The tool can interactively edit corresponding geometry in real time using cutter objects. These cutter objects can also be instanced or arranged in arrays or combined to create patterns.

SpeedCut is currently available free here on Gumroad. The developer has so far tested the Python tool under Maya 2018.5, but Maya 2019 is also said to be supported.
