The Stack That Changes
How AI Gets Built

Jac is the world's first AI-native full-stack programming language, born at the University of Michigan and backed by NVIDIA and NSF. It supersets Python and JavaScript into one unified language where backend, frontend, and AI live in a single file. JacHacks is your chance to build with it before the rest of the world catches on.
