Our take— ChatGPT wins
Based on our comparison of published pricing, features, and compliance data, ChatGPT scores 8.7/10 to Devin's 7.8/10. ChatGPT pulls ahead with SOC 2 certification and multi-factor authentication. Devin stays close but doesn't lead on any single attribute here. Pick ChatGPT if SOC 2 certification matters; Devin is the pick if it doesn't.
