Frequently asked questions
What is the difference between Title and Capitalized Case?
Capitalized Case capitalises the first letter of every word. Title Case does the same but keeps short joining words (a, of, the…) lowercase unless they start the title.
Does Sentence case fix every sentence?
It lowercases the text then capitalises the first letter of each sentence. Proper nouns are not detected, so a quick review is wise.
