The software is Vanilla JS only - no frameworks, CSS, images, svg, or video used or required. It's totally pure JS. It's for commercial, social media, and educational use. Creative web developers and designers have a new simple to use tool.

Users are inevitably drawn to the hand that's writing. One line of code loads the plugin then any number of calls to it causes writing to happen when required. Typically the writing will occur in an element (a div, say) or a chosen area of the window. The software auto deals with font size and spacing.
