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.

Good, but multiline equations don’t work?

I have to do this in Archimedes:
$$ T = \begin{bmatrix} 1 & 0 & t_x \\ 0 & 1 & t_y \\ 0 & 0 & 1 \\ \end{bmatrix} $$

Why can’t one do this like in MathJax?
\\[T = \begin{bmatrix}
1 & 0 & t_x \\
0 & 1 & t_y \\
0 & 0 & 1 \\

Never mind, the \\[ … \\] syntax, which is just like $$ .. $$ in Archimedes, but the fact that you can’t break an equation into lines bothers me.
Multiline support would greatly enchance the ablity to structure equations in a way that’s easier to read.

Also, drawing a symbol only works with touchpad, and it lags significanlty. It’s not real-time at all. You draw a symbol with your finger and see it slowly appear on screen.
And what’s wrong with not allowing to use a mouse to draw symbols? Don’t get me wrong, this feature is a good idea, but the implementation needs more work.

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.

Concerns about new non-standard file format

The latest version saves files in a “new, more capable” and “future-proof, package-based” file format. This is exactly what I don’t want. Latex and markdown in ascii files ARE future proof. I specifically want files that can be edited on, say, an iPad and is accessible on some other device belonging to collaborators who don’t use macs. The release notes do say that ascii files may still be used, but new features may not be available. This is exactly the sort of fragmentation Latex and markdown try to avoid, and I think it is unwise for a small developer to introduce a new file format to wrap around them, however well-meant. My previous review was 5-star, but no to this version.
