At this point in time the tools on this site are entirely dependent on JavaScript. Given enough time and money it is hoped to develop a version in the future which will be able to operate independently. Since JavaScript runs on your own computer, rather than on this server, it has been possible to set up this site much more quickly than if a server-side language was used, and it is possible to serve far more pages with the available bandwidth.

Simple Palindrome
A word, phrase or sentance that reads the same forwards as it does backwards, ignoring all non-alphabetic characters.
For example: "1. A Toyota" is a simple Palindrome, since the space, capital letters and full stop / period are all ignored.
Strict Palindrome
A word, phrase or sentance that reads exactly the same forwards as it does backwards, including all non-alphabetic characters.
For example: "A Toyota" is not a strict Palindrome, since the space character occurs only once.
