We discuss the quantum correction to chaos in the Schwarzian theory. We carry out the semi-classical analysis of the Schwarzian theory to study Feynman diagrams of the Schwarzian soft mode. We evaluate the contribution of the soft mode to the out-of- time-order correlator up to order 𝒪 (g4). We show that the quantum correction of order 𝒪 (g4) by the soft mode decreases the maximum Lyapunov exponent \( \frac{2\pi }{\beta } \).
