The study of azimuthal correlations of heavy-flavour hadrons with charged particles is an important tool to characterize charm fragmentation processes. It gives insight into the modi- fication of charm-jet properties in nucleus-nucleus collisions and the mechanisms through which heavy quarks in-medium energy-loss takes place. Studies in pp collisions, besides constituting the necessary baseline for nucleus-nucleus measurements, are important for testing pQCD-inspired Monte Carlo generators. In this proceeding, the latest heavy-flavour correlation results at mid- rapidity with the ALICE detector in pp collisions at 13 TeV are reported. The results are compared with pp ps 7 TeV and p-Pb at 5.02 TeV data. The yield of charged particles in the near-side correlation peak and the peak width measured in different systems are compatible, within the uncertainties, and described by Monte Carlo simulations.
