Who this is for
Built for video editors, podcast producers, and content teams who already have caption files but the timing drifts — typical after re-edits, format conversions, or when machine-translated subtitles need realignment to the original audio. Skip the subtitle-editor learning curve; drop in the file, see what's broken, and (with a free account) get a corrected file back.
