The Opacity Wizard performs easy and fast visualizations of opacity and abundance data for exoplanet and brown dwarf atmospheres. It was designed to be used by observers studying these substellar objects as a way to explore which molecules are most important for a given planet and predict where the absorption features of those molecules will be. Opacity Wizard provides an iPython notebook with widgets for choosing a pressure, temperature, metallicity, and molecule list, and then create plots of the mixing ratios and opacities.
