Use Sentence Case when copied text has inconsistent capitalization and should read more like normal writing. This page is useful for notes, pasted drafts, rough AI output, and mixed-case content that needs a cleaner default style.
Sentence Case is best when the text is readable but visually inconsistent. It helps with lines that were typed in all caps, pasted in all lowercase, or copied from sources that did not preserve normal capitalization.
Uppercase and lowercase force one rigid casing style. Sentence Case is softer. It aims to make the text look more like normal sentence-based writing without turning everything into all caps or all lowercase.
Sentence Case works best after the obvious formatting noise has already been cleaned. Many people use it after removing bullets, line breaks, or extra spaces so the final output reads more naturally.
