Frequently asked questions

Is my text sent anywhere?
No. Conversion happens entirely on your device.
How does Title Case decide which letters to capitalize?
It capitalizes the first letter of every word — it doesn't apply style-guide exceptions for short words like "a" or "the".
How does Sentence case work?
It lowercases everything, then capitalizes the first letter of the text and of each new sentence (after a ., ! or ?).
