Legal and compliance (L&C) workflows are notoriously large sources of friction and frustration when conducted manually. To turn these workflows into scalable systems to provide abundant L&C advice to humans and other AI systems, we developed Legal Engineering, a discipline marrying AI and legal expertise. Lawyers without programming experience become cyborgs and build interpretable, domainspecific legal AI systems. Legal Engineering was born out of the recognition that an integration of different language types – legal and programming – was required to push the frontier of providing abundant reliable L&C advice.
