About Text tools
A free set of tools for working with text — count characters, diff two texts, format JSON, test regular expressions, and generate passwords. Your input is never sent to a server and is processed entirely in the browser.
They help check manuscript length, review code and data, and create strong passwords. Ideal for writers, engineers, students, and anyone who works with text and data every day.
