Professionally typeset and formatted papers in one click

For many LaTeX users, a major benefit of LaTeX is the fact that it produces beautiful, professionally typeset documents (PDFs). Overleaf and ShareLaTeX accomplish this in the most traditional way, way:  you write LaTeX starting with a template and then compile a PDF that uses that template styling. Authorea separates format from content. All content created does not have a specific output format. At any point in time, you can export a version of your document (PDF, Word, etc) formatted in the style of your choice (e.g. Nature, Science, APA style, Biomed central, and hundreds of other styles). Why is this important? If you submit a paper to Nature and get rejected, you don’t have to spend a full day reformatting your paper and citations according to, say, Science style. Authorea does it for you, in one click.
