SuperCard allows users to create personal applications that have the look and feel of conventional Mac programs, including full color paint and draw, multiple window types (including resizable windows and dialog boxes), cards of any size, multiple files (stacks) open at the same time, custom menus and the ability to assign “button” properties to any object, including paint and draw graphics.
The program uses the SuperTalk scripting language, an extension of HyperTalk, that includes new commands for SuperCard’s additional graphics functions for animation and for managing windows and menus.
SuperCard is HyperCard compatible and will translate all stacks, scripts, XCMDs and XFCNs. Users can save their SuperCard applications as stand-alone applications that don’t require SuperCard to run and that can be distributed without a license fee.

SuperCard is a HyperCard-like software development kit, with more features. For instance, it came already with color (HyperCard did not) and it had a full GUI toolkit. SuperCard has another major improvement over HyperCard: it can make applications out of its card stacks so that they become standalone and thus can be run without SuperCard on other computers.
SuperCard uses its own scripting (programming) language called SuperTalk, somewhat similar to what HyperCard was using (HyperTalk).
