6- Authorea is not owned by a publisher. Depending on your views, you may see this point as an advantage or disadvantage. Overleaf is owned by Macmillan Publishing (i.e. Springer/Nature). Authorea is a private company with a social mission to make science more transparent, reproducible and modern. We are firm believers of the Open Access and Open Science movements and we strongly criticize the current oligopoly of academic publishing (this summarizes everything that we find wrong with the academic publishing industry, in one tweet).
