Frequently asked questions
What is the difference between the styles?
AP and APA lowercase only short articles, conjunctions and prepositions of three letters or fewer. Chicago and MLA lowercase every preposition, however long, so "between" stays lowercase.
Which words are always capitalized?
The first word, the last word, and the first word after a colon, in every style.
What about words like iPhone and NASA?
Words with capitals inside them and all-capital acronyms are left as you typed them.
Can I convert many titles at once?
Yes. Put one title on each line. Each line gets its own first and last word.
Does it follow my style guide exactly?
It follows the common rules, but guides have special cases and exceptions. Check yours for unusual titles.
Is my text sent anywhere?
No. Everything runs in your browser, so your text never leaves your device.
