What is the main difference between Chicago and AP title capitalization?

The Chicago Manual of Style lowercases prepositions of any length (unless first/last), whereas AP style capitalizes any preposition with four or more letters (like "With", "About", "From").

Are the first and last words of a title always capitalized?

Yes! Across all style manuals (APA, Chicago, MLA, AP), the very first word and the very last word of a headline are always capitalized regardless of part of speech.

How does it handle subtitles after a colon (:)?

The first word following a colon, em-dash, or question mark is always capitalized as the beginning of a subtitle.

Does this tool preserve acronyms like NASA or API?

Yes, existing all-uppercase abbreviations are preserved without distortion.
