Meshmerize
Needlepoint pattern designer
Design needlepoint patterns from scratch or import a photo and let the app convert it into a stitch-ready pattern. Matches colors to real thread brands using perceptual color science and GPU-accelerated processing.
Features
Professional pattern tools backed by real color science.
Drawing Tools
Pencil, eraser, fill, eyedropper, and magic fill with adjustable brush sizes.
Image Import
Import photos as underlays or auto-detect grid patterns with rotation correction.
Thread Matching
Match colors to DMC, Anchor, Cosmo, and Sullivans threads using perceptual color science.
GPU Accelerated
Metal compute shaders for K-means clustering, color sampling, and large canvas rendering.
Custom Grids
Configurable rows, columns, and mesh count with zoom, pan, and scroll support.
Auto Processing
K-means++ color quantization reduces images to 2–64 colors in CIE L*a*b* space.
Pattern Export
Export finished patterns with stitch counts and thread codes for production.
Native macOS
Built with SwiftUI and Metal. Document-based app with full keyboard shortcuts.
