Few months ago I've shared a new kind of markdown editor that we (a team of three from the Czech Republic) have been working on (HN post: https://news.ycombinator.com/item?id=46144801). What resonated with folks the most was Kraa's unique ‘live-typing’ chat feature. We have now acted on this feedback, improved the chat features, and made Kraa Trees. Trees allow anyone to create a light-weight community. It would be a stretch to call it an alternative to Discord, yet, but we hope that the frictionless nature of Trees will make them useful for small groups that want something simpler, more immediate, and less cluttered. With the live-typing being one of the key differentiating features.
You can create your own community/rooms by selecting "Tree of leaves" in the New leaf button dropdown.
You don't need an account to try Kraa nor Kraa Trees. We would love to know what you think!
