After a brief review of the machinery of stochastic inflation, I introduce a model with a sharp transition in the potential and derive the statistics of the stochastic noise. Then I show how to calculate the probability distribution of curvature perturbations from the corresponding adjoint Fokker-Plack equation. Finally, I make some comments on the tail of the distribution and the relation with primordial black holes.
