What is analog in Tex?
There is a number of packages that you could use: todonotes and changebar are two of them; a little example:
\documentclass{article}
\usepackage{todonotes}
\usepackage{changebar}
\usepackage{lipsum}
\begin{document}
\lipsum[2]
\begin{changebar}
\lipsum[2]
\end{changebar}
\lipsum*[2] text text
\todo[prepend]{A very long and tedious
note that cannot be on one line in the list of todos.}.
\lipsum[2]
\end{document}

For some external tools, you could see "Track changes" in LaTeX
