FluidUse
A Swift package for local computer use on Apple Silicon that reads a form through the Accessibility API and asks a small on-device model what belongs in each field. Its Laya integration runs FluidInference's Core ML port of Laya on the Neural Engine at 3.7 ms per decision on an M5 Pro, about seven times faster than the upstream GPU figure.
