Our take— Notion AI wins
Based on our comparison of published pricing, features, and compliance data, Notion AI pulls ahead with SOC 2 certification and ISO 27001 certification. Windsurf stays close but doesn't lead on any single attribute here. Notion AI scores 8.0/10 to Windsurf's 7.6/10. If SOC 2 certification matters, go Notion AI; if it doesn't, Windsurf.
