Grammarly Inc. renames itself Superhuman Platform Inc., launches Superhuman Go

Grammarly Inc. renamed itself Superhuman Platform Inc. on October 29, 2025, three months after acquiring the AI email client Superhuman (July 1, 2025). The rename unified Grammarly’s writing assistant, Coda’s docs/workspaces, Superhuman Mail, and a new cross-app AI assistant called Superhuman Go into a single “Superhuman Suite.” TechCrunch’s story on the rebrand drew a 171-point, 130-comment Hacker News thread — well above this corpus’s 50-point trust-event threshold.

Grammarly’s own announcement (grammarly.com/blog/company/announcing-company-rebrand-to-superhuman) was explicit that the rename was not a pricing event: “For existing Grammarly, Coda, and Superhuman Mail customers, nothing changes about the products they rely on.” Superhuman Go itself was offered at no additional cost through February 1, 2026 as an introductory promotion.

This corpus’s own Wayback captures confirm the pricing claim: Grammarly’s Free ($0) and Pro ($12/member/mo annual) tiers on grammarly.com/pro did not move at the time of the rename, and stayed unchanged for many months afterward. The rebrand’s effect on Grammarly’s own pricing surfaces was delayed rather than immediate — see the separate 2026-06 change entry for when Grammarly’s Enterprise tier was actually re-platformed onto Superhuman Go.
