App Store Preview is here

2025 September 25

App Store Preview functionality is rolling out today. Shout-out to everyone who requested this!

• Introducing App Store Preview: see how your design and layouts will look on the App Store before you export (works with iPhone for now, more devices coming soon)
• Improved Export Engine performance and settings
• Bug fixes: fixed an issue where selecting “System” theme wouldn’t completely swap theme (thanks Dave!)
• Update from ButterKit → Check for Updates (Mac App Store version will rollout pending approval!)

Added support for markdown

2025 September 16

Thanks to a /r/butterkit reddit user request! You can now use markdown when editing text to emphasize certain words.

• Bold and italic markdown is supported and renders instantly onto your artboards. Hyperlinks and headings are ignored.
• Improved text editing UI when using markdown
• Markdown generally translates well using both the onboard and OpenAI translation engines, but remember to check your translations when publishing
• The canvas camera now retains user zoom level when selecting other artboards, and auto-zooms when selecting multiple to automatically frame the selection for convenience
• More details available in the docs

Improved zoom and pan behavior

Thanks to reddit (/r/butterkit) users! This release introduces smoother, more precise panning on the canvas and adds helpful ⌘+ and ⌘- keyboard shortcuts to quickly zoom in and out (in addition to the usual pinch to zoom). Also improved the translation language selection UI.

Added OpenAI support (bring-your-own API key)

Thanks to reddit (/r/butterkit) users! This release reduces the panning speed on the canvas and adds helpful ⌘+ and ⌘- keyboard shortcuts to quickly zoom in and out (in addition to the usual pinch to zoom). Also improved the translation language selection UI.
