You wrote the words. Paste them once and CaptionFit times every line to the recording, so there is nothing to correct afterwards.
Fix spelling swaps in your wording while keeping every caption's timing. Fix spelling & re-segment rebuilds the captions so each line of your lyrics becomes one caption.
Artist names, brand names, invented words and heavy accents are the things transcription gets wrong. Your text fixes all of them at once.
After the fix, word-level timings are recomputed from the corrected text, so karaoke highlighting still lands on the right syllable.
Script Fix costs nothing extra. Run it as many times as you need.
Paste a screenplay, a sermon outline or a lecture script. The same alignment fixes character names, verse references and technical terms.
Transcription hears sounds; you know the words. That gap is widest exactly where it hurts most: a chorus with an invented word, a song title, a guest's surname. Rather than hunting through the transcript, paste the text you already have and let alignment do the tedious part.
Lyrics sync is the natural companion to automatic captions for anything scripted, and the foundation for karaoke captions, which highlight one word at a time and therefore need every word to be right.
It is the feature musicians and filmmakers reach for first.
