\section*{Introduction to online
LaTeX}

{\label{563614}}

LaTeX (pronounced~\emph{lay-tech} or~\emph{lah-tech}) is a
\href{https://en.wikipedia.org/wiki/Turing_completeness}{Turing-complete}
markup language and typesetting framework used most often in the
physical and mathematical sciences \cite{texentry}. LaTeX has history
going back to 1985 -- and TeX, the progenitor of LaTeX, goes back to
1978 when it was introduced by computer scientist and mathematician
Donald Knuth.

\par\null

LaTeX is first and foremost designed for typesetting mathematical
notation on the printed page. LaTeX gives increased control for
typesetting, enabling far stricter control of elements on a page -- from
tables to specialized mathematical notation and so forth. LaTeX is
widely used in the physical sciences and to this day LaTeX is used for
typesetting journals, textbooks, and other structured texts.

to Write Mathematical Equations, Expressions, and Symbols with LaTeX}
\end{quote}

In recent years, several
\href{https://www.authorea.com/users/87589/articles/167329-latex-software}{LaTeX
software}~options have introduced online-only versions that bring the
traditional LaTeX compiler to the cloud. These online LaTeX solutions
come with advantages and disadvantages, however LaTeX on its own remains
problematic for producing web-native content as it's extremely difficult
to determine how text will look online if typeset using LaTeX.

\section*{Advantages of online LaTeX}

{\label{918532}}

Online LaTeX compilers remove the need for collaborators to install
local instances. This advantage cannot be overstated -- it removes a big
headache related to local compiling of LaTeX code. In addition, online
LaTeX compilers provide centralized package support, which means that
every collaborator is able to work with the same support for LaTeX
packages, eliminating issues that arise from having different local
installations of LaTeX.

\par\null

Since Authorea supports LaTeX, it's simple to add some to a document:
\begin{equation}
F\left(x\right)=\int_a^xf\left(t\right)dt
\end{equation}

\par\null

\section*{Traditionally, LaTeX is for the printed page -- not the
web}

{\label{616959}}

Online LaTeX is still LaTeX -- primarily destined for the print-based
world. Whether the compiler is local or online, LaTeX is still weirdly
out of place in a web-first research world. Getting LaTeX to look good
on the web is a long-lasting problem! ~

\par\null

\section*{Online LaTeX options}

{\label{825440}}

The two pure online LaTeX compilers out there are
\href{http://www.sharelatex.com}{ShareLaTeX}~and
\href{http://www.overleaf.com}{Overleaf}. The two options are fairly
interchangeable with some minor differences. Authorea is an
\href{https://www.authorea.com/users/3/articles/108532-how-is-authorea-different-from-sharelatex-and-overleaf}{alternative
to ShareLaTeX and Overleaf}~that is intended for use by all researchers
rather than just LaTeX writers. Authorea is the only web-based writing
environment for researchers that supports LaTeX, markdown, and richtext
in the same place -- and renders all typesetting to beautiful HTML5 in
the browser.~
