Utilities: Calculators and Tools
Word counter and secure password generator, right in your browser.
Not every useful tool involves numbers. Sometimes you just need to know whether your text fits the character limit, or to create a strong password without relying on an unknown website.
The utilities in this category run entirely in your browser. The text you paste and the passwords you generate are not sent to any server, and that is part of what makes these tools trustworthy.
