Frequently asked questions
Does sentence case capitalize names and places?+
No. It only capitalizes the first letter after a period, question mark, or exclamation mark (plus the pronoun ‘I’). Proper nouns like names, brands, and cities need to be capitalized manually afterward.
What counts as a new sentence?+
Any run of text following a `.`, `!`, or `?` followed by whitespace is treated as the start of a new sentence.
