Targeted at users troubled by the high cost of Adobe Photoshop or the unfamiliar interface of GIMP. It faithfully reproduces Photoshop's compositing and post-processing workflows, enabling precise pixel-level editing with familiar shortcuts and tools.

It supports advanced features such as layer masks, clipping masks, and various adjustment layers. In addition to retouching tools like Content-Aware Fill and Spot Healing Brush, complex compositing tasks can be handled efficiently through non-destructive transformations and snapping features.

It runs on macOS 26 or later, and you can open the Xcode project to directly modify the source code or add features. Adopting the MIT license, there are no restrictions on commercial use or custom builds.
