What is sentence case?

Sentence case capitalizes only the first letter of each sentence and proper nouns, similar to how you'd write normal prose.

Does it detect proper nouns?

Currently it capitalizes the first letter after sentence-ending punctuation (. ! ?). Proper noun detection requires NLP and is not included.

Use sentence case for body text, descriptions, and informal content where Title Case feels too formal.
