Archimedes Editor1.7.4 - App Store

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

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 and the Format Bar floating above the keyboard, 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, 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.

MAGIC TYPE

Just getting started with LaTeX syntax? Don't know the code for the asymptotically equal symbol? Just 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 select a custom theme, and Dark Mode is fully supported. Themes come with various font faces.

MATH LIBRARY

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

NAVIGATOR

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

IMAGES

Insert images from your Photos library, via the Document Camera, or by drawing sketches right inside the document.

DOCUMENT SYNC

Archimedes is the only app of its kind that supports syncing documents via iCloud with its Mac counterpart.

SHARING

SEARCH

Use the Find bar to quickly find text in any document.

STATISTICS
