What is the difference between AP and Chicago title case?

AP style capitalizes words of four or more letters (including prepositions like "with" and "from") and lowercases shorter prepositions, articles, and conjunctions. Chicago style lowercases all prepositions regardless of length, as well as articles and coordinating conjunctions, unless they are the first or last word.

Does APA title case differ from Chicago?

Yes. APA capitalizes major words — nouns, verbs, adjectives, adverbs, and pronouns — and lowercases articles, short prepositions (under four letters), and short conjunctions. APA also capitalizes the first word after a colon or dash in a title.

How are hyphenated words handled?

Chicago style capitalizes both parts of a hyphenated word if both parts would be capitalized on their own (e.g., "Self-Confidence"). AP and MLA capitalize the first element and subsequent major elements. This tool follows each style's standard hyphen rules automatically.

What words are always capitalized regardless of style?

The first and last words of any title are always capitalized in every style. Proper nouns (names of people, places, brands) should also always be capitalized, though this tool relies on you to mark them correctly in your input.
