Frequently asked questions

Does it work with other languages?

Yes. Upper and lower case follow the rules of letters in many languages, such as Spanish, German and Turkish. Scripts without upper and lower case, like Hindi or Chinese, stay as they are.

What is the difference between Title Case and Sentence case?

Title Case capitalises every word. Sentence case capitalises only the first word of each sentence.

What are camelCase and snake_case for?

They are naming styles used in programming for variables, files and web addresses. They join words without spaces.

Can it tidy my text too?

Yes. It can remove extra spaces and line breaks, sort lines, remove duplicate lines, and reverse the text.

Is my text uploaded?

No. Everything happens in your browser.
