Turn messy, all caps or randomly cased text into clean sentence case, where only the first letter of each sentence is capitalized and everything else is lowercase. This is exactly what you want when you paste something written IN ALL CAPS, fix a shouty comment, or normalize text that came in with inconsistent casing. The converter detects sentence boundaries at periods, question marks and exclamation points, capitalizes the letter that starts each new sentence, and also capitalizes the standalone word I so it reads naturally. It processes your text line by line and paragraph by paragraph so the structure is preserved. Everything runs locally in your browser, so even long or sensitive passages are converted instantly and are never uploaded to a server.
