Frequently Asked Questions
Title Case capitalizes the first letter of each word while preserving the rest as-is: "hello WORLD" → "Hello WORLD". Capitalized Case (also called Proper Case) capitalizes the first letter of each word and lowercases the rest: "hello WORLD" → "Hello World". For already-properly-cased text, the results are identical.
Sentence case capitalizes the first letter of each sentence and lowercases everything else. Sentence boundaries are detected at ., !, and ? followed by a space. The tool also handles the very start of the text as a sentence boundary.
Alternating case (also called sponge case or mocking case) alternates between uppercase and lowercase letters within words. It is commonly used in meme culture to convey sarcasm or mockery in text. Each letter alternates regardless of word boundaries.
