Auto-generate captions
CaptionX transcribes your audio using AI and produces accurate, timed captions — placed directly in your project. Export as SRT for YouTube or any other platform.
Why use CaptionX as your auto caption generator
Most auto caption generators are standalone web tools that add steps to an already complex editing workflow. CaptionX removes that friction.
57+ language coverage
Most auto caption generators work well for English and struggle outside of that. CaptionX generates accurate captions in 57+ languages, including Arabic, Hindi, Urdu, Indonesian, Thai, Vietnamese, and many more.
No upload, no context switch
External caption generators require uploading your video, waiting, downloading a file, and importing it back. CaptionX works inside Adobe Premiere Pro — the auto caption generation happens where your edit already lives.
Honest positioning
Free means free — not a trial that requires a card
CaptionX includes 10 auto caption generations per month for free. No card required to start. If your edit volume grows beyond the free plan, upgrade — but you can use the auto caption generator at no cost from day one.
