Mark Man

The tool provides a visual interface for annotating and measuring design drafts. Users can place length markers, coordinate points, rectangles, color swatches, and text notes directly on images. It supports automatic length calculation, drag‑to‑delete annotations, and custom styling of marker color, size, and color‑value format via a right‑click menu.

It works with a range of image formats, including PSD (saved with maximum compatibility), PNG, BMP, and JPG, and can handle Retina @2x files by scaling them down 50 % to keep measurements accurate. The application monitors the source file and reloads it automatically when the design is modified, keeping annotations synchronized with the latest version.

Available for Windows and macOS, the software offers a free basic tier and a paid professional tier that unlocks additional features. It is targeted at designers and online‑store sellers who need quick, precise markup of product images or mockups.
