Collects no user data and operates without accounts, ensuring complete data ownership and avoiding lock-in, as stated in the README.
Uses native UI controls and behaviors like force-touch word lookup and inline predictions, providing a seamless experience that feels at home on Mac.
Built on CodeMirror 6, it efficiently handles large files up to 10 MB, offering faster and more complex editing than many macOS editors.
With a 4 MB installer, it's minimal yet customizable via CSS, JavaScript, and official extensions for preview, theming, and AI writing, as detailed in the features.
Limited to macOS 15.0+ with separate builds for older versions, making it unsuitable for cross-platform workflows or users on other operating systems.
Described as 'feature-poor' in the wiki, it lacks advanced built-in tools like rich text editing or comprehensive plugin ecosystems, relying on extensions for basic functionality.
Essential features such as preview pane and custom themes require installing separate extensions (e.g., MarkEdit-preview), adding setup complexity for users wanting an all-in-one solution.
