simpler
The editor itself, according to the developer, has become "cleaner, clearer, and noticeably more convenient." The announcement provides no specifics on what exactly was redesigned.
Why Does This Matter?
The platform's logic is simple: "Subtitles are one of the easiest ways to retain a viewer, especially when so many people watch videos with the sound off" (quote via Social Samosa). Videos in the feed often autoplay on mute, and the on-screen text determines whether a viewer will watch through or scroll past.
This Is the Third Editor Update This Summer and Fall
X has been improving its built-in editor for several months now:
| When | What Was Added |
|---|---|
| July 2026 | Multilingual subtitles and green screen recording (initially on the iOS app) |
| August 2026 | Video overlays |
| October 2026 | Manual subtitle editing, correction and translation via Grok, new interface |
The direction is clear: the platform is building up its in-app editing suite to keep creators from using third-party programs.
What Creators Should Do
- Check your subtitles before publishing. Auto-recognition consistently misspells names, brand mentions, and professional jargon. Now, these mistakes can be fixed in thirty seconds instead of being permanent.
- Test the translation on one video first, not all at once. Take a video that has already performed well in Russian, add English subtitles, and see what happens to your watch time and reach.
- Write in short lines. A long phrase in the subtitles becomes even longer when translated and can obscure the video.
- Proofread the machine translation. Grok will do the translating, but you are responsible for the meaning: it might translate slang, jokes, and names too literally.
- Don't rely on subtitles as your only text. The video's description and hook still need to be in the target audience's language.
What Brands Should Do
If you commission videos from creators, add a line about subtitles to your brief: specify the language, whether they are needed at all, and the correct spelling of your company's name. This is free for the creator and eliminates the most common revision request: a misrecognized brand name.
What We Still Don't Know
Here's what the announcement didn't cover:
- Which languages Grok can translate to — no list has been published.
- Whether an X Premium subscription is required — no limitations were mentioned, but it wasn't explicitly called a feature "for everyone" either.
- If it works on Android and the web — the summer editor updates were initially released only on iOS.
- How the platform's algorithm treats translated subtitles — there were no specific promises regarding reach.
If X clarifies any of these points, we will update this article.
Frequently Asked Questions
How can I get free subtitles for my videos?
If you're posting a video on X, you can do it right in the built-in editor: the platform recognizes speech automatically, and you can edit the text manually or ask Grok to do it. There's no charge for this. For other platforms, there are separate free tools, which we covered in our review of AI editors.
Can I automatically translate subtitles into English?
Yes, on X you can use Grok right in the video upload window. The translation is machine-generated, so you should proofread the result before publishing.
Do subtitles really increase views?
There are no direct numbers for X. The platform explains the update by stating that most viewers watch videos with the sound off—for this audience, on-screen text is the only way to hold their attention.
Do I need a subscription to edit subtitles?
This was not mentioned in the announcement. If you have a standard account and the feature hasn't appeared, the update likely hasn't rolled out to your app version yet.
How is this different from subtitles in other programs?
The main difference is that everything happens in a single window before you publish: you don't need to export a file, run it through a third-party service, and re-upload it.
