5- Authorea is natively built on Git. This has two major advantages: 1) All changes made to Authorea documents are tracked by Git i.e. the most robust version control system around. No more need to tracking changes in Word. Version history of any document is nicely integrated within the document itself. 2) Since every document in Authorea is a Git repository, you can include more than just text and images: data, code, videos, data visualizations, notebooks, workflows. Authorea is a data-driven media-rich platform.
