SlimSnap

Free Mac app that turns a screenshot into structured JSON (text, elements, colors, boxes) for AI agents.

DesktopEmergingfreeglobal

SlimSnap is a free Mac app that captures a screen region and outputs structured JSON — text, elements, colors, and bounding boxes, plus drawn annotations — instead of an image. It's built so terminal AI coding agents that can't read images, or misread flat screenshots, can act on the exact element indicated. OCR runs on-device and the JSON schema is MIT-licensed.
