Linearity offers an AI-powered Auto Trace feature in Linearity Curve that converts raster images — such as scanned sketches, photos, or digital illustrations — into editable vector graphics in seconds. The tool automatically selects the best tracing mode for the image type and outputs scalable vector shapes.

Auto Trace uses a custom algorithm and a CoreML machine-learning model to analyze an input raster image and determine whether to apply Sketch, Photo, Illustration, or Basic Shapes mode. The Illustration Mode uses a neural network trained on thousands of manually traced images. The tool produces editable vector paths and shapes with adjustable parameters for detail level, color precision, and gradient smoothness. It was first launched in 2019 as part of Vectornator and received a major upgrade with new modes including the Illustration Mode (released in app version 4.9.0) and Basic Shapes.
