Hi! I’m Arno and I’ve always been interested in typography and in math as a language. At the intersection of science and art, I have crafted MathLive: beautifully typeset math made easy.

When you type a formula, MathLive will:

  • Typeset it beautifully, as TeX would have
  • Generate the LaTeX and MathML markup for it
  • Evaluate it numerically

MathLive is a Javascript library that implements the TeX layout algorithms using modern HTML/CSS and no absolute positioning. It implements a large set of LaTeX commands, including some popular extensions used by MathJAX. It is tested on all modern browsers, on both desktop and mobile devices. It has a rich API that allows extensive customization and extensibility. You can find out more in the MathLive Usage Guide.

I can’t wait to see what you will do with it. Enjoy!

Intuitive Editing

Let's get started! Type an equation: use the keyboard to type symbols, arrow keys to navigate.

When done, select the equation, and copy the LaTeX code to another app

                    "slash" 2a

Inline Shortcuts

Some symbols get converted automatically.

Type pi and it becomes π.

Command Mode

For less common symbols, type \ to enter command mode. In command mode, you can type LaTeX commands and expressions

                    to invoke the command mode, followed by "h", "b" and "return" to select the "hbar" symbol


^ or ctrl+6 superscript
_ or ctrl+- subscript
tab move to the next insertion point
ctrl+5 switch between superscript and subscript
\ command mode: type the first letters of a command to insert it. Press up and down arrow to view the next/previous suggestion
Command/Control+C/V Copy/Paste LaTeX

Use shift+arrow keys to extend the selection.
