Our take— Replit wins
Based on our comparison of published pricing, features, and compliance data, Replit scores 7.8/10 to QuillBot's 7.3/10. Replit pulls ahead with GDPR compliance and multi-factor authentication. QuillBot stays close but doesn't lead on any single attribute here. Replit is the call when GDPR compliance matters — otherwise QuillBot.
