questions
how does title case work?
headline style: main words get capitals, short words like "of", "the" and "and" stay lowercase unless they come first or last.
will it keep acronyms like nasa?
yes in title and sentence case — but a whole run of capital words is treated as shouting and converted.
is my text uploaded?
no — everything happens in your browser.
