DreaMS Search

DreaMS Search is a free web application for deep-learning spectral search of tandem mass spectrometry (MS/MS) data. It finds structural analogues across 200M+ public spectra using the DreaMS model developed by Bushuiev et al. (Nature Biotechnology, 2025). Search a growing subset of the DreaMS Atlas and the annotated MassSpecGym reference library (GNPS, MoNA, and Pluskal lab data). Upload your own MS/MS spectra to find their analogues.
