The title compound, C15H12N2OS, adopts a twisted V-shape, with the S atom as the pivot. The benzimidazole ring system [maximum deviation = 0.015 (1) Å] makes a dihedral angle of 78.56 (7)° with the phenyl ring. The O atom of the ketone group is close to coplanar with its adjacent ring [O—C—C—C torsion angle = 11.0 (2)°]. In the crystal, mol­ecules are linked by N—H⋯N hydrogen bonds into an infinite chain along [001]. The crystal packing also features a C—H⋯π inter­action.
