About our Text Tools

Our text tools help writers, students, marketers and developers work with words faster. Count words and characters against a limit, switch text between UPPERCASE, Title Case or camelCase, and spot the differences between two versions line by line.

Every tool runs locally in your browser, so your text is never uploaded and the results appear instantly as you type — no sign-up, no waiting, no limits.
