Frequently asked questions

How are word boundaries detected?
Spaces, underscores, hyphens, and camelCase transitions are all treated as word boundaries.
What's the difference between Title and Sentence case?
Title case capitalizes every word; sentence case capitalizes only the first word of each sentence.
Does it work with non-English text?
Upper/lowercase use Unicode rules. Programmer cases (camel, snake, …) work best with Latin letters and numbers.
Is my text uploaded?
No. Conversion happens entirely in your browser.
