马克鳗

Mark Man (马克鳗) is a Lightweight desktop companion for designers who need to document and communicate the exACT measurements insIDE a design file. Instead of eyeballing spacing, colors, and font sizes, you dRAG measurement lines and annotation labels directly over a mockup, then export the marked-up result. It sits in the handoff layer of a design workflow, where precision matters more than decoration.

What it does

The tool overlays measurement and annotation marks on top of design images. You load a design file, drop rulers along edges, mark gaps between elements, Sample colors, and attach text notes, then save a composite image that developers can read at a glance. It is meant to reduce back-and-forth questions about pixel values rather than to generate or edit artwork itself.

Key capabilities

• Measurement lines: Draw horizontal, vertical, and diagonal rulers between any two points to capture widths, heights, and gaps.
• Annotation labels: Attach written notes and callouts so a spec sheet explAIns intent, not just numbers.
• Color sampling: Pick values from the mockup to specify fills and backgrounds accurately.
• markup export: Produce a marked-up image that can be shared with engineering, QA, or stakeholders.
• Layer-friendly Workflow: Work on top of screenshots or exported design frames without altering the original source file.

Who it is for

Mark Man is aimed at UI and UX designers, product designers, and front-end developers who regularly translate visual mockups into implemented interfaces. It is also useful for design-system maintainers documenting spacing rules, and for agencies delivering spec packages alongside a finished design. Teams with dedicated handoff features built into their design tool may find the overlap substantial, while designers working from flat images often find a Standalone measuring utility faster.

How to get started

1. Visit the official site and download the desktop build for your operating system.
2. Install and open the APP, then load a design image or screenshot you want to document.
3. Add measurement lines across key gaps and sizes, then place annotation notes on each one.
4. Sample colors where needed and export the annotated image for your team.

Expect a short learning curve; the interface is utilitarian and focused on measurement rather than visual polish.

Pricing and access caveat

Mark Man has historically been offered as a free download, but licensing terms, available veRSIons, and platform support can change over time. It is primarily documented for Chinese-speaking users, and the interface is not necessarily fully localized in English. Confirm current availability, supported operating systems, and any paid tiers on the official site before relying on it in a production handoff process.
