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

Do you want to use the MathLive Javascript library in your own web projects? Check out the MathLive Usage Guide. I can’t wait to see what you will do with it. Enjoy!


This is a work in progress. I invite you to contribute by reporting issues and providing feedback and to contact me at You are also welcome to contribute code to the project on GitHub.

Simple Editing

Let's get started! Type an equation. Copy the LaTeX code to another app.

Use the keyboard to type symbols, arrow keys to navigate.

            -b+- "\"sq option "v" b "shift" 6 2 "spacebar" -4ac "tab" "command" "A"
            "slash" 2a

Auto Converted

Some symbols get converted automatically.

Type pi and it becomes π.

            replaced with the symbol "pi"

Command Mode

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

Screen capture of typing backslash
            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.
