Real-Real-Time Chat
Hi HN! 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 ‘real-real-time’ chat feature. We have now acted on this feedback, improved the chat features, and made what we call Kraa Trees. Trees allow anyone to create a light-weight community / chat channels.

In plain words
Real-Real-Time Chat is a markdown editor with lightweight community and chat channels called Kraa Trees. Built by a three-person team from the Czech Republic, it emphasizes real-time communication features, particularly live-typing visibility.

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!

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
