Archimedes 1.3.2 – Markdown and LaTeX editor.


Archimedes is a text editor that uniquely combines Markdown and LaTeX to make mathematical writing fun and easy.

Markdown Editing
At its core, Archimedes is a fully-featured plain text and Markdown editor. It includes a fast syntax highlighter and provides convenient keyboard shortcuts for common actions, such as inserting images and links. With complete support for Markdown, Archimedes makes formatting and structuring documents elegant and easy.

Math Mode + Autocomplete
In Math Mode, Archimedes lets you write mathematics in a subset of LaTeX. Just enter $$ to get started. Over 700 intuitive commands, such as sqrt{a^2 + b^2}, help you produce stunning mathematical output. Archimedes even autocompletes commands and intelligently matches closing braces, brackets, and parenthesis as you type.

Magic Type
Just getting started with LaTeX? Don’t know the code for the asymptotically equal symbol? Use your MacBook’s trackpad or Magic Trackpad to draw it! Archimedes will recognize the symbol and insert the corresponding code for you.

Live Preview:
As you work, a beautifully-typeset live preview of your document is always visible. You can even switch between horizontal or vertical orientation and select a custom theme.

Math Library
Browse the math library to see all available LaTeX commands and their previews in one place.

Archimedes lets you define macros — or custom commands — for the expressions you work with the most. Macros show up in autocompletion results right alongside built-in completions.

Working on a long document? Use the Navigator to pull up a table of contents and quickly jump between sections.

Share your work with the rest of the world via email, iMessage or AirDrop. Or export a PDF document to disk.
