This simple application will help building regular expressions, a.k.a. regex, with the help of a graphical user interface (GUI). You don't have to memorize complicated rules and grammar, just tick and type what you are looking for and the regex will be generated for you.

It also provides a Cheat Sheet to look up more complicated regex rules.

Enjoy!
