Our take— Grammarly wins
Based on our comparison of published pricing, features, and compliance data, Grammarly scores 8.1/10 to Fathom's 7.5/10. Grammarly pulls ahead with SOC 2 certification and ISO 27001 certification. Fathom stays close but doesn't lead on any single attribute here. Grammarly is the call when SOC 2 certification matters — otherwise Fathom.
