Frequently asked questions
Which title case style should I use?
Journalism usually uses AP, academic papers use APA, and books and many websites use Chicago. Match your publication's style guide.
Why is 'with' capitalized in AP but not Chicago?
AP only lowercases prepositions of three letters or fewer, while Chicago lowercases all prepositions such as 'with', 'from' and 'into'.
Are acronyms and brand names kept?
Yes. Words with inner capitals such as iPhone or NASA are left exactly as you typed them.
