Tiles a live, customizable watermark across every desktop — text, icons, and date/user tokens

DownloadSourceView All Apps

Ghostmark renders a live watermark tiled across every connected display, sitting on the desktop behind your app windows. Customize the text and icon, rotation, layout mode, spacing, colors, stroke, and shadow, and drop in {date}, {time}, {datetime}, {user}, or {host} tokens that stay current on their own. Three window levels let you choose whether it hides behind windows, floats above them, or sits in between. Multi-monitor aware — displays are tracked by hardware ID, so rearranging screens rebuilds the tiling correctly.
