In the title compound, C15H12N4OS, the dihedral angle between the nine-membered indolin-2-one ring system and the phenyl ring is 2.72 (7)°. Intra­molecular cyclic N—H⋯O and C—H⋯S hydrogen-bonding inter­actions [graph set S(6)] are present, as are weak N—H⋯N inter­actions [graph set S(5)]. In the crystal, mol­ecules form centrosymmetric cyclic dimers through pairs of N—H⋯O hydrogen bonds [graph set R 2 2(8)] and these are extended by C—H⋯S inter­actions. The crystal structure also features weak C—H⋯π inter­actions
