Abstract: We present the AM$^3$ (``Astrophysical Multi-Messenger Modeling'') software, which has been successfully used in the past to simulate the multi-messenger emission, including neutrinos, from active galactic nuclei, including the blazar sub-class, gamma-ray bursts, and tidal disruption events. AM$^3$ is a documented state-of-the-art open source software that efficiently solves the coupled integro-differential equations for the spectral and temporal evolution of the relevant particle densities (photons, electrons, positrons, protons, neutrons, pions, muons, and neutrinos). AM$^3$ includes all relevant non-thermal processes (synchrotron, inverse Compton scattering, photon-photon annihilation, proton-proton and proton-photon pion production, and photo-pair production). The software self-consistently calculates the full cascade of primary and secondary particles, outperforming simple test-particle approaches, and allows for non-linear feedback and predictions in the time domain. It also allows to track separately the contributions of different radiative processes to the overall photon and neutrino spectra, including the different hadronic interaction channels. With its efficient hybrid solver combining analytical and numerical techniques, AM$^3$ combines efficiency and accuracy at a user-adjustable level. We describe the technical details of the numerical framework and present examples of applications to various astrophysical environments.
