Frequently asked questions
What is the difference between capitalize and title case?
Basic capitalization uppercases every word’s first letter regardless of length; title case applies style rules like keeping "and" and "of" lowercase.
Can I capitalize only sentences?
Yes — choose the "sentence" mode and only the first letter of each sentence is capitalized.
