Title Case capitalizes the first letter of major words — nouns, verbs, adjectives — while keeping minor words like articles (a, an, the), conjunctions (and, but, or), and short prepositions (in, at, by, of) lowercase unless they open the title. This tool applies AP Style / Chicago Manual rules automatically.
Title Case — Blog titles, YouTube names, email subjects.
UPPERCASE — Labels, CTA buttons, bold emphasis.
lowercase — Casual social media, hashtags, modern brand styling.
Sentence case — Body copy, captions, descriptions.
AP Style is commonly used in journalism and news, capitalizing most words but keeping short prepositions (under four letters) lowercase. Chicago Style is typically used in book publishing and keeps almost all prepositions lowercase, regardless of their length.
Generally, articles (a, an, the), coordinating conjunctions (and, but, for), and short prepositions (in, on, at, to) are not capitalized unless they are the first or last word of the title.
