Capitalisation by the rules

Case conversion is full of edge cases: acronyms like NASA, brands like iPhone, Turkish dotted İ, German ß, Greek final sigma, and style guides that disagree about which small words to capitalise. These converters handle them, and the title case tool follows APA, Chicago, AP, MLA, New York Times and Wikipedia rules. See the title case guide.
