Description
You open a long markdown document on your iPhone. You need section four. You scroll. And scroll. And scroll.
Your current editor -- the one that costs $19.99, or charges you every month -- doesn't have a document outline on iPhone. It never has. You've been asking for years.
Krux has it. Day one.
Tap the outline panel and jump to any heading in your document instantly. On iPhone. On iPad. On Mac. It works the way it should have always worked.

WRITE EVERYWHERE
Krux is a native markdown editor built for every Apple device you own. iPhone, iPad, Mac, Apple Watch. Your documents sync through iCloud Drive as standard .md files -- the same files you open in VS Code, BBEdit, or any editor you choose.
Dictate a note on your Apple Watch while your phone is in your bag. It's in your Files app by the time you sit down.

THE LANGUAGE OF AI, NATIVELY
Claude Code, ChatGPT, and GitHub Copilot all write in markdown. Krux is where that output lives on your iPhone -- rendered cleanly, navigated with the outline, stored as plain files that feed right back into your workflow.
Markdown is the language of AI. Krux is its native home.
