We are a team of three building a markdown editor. We have shown our web app here a few months ago (https://news.ycombinator.com/item?id=46144801) and got some great feedback that prompted the creation of a feature we want to show today – Kraa Trees.

Trees are a collection of leafs (documents) that can contain anything from regular collaborative documents to real-real-time chats (try it out to see the real-real-time aspect of it).

With this, anyone can now create a simple discord-like community (like in the main linked example), but there are other possible use cases, like - chapters in a book, collection of related documents, ...

You don't need an account to try this out (or to use Kraa in general). We would love to know what you think!
