It's trying to be universal for any writing need, so purposefully not having a specific 'main' use case, but suitable for many – personal notes, blog posts, colab docs, chat, ...

https://kraa.io/about has some more information about the product itself.

Kraa Trees can be used for other non-chat use cases, like listing out chapters of a book or putting relevant documents together. Example: https://kraa.io/kraa/demos

Hi HN!

Trees allow anyone to create a light-weight community / chat channels. 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!

For a loosely similar 'benchmark', I recently tried to test major LLMs on my coding game (models write code controlling their units in a 1v1 RTS) - https://yare.io/ai-arena

This seems to be comparing apples to oranges. The intent of the users inside ChatGPT and on the website would be vastly different. Comparing them doesn't make much sense sans other variables (= better understanding the intent)

For a European alternative to Google Docs / Notion, we made https://kraa.io/about that might work for you if all you need is a simple editor with collab features.

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 ‘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.

I'm guilty of this as well. https://kraa.io/about has some fade-in animation for the intro text – driven by wanting the initial impression to be focused/minimal and 'unravel' as you go. I take it that most HN folks would vastly prefer to NOT have this?

An old article, but imo still relevant and interesting. My favorite part:

> Life and work would be so easy if a lack of quality could be explained in a sentence, and fixed with a better technique. If an artifact lacks quality, it is not just one aspect that needs improvement and then it’s all good. Quality is not just the method, just the form, or just the content. The lack of quality doesn’t cumulate in a spot, it is fundamental...

Show HN: Create your own online community

levmiseri — Tue, 17 Mar 2026 07:04:47 +0000

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!

That’s true, I’m trying to figure out a better testing environment with a feedback loop.

I did try letting the models iterate on the bot code based on a summary of an end-of-game ‘report’, but that showed only marginal improvements vs. zero-shot

I’m not sure honestly. It could be some combination of bad spatial reasoning of the LLMs and lack of any training data for this specific challenge.

You can see replays for all of the matches if you hover over the cells in the table.

Show HN: 1v1 coding game that LLMs struggle with

levmiseri — Fri, 06 Mar 2026 06:47:29 +0000

This is a game I wish I had as a kid learning programming. The concept of it is fairly similar to other coding games like Screeps, but instead of a complex world with intricate mechanics, Yare is a lot more minimal and approachable with quick 1v1 <3 min matches.

It's purely a passion project with no monetization aspirations. And it's open source: https://github.com/riesvile/yare

The first version 'launched' several years ago and I got some good feedback here: https://news.ycombinator.com/item?id=27365961 that I iterated on.

The latest overhaul is a result of simplifying everything while still keeping the skill ceiling high. And at least the LLMs seem to struggle with this challenge for now (I run a small tournament between major models - results and details here: https://yare.io/ai-arena

I'd love to hear your thoughts

A deceptively simple game of 9 vs. 9 cats. Your actions are limited to moving and shooting, but 'how' you move your units and when or which cat you shoot can be difficult to decide.

You can play against the prepared bots, or against other 'human' players in real-time matches.

Stellar work. Combination of good design and good engineering really shines here.

This must have taken ages to produce. Thank you for it!
