Uses
This editor was written with two main uses in mind. Others may occur to you.

You can send messages with mathematical notation by copying the contents of the "Type" field into your mail client. The recipient can then come to this page and paste in your message to the "Type" field and read the formatted version in the "Display" field.
 XHTML+MathML

You can produce XHTML+MathML documents that can be viewed on a variety of browsers (even without JavaScript support): click the "View MathML" button, copy the output to a text editor, and save as an xhtml file.

The original ASCIIMathML version of the page is included as a comment at the top of the webpage in case the page requires further editing at a later stage. The editor also ensures that users of ASCIIMathML are not locked into the specific ASCII (or LaTeX) syntax, but are free to convert their files to standard Presentation MathML when this is convenient.
Note that this is dynamic HTML running locally on your machine! If you leave or refresh this page before copying and saving your work it will, in all likelihood, disappear.
