FAQ
What is sentence case?
Sentence case is a style where the first letter of a sentence is capitalized, and the rest of the words are lowercase, except for proper nouns and the word "I". It is the most common way to write in English.
Does this tool handle proper nouns?
No, it does not. It only applies the general rules of sentence case. You will have to capitalize any proper nouns yourself.
What happens to text that is already in sentence case?
The tool will still process it. It will make everything lowercase first and then apply the sentence case rules again. This can help fix any mistakes in the original text.
