Does the cleaner change subtitle timing?
Most cleanup rules only change subtitle text. The merge-identical rule can combine neighboring duplicate cues and extend the first cue to the second cue's end time.

Why clean subtitle text?
Subtitle text cleanup is useful after AI transcription, live caption exports, meeting transcripts, vendor deliveries, or copied caption drafts. It removes noise before timing and review work begins.
Clean AI and live-caption output
Generated captions often include repeated words, extra spaces, speaker prefixes, music markers, applause notes, and lines that are too long to read comfortably. Cleaning these issues first makes the file easier to edit, translate, review, and publish.
Preview every change before download
Bulk text cleanup should be reviewable. This tool shows each changed cue with before and after text so you can decide whether the selected rules are appropriate before using the cleaned subtitle file.
Works as a first pass before manual editing
The cleaner does not replace a full subtitle editor. It removes repeated cleanup work so the next step can focus on timing, readability, translation quality, and final review.
