Our take— Grammarly wins
Based on our comparison of published pricing, features, and compliance data, Grammarly takes the overall edge, though Notion AI offers GDPR compliance and a no-training-on-your-data policy. Grammarly scores 8.1/10 to Notion AI's 8.0/10. Pick Notion AI if GDPR compliance matters — Grammarly takes it overall on our scoring, but the gap is narrow.
