Crosy is a browser-based editor for cross-stitch charts. It converts a photo to a limited-color stitch grid, or starts from a blank design. Users can adjust chart dimensions and thread colors, edit individual stitches and backstitch, and mark stitching progress. Projects save on the current device, with optional account cloud sync within plan limits. Preview, standard editing and progress tracking are free. A 30-credit pattern unlock enables chart and project downloads in PDF, image, SVG and exchange formats. Credit packs and optional Pro subscriptions are available. Crosy uses image conversion and direct grid editing; it is not an AI image generator.
