FAQ

What is the difference between "First letter" and "Sentence case"?

First letter capitalizes only the first letter of the whole text; Sentence case capitalizes the first character after each sentence (ending with . ! ? or Chinese punctuation).

Will "Title case" process Chinese?

No. It only capitalizes the first letter of English words; Chinese and digits are unaffected.
