I am looking to make a website for writing books. Rather obviously, the most crucial part of this is its editor. I plan for people to be able to upload
.scriv, LaTeX, and Markdown files, but for others who may not be familiar with these or want to use a different way, I need a fully online editor.
Some of the things I have researched about so far, good though they are, aren't suitable for the long format that books require. Even if I only allowed to edit a chapter at a time, it would be rather preposterous to use something like Froala or CKEditor. Does anyone know of a good one? I've also investiagated Ace, but it's immediately evident that it's more code-oriented. Perhaps it would be good for people looking to write in LaTeX online, but is not suitable for my purposes. If anyone requires a detailed list of requirements, please say so in the comments. As an aside, free would be absolutely wonderful.
Thanks in advance!
