A quick search came up with Draft (https://draftin.com/) and Reeday Book Editor (https://reedsy.com/write-a-book). I haven't used these myself, so take a look around. Source: over 1 year ago
Similarly, cloud based Markdown editors such as HedgeDoc, StackEdit, HackMD and Draft among others are not great choices for those who don't have Markdown experience, plus are a bit more barebones than desired for project management. The same applies for LaTex collaboration software like Overleaf. - Source: dev.to / over 2 years ago
