Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word. Sentence case only capitalises the first letter of each sentence, like normal writing.

Does it work with letters like ä, é or ß?

Yes. The conversion uses your language’s rules, so accented and special letters are handled correctly.
