Target elements, not screenshots.

Loupe is a macOS accessibility inspector that generates AI-agent-ready output. I built this for myself to speed up Mac app development with Claude Code. Hopefully you find it useful too.

https://smughead.github.io/Loupe/

• Inspect any UI element in any Mac app
• Annotate what you want changed
• Copy structured, agent-readable output
• Paste into Claude Code, Cursor, Codex — and watch them build

Hover — Point at any element in any app and see accessibility info in real-time.

Annotate — Click an element, describe the change you want in plain English.

Copy — Hit the copy button to get structured output with element roles, hierarchy paths, and search patterns.

Build — Paste into your AI assistant. It knows exactly which element to target — no screenshots, no guessing.
