Description

Ship App Store screenshots without the busywork. ButterKit is a Mac-native studio for developers and designers to capture straight from Xcode Simulator, compose in a realtime 3D renderer with photorealistic devices, translate, and batch-export. It’s fast, precise, and private - built on Metal with no accounts or ads. Apple M1 or newer is recommended for best performance. KEY FEATURES • App Store Screenshot Design Studio: pro typography, gradient tools, and precise 3D device controls (style, bezel, rotation, scale). • Professional Templates: designer-built layouts make screenshots look polished in minutes. • Simulator Capture: pull directly from Xcode Simulator and keep pixel-perfect device geometry and safe areas. • Automatic Translations: use built-in translations for 20+ languages, or bring your own OpenAI API key to translate to all 39 supported ASC languages. • Batch Export: with correct sizes, locale mapping, and consistent file naming for faster App Store Connect uploads • Built for Real Workflows: infinite canvas, keyboard shortcuts, undo/redo, file saving, custom fonts, gradients, and style presets. • Mac-native, Metal-accelerated: buttery-smooth editing with a realtime 3D renderer and lifelike iPhone, iPad, and Mac device frames. • Private by Design: all core features run on-device. Optionally use your own API keys for additional translation options (Pro feature) BUILT FOR DEVS & DESIGNERS ButterKit streamlines the full pipeline from capture, edit, translate, and export - so you spend time refining your product, not wrangling artboards.
