Web-based markdown editor that can handle notes, colab documents, todos, long stories, as well as chats or communities.

I know that there are already way too many markdown editors out there, but I think Kraa still offers something unique in this space (combination of minimal UI, plentiful features and some unique stuff like real-real-time chat).

Example of how easy it is to create a 'community' on Kraa: https://kraa.io/kraa/trees

Also - no AI integrations whatsoever.
