Until just a few years ago, only human eyes monitored the entire night sky. We changed that with our​``All-Sky Automated Survey for Supernovae'' (ASAS-SN), which automatically surveys the entire visible sky every night, for the first time in human history. ASAS-SN is discovering large numbers of bright transients, including supernovae, quasar flares, tidal disruption events, Galactic novae, and variable stars, that in turn trigger additional observations across the electromagnetic spectrum and beyond.

I will discuss some of the most interesting ASAS-SN discoveries, as well as the various ways in which we make the data public. The scientific value and public utility of ASAS-SN data are growing rapidly, and I will discuss the plans for that to continue and expand in the future.
