Frequently asked questions
What's the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence, like normal prose.
Does this handle punctuation correctly?
Sentence case capitalizes the letter after sentence-ending punctuation (. ! ?) as well as the start of the text.
Is there a text length limit?
No practical limit — conversion happens instantly in your browser regardless of length.
