About Ruzby

Ruzby is a collection of small, fast tools for everyday questions: word games, planning helpers and simple calculators. Every tool works in your browser, without an account.

We build each tool around one job and explain how it works on the same page, so you can check the method as well as the answer. Word tools use the public-domain ENABLE word list. Calculators show the assumptions they use.

The site is free to use and supported by advertising. If something is wrong or you have an idea for a tool, get in touch.
