Change capitalization in an editable text draft. Uppercase and lowercase convert the whole input; title and sentence case use simple character rules. The result replaces the text in the editor, so keep a copy before changing names, acronyms or identifiers.
lightbulb When to use this tool

Input: Plain text and a case button.
Output: Edited text with copy/clear.

Examples
science Title case is mechanical
NASA launch becomes Nasa Launch. Restore NASA manually if you need the acronym; the tool does not maintain a dictionary of names.
science Sentence boundaries
HELLO WORLD. NEXT LINE becomes Hello world. Next line. A period without a following space is not treated as the same boundary by this simple rule.
Limitations
Simple JavaScript rules are not language-aware style editing. Acronyms/names need review; original casing is overwritten.
