What it does
THIS IS A SENTENCE. AND THIS IS ANOTHER ONE! is that right? ice cream is nice. becomes This is a sentence. And this is another one! Is that right? Ice cream is nice.
A capital is placed at the start of the text, at the start of each paragraph and after a full stop, exclamation mark, question mark or ellipsis. Tick Every line starts with a capital if each line is its own sentence, such as in a list.
Names and "I"
The tool lowercases everything first, so proper nouns, acronyms and the pronoun "I" become lowercase as well (london, nasa, i). Check the result for those and correct them by hand. To capitalise every word instead, use capitalize each word.
