This is a minimally intrusive package that changes the default overlay behavior of the tikz commands \draw, \fill, \filldraw, \clip, and \node within the beamer document class to the \onslide behavior. As a consequence, the bounding box of any tikzpicture environment is fixed for the entire frame - hence the portmanteau fikz - which prevents images from "jumping around" from slide to slide. In any other document class, overlay specifications of those tikz commands are ignored, allowing the same source code of a tikzpicture with overlay specifications to be used both in a research presentation and the paper, or in lecture slides and the assignments.
The package provides no commands. The default behavior is changed by simply loading the package.
