Show HN: Arky – Visual 2D Markdown editor (access codes below)

https://app.arky.so
12•masonkim25•3mo ago
Hey HN! Arky is a markdown editor with a twist — instead of writing in a linear doc, you work on a 2D canvas where you can:

• Place ideas anywhere spatially

• Organize them into hierarchy with drag & drop

• See the full document structure at a glance

• AI writes contextually — drag & drop responses anywhere on canvas

More info: https://arky.so/

Try it: https://app.arky.so/ (Access codes are in the comment below!)

Quick demo(60s): https://youtu.be/Nxsr5Ag2vEM?si=g6nKheRWWNuaLTe8

Would love to hear your thoughts!

Here are 10 access codes to try it out:

f02f24, 25c2ff, ebf35f, 5411cf, f22385, 84bcbb, cbd3dd, 3c1091, 7cbfd3, 1baf8d

If these run out, comment below for more! I'll send you one.

masonkim25•3mo ago
You might use Arky for:

• Brainstorming

• Structuring strategy docs

• Organizing complex ideas

Try it for research drafts or organizing messy thoughts!

I do actually quite like snapping texts together like lego, it is very satisfying, multi-user live editing would make this a great addition for meetings
masonkim25•3mo ago
Thanks! Glad you like the Lego-style snapping — multi-user live editing is definitely on our roadmap.
hereme888•3mo ago
Difficult market to penetrate. The niche seems so saturated already. Good luck.
masonkim25•3mo ago
Appreciate it! I agree — it’s a crowded space. And yeah, building a new kind of editor is definitely a challenge.

But I genuinely believe there’s room for something different — a tool that makes collaborating WITH AI feel natural. Most interfaces we use today were designed before AI became part of the workflow.
