Archimedes is a Markdown editor designed to make mathematical writing easy with inline LaTeX support.


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.


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.


Just getting started with LaTeX syntax? 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.


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.


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 or HTML document to disk.

Great Editor, not perfect though

I have been using this app daily and it really is an awesome editor and piece of software, However, I would like to see stuff such as the ability for a dark mode or choose different colorschemes. I also think the ability for other fonts would be a cool idea. Love the app so far though!

Great for learning LaTeX math, but needs more export options

I’ve dabbled in LaTeX before using Archimedes, but this app has rekindled my interest in using LaTeX.

Markdown is powerful enough for the majority of my formatting needs. However, my notes often include equations which do not translate well to Markdown. The support for LaTeX math finally enables me to express complex mathematical equations embedded in simple markdown formatting. In doing what it claims to do, Archimedes gets top marks.

However, my usual note-taking workflow is to write all my notes in Sublime Text 2 or Editorial on the iPad and then export them to Evernote. Archimedes’ export options are comparatively slim, and in my opinion that keeps it from being the perfect app.

I use this app every day - highly recommended.

Archimedes is very, very good at what it does. Some have pointed out that it’s not a full featured LaTeX tool; true, but there are many tasks that call for a short note, letter, email or even a brief article and these can be done quickly and efficiently with Archimedes. A math form reference, a math symbol finder, and command completion are all built-in and are as good or better than anything I’ve tried. I appreciate that I don’t have to leave the OSX infrastructure to write.

I have recommended this to colleagues and students, even those who are not experienced with TeX, and they are always amazed that, for a very modest price, they can load one app and be productive right from the start. Another big positive for me is that Archimedes’ rendered PDF is quite good: clean, modern and readable.

I highly recommend this app, and I hope Matt Rajca continues development of this excellent product.
