Authorea offers a Standard editor and a Beta editor (Beta launched in January 2017). The two editors function in a fundamental different way so if you start one article with the Beta editor, it will stay in Beta, and viceversa.
Authorea Beta.Most users will want to use our new editor, Authorea Beta. It is easy to use, it has the look and feel of most modern collaborative editors, and at the same time a wide range of markup languages and scientific integrations, including the most popular citation management, graphing, and visualization plugins. Click here to see how Authorea Beta compares to our Standard editor
Authorea Standard.
If you are a power LaTeX or Markdown user, you will probably prefer working with a non-WYSIWYG editor. In that case, we recommend the Standard editor.
