How it works
CaptionX is a subtitle generator built into the Adobe Premiere Pro extension panel. Subtitle generation happens inside your editor — no uploads, no browser tabs, no reimport.
Create a free account, download the plugin, and open the CaptionX extension panel inside Adobe Premiere Pro.
Select the clip you want subtitled, pick your language from 57+ options, and configure your subtitle style.
CaptionX transcribes your audio using AI and generates timed subtitles. Export as SRT for any platform or place the captions directly into your Premiere Pro timeline.
Subtitle generation tools that live outside your editing software add steps, not value. CaptionX removes the round-trip.
Most subtitle generators handle English well and degrade for other languages. CaptionX generates accurate subtitles in 57+ languages — including Arabic, Hindi, Urdu, Indonesian, Thai, Vietnamese, Japanese, Korean, and more — making it usable for creators regardless of what language they produce in.
Standalone subtitle generators require you to upload your video to a website, wait for processing, download the file, and import it back into your project. CaptionX generates subtitles inside Adobe Premiere Pro — the whole process stays in your existing workflow.
CaptionX exports a properly formatted SRT file that works with YouTube, Vimeo, and every major platform. No formatting, no manual timecode editing, no conversion step required before upload.
