Tait’s Simple Markdown Tool

Info

You can use $...$ for inline math.
You can use $$...$$ for “display mode” math.
Display mode will make the equation take up an entire line for itself, and it will display larger and more “formally”. It also allows you to have newlines without breaking up the expression, and/or the use of \newline to have a multi-line formula.
You can save the HTML or markdown for future use.
You can download the HTML or markdown for sharing with others.
Saving will save it to your browser’s local storage so when you load the page again–even after a reboot–it will be pre-populated with what you saved last.
Converting to HTML automatically saves both the markdown and the HTML.
