Title Case API
Convert a heading to proper headline (title) case the way editors do — not a naive capitalise-every-word. It capitalises the first and last words and all the major words, while keeping articles (a, an, the), coordinating conjunctions (and, but, or…) and prepositions lowercase, and always capitalises the word right after a colon. Choose AP style (lowercases short prepositions, capitalises longer ones) or Chicago style (lowercases prepositions of any length). Hyphenated compounds such as well-known and state-of-the-art are handled correctly. Perfect for article and blog titles, headings, SEO meta titles, product and section names, and CMS tooling. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. Distinct from a plain title/sentence case converter, which capitalises every word.
