Nearby powerful AGN provide the best way to understand the growth of supermassive black holes and their effect on galaxies. The Swift-BAT 105-month survey comma with its all-sky coverage that is insensitive to obscuration up to Compton-thick levels comma provides the largest comma most complete sample of local (z<0.1) powerful AGN. These AGN have similar luminosities to the distant AGN typically found in deep comma pencil-beam Chandra surveys and are thus a critical nearby template for luminous high-redshift AGN. Despite containing the most luminous nearby AGN comma only five have have been imaged in the NUV. We propose a snapshot (SNAP) near UV survey (NUV comma <3000A) in the F225W filter of the 124 nearest and X-ray brightest AGN with black hole mass measurements from broad line Hbeta with existing V or I-band HST imaging. These sources only have NUV imaging with Swift-UVOT or XMM-Newton-OM where the spatial-resolution is 30x coarser and thus nuclear star formation and PSF emission are impossible to accurately separate. These virgul100 pc resolution observations will resolve the power output of local AGN and study the link of nuclear star formation with AGN activity.
