X has updated its built-in video editor: you can now edit a clip's subtitles right inside the app, and the platform's AI, Grok, can correct errors or translate them into another language. For a creator, this is a free way to repurpose the same video for multiple audiences at once, without using third-party services or paying extra.
What Exactly Has Changed
The update was announced on October 4, 2026, by X developer Allegra Iacchia in a post on the platform. Her announcement was picked up by Social Media Today and Social Samosa. We couldn't access the original post—X blocks content for users who aren't logged in—so the following quotes are based on those reports.
Subtitles Can Now Be Edited Manually
X could already auto-generate subtitles from speech, but there was no way to fix them in the editor. A misspelled name, term, or brand would just go straight to the feed. Now, the generated text can be edited directly in the video upload window.
Grok Corrects and Translates
Instead of editing by hand, you can turn to the integrated AI, Grok. According to the developer's description, you can ask it to:
- correct recognition errors throughout the text;
- change something specific, just by explaining it in plain language;
- translate the subtitles into another language.
The translation feature is the biggest news here. A clip spoken in one language, with English or Spanish subtitles, can now be understood by a foreign audience without needing a voice-over or a reshoot.
The Interface Is Simpler
The editor, in the developer's words, is now "cleaner, clearer, and much more comfortable." The announcement doesn't specify what exactly has been redesigned.
What's the Point of All This?
The platform's logic is simple: "Subtitles are one of the easiest ways to keep a viewer watching, especially when so many people watch videos with the sound off" (quote via Social Samosa). A clip in the feed usually starts silently, and the on-screen text is what determines whether a user watches it through or just scrolls past.
The Third Editor Update This Summer and Fall
X has been polishing its built-in editor for several months now:
| When | What Was Added |
|---|---|
| July 2026 | Multilingual subtitles and green screen recording (iOS first) |
| August 2026 | Video overlays |
| October 2026 | Manual subtitle editing, Grok correction and translation, new interface |
The direction is clear: the platform wants editing to happen inside the app, so creators don't have to turn to external software.
What to Do If You're a Creator
- Review your subtitles before publishing. Auto-recognition almost always messes up names, brands, and industry jargon. Now you can fix that in thirty seconds instead of it being a permanent error.
- Test the translation on a single clip, not all of them. Take a video that has already performed well in your language, add English subtitles, and see what happens to your retention and reach.
- Write short lines. A long sentence will get even longer when translated and can cover up the visuals.
- Proofread the auto-translation yourself. Grok will do the translating, but you're responsible for the meaning. It might translate jargon, jokes, and names too literally.
- Don't rely on subtitles as your only text. The description and the first few seconds of the clip still need to be in the audience's language.
What to Do If You're a Brand
If you commission videos from creators, add a line to your brief about subtitles: what language they should be in, whether they're needed, and how to spell the company name. It's no extra effort for the creator and prevents the most common error: a misspelled brand name.
What We Still Don't Know
Frankly, here's what the announcement didn't mention:
- which languages Grok translates to: no list has been published;
- whether an X Premium subscription is required: no limits were mentioned, but it also wasn't explicitly called "a feature for everyone";
- if it works on Android and the web: this summer's editor updates were rolled out on iOS first;
- how the algorithm treats translated subtitles: there have been no concrete promises about reach.
If X clarifies any of these points, we'll update this article.
Frequently Asked Questions
How do I make free video subtitles?
If you're posting the clip on X, you can do it right in the built-in editor. The platform auto-detects speech, and you can either fix the text manually or ask Grok to do it. It's free. For other platforms, there are separate free tools; we cover them in our review of AI editors.
Can you automatically translate subtitles into English?
On X, yes—using Grok, right in the video upload window. The translation is automatic, so it's a good idea to proofread the result before publishing.
Do subtitles really increase views?
There are no direct numbers from X. The platform justifies the update by saying that most viewers watch videos with the sound off. For those viewers, on-screen text is the only way to hold their attention.
Is a subscription required to edit subtitles?
The announcement doesn't say. If you have a standard account and don't see the feature, the update most likely hasn't rolled out to your version of the app yet.
How is this different from subtitle features in other software?
The main difference is that everything happens in a single window before you publish. You don't have to export a file, run it through a third-party service, and then re-upload it.

Free subtitle translation removes one of the main barriers to reaching a foreign audience, making the same video ready for multiple markets at once.
