We present the Worldline Monte Carlo method, a direct numerical evaluation of quantum mechanical path integrals. We prove the validity of the method by simulating the QED effective action and we illustrate some improvements to the sampling trajectories with a quantum mechanical system. Finally, we discuss a numerical implementation for the evaluation of Grassmann path integrals with the aim of incorporating spin within the Worldline Monte Carlo formalism.
