Zerro: Point at Your Live App, Speak, and Watch Claude Code Edit It Instantly

Zerro is a Mac app that replaces keyboard-driven prompting with pointing and speaking. You frame any part of your screen with the cursor, describe the change out loud (e.g., "copy this theme and these colors," "add this scrolling ticker animation"), and the command is handed to Claude Code or Codex/Cursor running on your project. The tool edits real files, your dev server hot-reloads, and the change appears live.

How It Works

• Pointing resolution: Put your cursor on a UI element (e.g., a nav bar), say "this one," and Zerro identifies which element you meant — not just a screenshot crop.
• Live capture of motion: Unlike pasting a static screenshot into Claude, Zerro captures live animations — scrolling tickers, orbitals, animated backgrounds — so you can say "I want that" about moving content.
• Checkpoint safety: Every run snapshots your project state before executing, making any change one-click revertible.

In the demo, the creator built a landing page from a blank starter hands-free by pointing at reference sites and giving verbal instructions like "Use this orbital, and swap the nav bar for this one" or "Make the background this animated one, recolored to match."

Compatibility

Zerro works with Claude Code by default but also supports Codex and Cursor. It runs on your own API login — no intermediate server shares your credentials.
