How Does It Work

With Markly, creating design specs is simple and visual

No manual measuring any more. After imported your design from Adobe Photoshop or Sketch (product by Bohemian Coding) into Markly, you can add specification marks by simple clicking and dragging. Coordinate, dimensions, distance or fonts, no matter what and where you want. When you finished, you can export the canvas as PNG image by clicking one button.

Zero configuration, the appearance styles are synced globally

Without Markly, you have to spend time to apply styles to each individual specification element. Even you can create a list of styles in your layer settings by following some steps, soon you will find it hard to maintain.

But with Markly, no configuration needed since Markly will do this job for you. You wan to change the line colors, line arrow styles, or label styles? No problem. You want to toggle different unit displays for your asset? No problem.

Specs updated automatically when your design was modified

If you create specifications directly on your layers, once you modified your design, you have to modify the marks according to your changes one by one.

However, you don't have to do this in Markly. Since the spec data are organized and saved independently, whenever you imported your design into our app, the specifications will be self-updated automatically. No extra adjustments needed.
