This paper reviews our current understanding of low-luminosity AGNs (LLAGNs) in the context of the advection-dominated accretion flow. The best investigated source, the supermassive black hole in our galactic center, Sgr A*, is emphasized since the physics of accretion should be the same for various LLAGNs except for their different accretion rates. The important role of jets is discussed, but this is less well established.
