ConTeXt is a general-purpose document processor. It is especially suited for structured documents, automated document production, very fine typography, and multi-lingual typesetting. It is based in part on the TeX typesetting system, and uses a document markup language for manuscript preparation. The typographical and automated capabilities of ConTeXt are extensive, including interfaces for handling microtypography, multiple footnotes and footnote classes, and manipulating OpenType fonts and features. Moreover, it offers extensive support for colors, backgrounds, hyperlinks, presentations, figure-text integration, and conditional compilation. It gives the user extensive control over formatting while making it easy to create new layouts and styles without learning the low-level TeX macro language.

ConTeXt may be compared and contrasted with LaTeX, but the primary thrust of the two are rather distinct. ConTeXt from the ground up is a typography and typesetting system meant to provide users easy and consistent access to advanced typographical control—important for general-purpose typesetting tasks. The original vision of LaTeX is to insulate the user from typographical decisions—a useful approach for submitting, say, articles for a scientific journal. LaTeX has evolved from that original vision; at the same time, ConTeXt’s unified design avoids the package clashes that can happen with LaTeX.

ConTeXt provides a multi-lingual user interface with support for markup in English, Dutch, German, French, and Italian and support for output in many languages including western European, eastern European, Arabic-script, Chinese, Japanese, and Korean. It also allows the user to use different TeX engines like pdfTeX, XeTeX, and LuaTeX without changing the user interface.

As its native drawing engine, ConTeXt integrates a superset of MetaPost called MetaFun, which allows the users to use the drawing abilities of MetaPost for page backgrounds and ornaments. Metafun can also be used with stand alone MetaPost. ConTeXt also supports the use of other external drawing engines, like PGF/TikZ and PSTricks.

ConTeXt also provides a macro package for typesetting chemical structure diagrams with TeX called PPCHTeX, as well as many other modules. This package can also be used with plain TeX and LaTeX.
