In this talk we show how different conditions that effective field theories consistent with quantum gravity must satisfy, known as Swampland Conjectures, can be used to make predictions in particle physics. We start with a discussion of the Weak Gravity Conjecture. Then we discuss how a sharpened version of it by Ooguri and Vafa allows us to obtain predictions about neutrino masses. We use toroidal compactifications of the Standard Model down to 2 and 3 dimensions. We also obtain results which can guide us finding the correct beyond Standard-Model physics. We proceed with scalar extensions of the Weak Gravity Conjecture. In particular, we explore different predictions that can be made with a Strong version of the Scalar Weak Gravity Conjecture. Among other results, essentially the same neutrino bounds are obtained. We discuss the several caveats and hypothesis used to make these predictions. Finally, we show how yet another Swampland criteria can be used to make contact with observations: the AdS Distance Conjecture. We show how it also implies essentially the same neutrino bounds.
