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.
