Native macOS studio to create, translate and publish App Store screenshots
One click grabs a screenshot from the Xcode Simulator Device Hub and imports it as a new artboard, so you can iterate on designs as fast as you can build.
Link a folder of images — for example a Fastlane or UI-test output directory — and your artboards update automatically whenever new localizations land.
Place screenshots inside high-resolution 3D devices, rotate them to any angle and pan across artboards for panoramic backgrounds, all rendered smoothly up to 120fps.
Localize screenshots and app metadata into the full set of App Store Connect languages from one artboard, with designs staying in sync across languages.
A native, fast AI chat client for Mac, iPad, and iPhone
The keyboard extension brings AI text generation into Messages, Notes, Mail, and any other app on your device, so you never have to switch contexts to ask a question.
Talk to your assistant hands-free and hear spoken replies, with Siri Shortcuts for triggering a chat without opening the app.
Switch between different AI models and providers for different tasks, and keep a curated prompt library ready for recurring needs.
Generate images from text prompts, discuss photos inside a conversation, and translate text between languages without leaving the chat.
