Fun Facts

• There are at least 5 competing title-case styles: AP, Chicago, MLA, APA, and NYT. Each one capitalises a slightly different set of short words.
• The word 'the' is the most common English word, appearing in ~7% of all text — and title case rules for it vary by every style guide.
• German capitalizes all nouns (not just proper nouns), making German title-case algorithms fundamentally different from English ones.

FAQ

What style does it follow?

AP style: capitalize all major words, leave articles (a, an, the), conjunctions (and, but, or, nor), and short prepositions (in, on, at, to) lowercase. First and last words always capitalized.

Can I pick Chicago style instead?

Yes — Chicago capitalizes prepositions of 5+ letters (among, between). AP keeps them lowercase. Toggle between the two styles.

Does it handle hyphenated words?

Both parts are treated as separate words. 'Mother-in-law' → 'Mother-in-Law' (first capital each, preposition stays down).

What about acronyms?

The tool preserves ALL-CAPS tokens (USA, NASA, URL). Toggle 'force title case on acronyms' if you want to normalize them.
