Loupe

Loupe is a macOS accessibility inspector that lets developers examine any UI element in any Mac application and produce structured data suitable for AI agents. By hovering over an element, it displays real‑time accessibility information such as role, hierarchy path and searchable patterns. Users can annotate a selected element with a plain‑English description of the desired change, then copy the resulting output, which combines the element’s metadata with the annotation in a machine‑readable format.

The generated output is intended for use with AI coding assistants like Claude Code, Cursor or Codex, allowing those tools to target specific UI components without relying on screenshots or visual inference. This workflow aims to streamline the process of adapting or extending Mac apps through AI‑driven code generation.

Loupe runs on macOS 14.0+ (Sonoma) and requires standard accessibility permissions. It is distributed as an open‑source MIT‑licensed project, available as a prebuilt DMG or via source code that can be built with Xcode.
