Frequently asked questions
What does Sentence case do with multiple sentences?
It capitalizes the first letter after the start of the text and after each ., !, or ?, and lowercases everything else — so multi-sentence paragraphs get every sentence capitalized correctly, not just the first.
What is aLtErNaTiNg case for?
It's a novelty format (sometimes called "sarcasm case" or "spongebob case") that alternates upper and lower case letter by letter — mostly used for jokes or emphasis on social media.
