Contour - Segment Anything

Contour is a native macOS segmentation workstation built for ML researchers, computer-vision engineers, annotation teams, and post-production artists who need clean, prompt-driven instance masks — in bulk, on their own machine, without sending a single pixel to the cloud. Drop a folder of images into a Collection, type a prompt or draw a box, tune the threshold, and export mask PNGs, transparent cutouts, COCO JSON, or YOLO TXT straight from the Mac.
