Frequently asked questions

What's the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word; Sentence case only capitalizes the first letter of each sentence.

Can I use this for code variable names?

This tool is built for regular prose casing — for camelCase or snake_case variable naming you'd want a dedicated code-casing tool.

Does it work on long paragraphs?

Yes, there's no practical length limit — everything is processed instantly in your browser.
