Frequently asked questions

What is the difference between Title Case and sentence case?
Title Case capitalizes the first letter of every word. Sentence case lowercases everything, then capitalizes the first letter after the start of the text or a period, question mark, or exclamation mark.
Does Title Case follow AP or Chicago style?
No. It capitalizes every word and does not leave small words like “and” or “the” lowercase. For published headlines, do a final pass by hand.
Is the text sent to a server?
No. Case conversion runs locally in your browser.
