I'm looking for a real-time in-browser collaborative text editor (like Etherpad), either WYSIWYG or Markdown, that would have the possibility to easily add links that would be clickable and point to new pads that can be created and edited when clicked, essentially like a wiki. It seems to me like this would be a natural extension of Etherpad to work on larger documents by splitting them into separate pages, while keeping the real-time collaborative aspect of Etherpad. Does such a software exist?
I'd be looking for a free/open source self-hostable solution, ideally with support for zero-knowledge (the server does not know what it is hosting) like Zerobin and Cryptpad. Any ideas?
