How it works

Four steps. Zero cloud calls.

From screen capture to actionable bug report — everything runs locally on your Mac using Apple's native frameworks.

01

Capture

Select a region or entire window via ScreenCaptureKit. Grab exactly what you need.

02

Detect

Apple Vision identifies UI elements, text, frames, and overlapping components automatically.

03

Reason

On-device AI via Apple Intelligence analyses layout issues and classifies severity.

04

Report

A structured Markdown bug report with severity ratings, ready to paste or export.

Features

Built for developers who care
about pixel-perfect UI.

Native macOS app, no Electron, no cloud dependencies. Just fast, private, intelligent UI analysis.

100% On-Device

No cloud calls, no telemetry. Your screen content never leaves your Mac. Period.
