Archimedes is a Markdown and LaTeX editor built from the ground up for the Mac and designed to make mathematical writing fun and easy.

Other Platforms

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.

# BuoyancyIn science,**buoyancy**is an upward force exerted by a fluid that opposes the [weight](https://en.wikipedia.org/wiki/Weight) of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

In Math Mode, Archimedes lets you write mathematics in a subset of LaTeX, making it an approachable LaTeX
editor. 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? 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. Dark Mode is fully supported, and themes come with various font faces.

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.

Browse the documentation to discover how to use all of Archimedes' features effectively. Use examples, screenshots, and helpful tips to learn the ins and outs of the app.

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.

New to TeX? Archimedes checks for errors as you type to help you write error-free mathematical expressions.

View document statistics such as character count, word count, and reading time.

Use the Find panel to find and replace text in any document.

Take advantage of keyboard shortcuts to quickly navigate the app.

The Snippet Editor allows you to typeset mathematical expressions without the overhead of a full Archimedes document. Use the Copy Vector button to export the typeset math as a vector graphic.

Archimedes is a native app built using technologies like Core Animation, PDFKit, Versions, Quick Look, and WebKit, and it takes full advantage of the power of macOS.

★★★★★ **So
Convenient!**

*This is the perfect editor for those who enjoy the simplicity of Markdown, but
need LaTeX for scientific and mathematical writing. The ability to draw symbols and have them
magically turn into escape codes will save you hours of time!*

★★★★★ **I use
this app every day - highly recommended.**

*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.*

★★★★★ **Just
what I was looking for!**

*Easy to use and very fast. One nice feature is that the preview of the
latex/markdown text appears instantly, no need for a compile button. The drop down menu for latex
shortcuts is also handy. The interface is very clear and unobtrusive: you can easily keep this app
out for note taking while working on other things, and it won't clutter the screen with extraneous
toolbars and the like.*
