Uppercase and lowercase use locale-aware browser casing. Title case capitalizes word starts; sentence case capitalizes text starts after sentence punctuation.
重要说明
Automatic title and sentence casing cannot reproduce every language or editorial style rule.
常见问题
Does title case follow a specific style guide?
No. It applies a simple capitalization rule rather than AP, Chicago, or another editorial standard.
Is the original text stored?
No. It remains only in the page unless you copy the result.
