Procreate offers QuickShape, a built-in drawing tool that automatically snaps hand-drawn lines and rough shapes into geometrically perfect forms such as circles, squares, and triangles. The feature is available to all users as a default part of the app.

QuickShape activates when a user draws a shape and holds their Apple Pencil or finger on the canvas; the app then snaps the stroke into a clean geometric shape. Procreate's official handbook describes QuickShape as snapping strokes into perfect lines, arcs, ellipses, triangles, and quadrilaterals. One third-party tutorial source describes the feature as using a machine learning algorithm to classify input strokes, though Procreate's own documentation does not use this language, and the technical mechanism has not been confirmed as machine learning by a primary source. All processing occurs on-device; Procreate's privacy policy confirms the app does not connect to external servers.
