The unrivalled astrometric and photometric capabilities of the Gaia mission have given new impetus to the study of young stars: both from an environmental perspective, as members of comoving star-forming regions, and from an individual perspective, as targets amenable to planet-hunting direct-imaging observations. In view of the large availability of theoretical evolutionary models, both fields would benefit from a unified framework that allows a straightforward comparison of physical parameters obtained by different stellar and substellar models. Methods. To this aim, we developed MADYS, a flexible Python tool for age and mass determination of young stellar and substellar objects. In this first release, MADYS automatically retrieves and cross-matches photometry from several catalogs, estimates interstellar extinction, and derives age and mass estimates for individual objects through isochronal fitting. Harmonizing the heterogeneity of publicly-available isochrone grids, the tool allows to choose amongst 16 models, many of which with customizable astrophysical parameters, for a total of $\sim$ 110 isochrone grids. Several dedicated plotting function are provided to allow an intuitive visual perception of the numerical output. After extensive testing, we have made the tool publicly available (https://github.com/vsquicciarini/madys). We demonstrate here the capabilities of madys, summarising already published results as well providing several new examples.
