Create Subtitles for Your YouTube Videos
YouTube's automatic captions are convenient but often inaccurate — and errors in captions hurt watch time, accessibility, and how your content is indexed. Uploading your own accurate SRT file fixes all three.
Upload your video file to Jackob.ai before (or after) publishing, review the transcript with the synchronized player, and download a properly timed SRT or VTT file to attach to your YouTube upload. You also get the full transcript for descriptions, chapters, and blog versions of the video.

Frequently asked questions
How do I add an SRT file to a YouTube video?
In YouTube Studio, open the video, choose Subtitles, select the language, and upload the SRT file downloaded from Jackob.ai. YouTube applies your captions in place of the automatic ones.
Why not just use YouTube’s automatic captions?
Automatic captions frequently mangle names, technical terms, and non-English speech, and they offer no review step. Uploading a corrected SRT improves accessibility, viewer experience, and search indexing of your content.
Can I make subtitles in a different language than the video?
Jackob.ai transcribes the original language of the video, and text translation is available on paid plans — useful for reaching international audiences.
