Our verdict on RectLabel
RectLabel is an offline macOS application for annotating images used in object detection and segmentation workflows. It suits individuals and teams working on a Mac who need more than basic bounding boxes, with support for rotated boxes, polygons, cubic Bézier curves, lines, points, pixels, image labels, keypoints, and skeletons. The tool also covers video-to-frame conversion, image augmentation, slicing, and dataset export for common machine-learning formats.
Pricing is straightforward across three plans. RectLabel Monthly costs $2.99 per month, while RectLabel Annual costs $9.99 per year; both provide the standard RectLabel subscription. RectLabel Pro costs $19.99 as a one-time payment and includes no in-app purchases or network connections. The standard trial is untimed, but continued use requires a purchase. For buyers prioritizing a low annual cost, the annual plan is the clearest entry point; Pro is the relevant option for those who prefer a one-time payment.
The standout capability is the breadth of annotation and model-assisted labeling. Segment Anything, Cellpose, tracking models, and Core ML models can support labeling, while automatic text recognition handles lines and words. Exports include YOLO, COCO JSON, Create ML JSON, DOTA, CSV, mask images, and classification folders, which gives the application useful format coverage for computer-vision projects. RectLabel is a strong fit for Mac-based annotation with advanced tools and offline operation. Buyers needing collaboration, API access, integrations, or a non-macOS platform should choose an alternative.
