The QSFit package allows to perform automatic analysis of optical/UV AGN spectra. The software is very easy to use (it just requires the input FITS file) and provides estimates of: emission line luminosities, widths and velocity offsets; host galaxy luminosities; iron lines luminosities at optical and UV wavelengths; Balmer continuum luminosities; continuum slopes and luminosities at several wavelengths; etc. I will present the analysis algorithm and the scientific exploitation of the first catalog of spectral properties, measured on a sample of ~80,000 SDSS spectra of type I AGN with z < 2 (Calderone et al. 2017, http://qsfit.inat.it). Also, I will show how to perform the analysis on new spectral data (regardless of the telescope/instrument used) and how to customize the procedure for specific needs. Finally, I will present the new capabilities of the upcoming version 2 of the software, namely: analysis of sources at z>2, fit of absorption lines, the Lorentzian profiles for absorption/emission lines, and the possibility to perform the analysis online using just a simple web browser.
