CaptionX auto-generates accurate subtitles directly inside Adobe Premiere Pro. Transcribe your audio in 57+ languages, place timed subtitles in your timeline, and export SRT files for YouTube and beyond — without leaving your editing workflow.
Free to start — no credit card required.
How it works
CaptionX is an extension panel inside Adobe Premiere Pro. The auto subtitle generation happens inside your editor — there is no upload, no waiting for a browser tool, and no reimport step.
Create a free account, download the plugin, and open the CaptionX extension panel inside Adobe Premiere Pro.
Select the clip you want subtitled, choose your language from 57+ options, and set your caption preferences.
CaptionX transcribes your audio using AI and places timed subtitles into your project. Export as SRT for YouTube or use the captions directly in your Premiere Pro timeline.
External subtitle generators add friction at every step. CaptionX removes that loop by auto-generating subtitles where your editing work already lives.
Most auto subtitle generators support English well and a handful of other languages. CaptionX auto-generates subtitles in 57+ languages — including Arabic, Hindi, Urdu, Indonesian, Thai, Vietnamese, and many more — so your content is subtitled regardless of what language you produce in.
Standalone subtitle generators require uploading your video to an external site, waiting, downloading, and importing back into your project. CaptionX auto-generates subtitles inside Premiere Pro — no file transfers, no browser tabs, no interruption to your workflow.
CaptionX exports auto-generated subtitles as SRT files ready to upload to YouTube, Vimeo, or any platform. The file is correctly formatted and doesn't require manual editing before upload.
