AI-Powered

Your co-pilot
lives in the editor

Ask kAIxU to write, refactor, explain, or fix your code. The AI reads your entire workspace before responding, and applies changes with diff preview.

What can it do?

  • Write new components, functions or entire files from a description
  • Refactor messy code with a single prompt
  • Explain what any function or block does in plain English
  • Fix bugs you describe — including ones in the Problems panel
  • File-aware: reads your open workspace before every answer
  • Diff safety: preview every change before it's written
  • AI-generated problems surface in the Problems panel as "kAIxU" items

Add a dark mode toggle to the nav that persists in localStorage
✦
kAIxU
Sure — I'll add a button to nav and wire it to localStorage:
<nav class="nav">
+ <button id="theme-toggle" onclick="toggleDark()">🌙</button>
</nav>
+ function toggleDark() {
+ document.body.classList.toggle('dark');
+ localStorage.setItem('theme',
+ document.body.classList.contains('dark') ? 'dark' : 'light');
+ }
Keyboard-first

Every action.
One keystroke.
