The spectrum of single-trace local operators in N=4 Super Yang Mills, dual to Type IIB string theory on AdS5 x S5, in the planar limit can be encoded by a handful of Riemann-Hilbert relations for a set of so-called Q-functions. This integrability-based framework is known as Quantum Spectral Curve (QSC) and has allowed for extensive precision spectroscopy of N=4 SYM perturbatively, numerically at finite coupling and analytically in some regimes. 
QSC equations have recently been proposed for string theory on AdS3 x S3 x T4 with pure RR flux. In this talk I will review this construction and solve the resulting set of equations numerically at finite coupling and perturbatively at weak coupling. New tools are developed to deal with a salient feature of string theory on this background - massless modes. We obtain the first ever predictions for non-protected string excitations on this background and shed light on the mysterious CFT2 dual.
