The Grammarly add‑in for Microsoft Word on macOS has been discontinued. Grammarly has removed support for:
Word for Mac add‑ins (Office 365 / Microsoft 365)
Word 2019 / 2021 standalone on macOS
Word desktop integration via the old Grammarly Editor plugin
This is why:
The Insert → Add‑ins → Store search shows nothing
The Grammarly installer no longer offers Word integration
The DSA Grammarly EDU licences do not include Word‑for‑Mac support
The "sidebar" is no longer avail;able.
Grammarly’s official reasoning (summarised):
Microsoft changed the add‑in architecture for macOS, breaking legacy integrations.
Grammarly shifted to browser‑first and OS‑level writing assistance, not app‑specific plugins.
Maintaining Word‑for‑Mac compatibility required separate development pipelines that were no longer viable.
This applies to:
Grammarly EDU → English‑only
Grammarly Free → lower resource usage
Grammarly for Mac → system‑wide typing assistant, not app‑specific
Works across:
Word (via system‑wide typing suggestions, not embedded add‑in)
Pages
Notes
Safari/Chrome/Edge
Email clients
Full feature set, including:
Tone detection
Plagiarism checker (if licence includes it)
Rewrite suggestions
Citations
Chrome / Edge / Safari Supports:
Word Online
Outlook Web
Google Docs
VLEs / LMS platforms
No Word ribbon button
No side‑panel Grammarly editor inside Word
No inline Word‑specific grammar engine
No document‑sync Grammarly panel
Grammarly/Superhuman discontinued its native Editor apps for macOS and Windows. This is not the Word add‑in itself, but it marks the beginning of Grammarly’s retirement of legacy desktop integrations.
This is the first major retirement event in the chain.
The Grammarly Support page explicitly states:
“We have discontinued Grammarly for Microsoft Word on Mac.”
This page does not include a date, but we can anchor the change using external references:
Multiple Microsoft Q&A posts show users reporting that the Word‑for‑Mac Grammarly add‑in had already been retired:
Feb 28, 2026: “I was just informed that the Grammarly app has been retired.”
Mar 1, 2026: Moderator confirms: “Grammarly appears to have discontinued its Word-specific add-in on the Mac platform.”
Another user reports the plugin was retired, and the moderator links to the discontinuation page.
This confirms the retirement was already in effect.
Because:
The discontinuation page existed by Feb–Mar 2026,
Users were already unable to install the add‑in,
Grammarly had begun retiring legacy desktop integrations in 2024,
The Word‑for‑Mac add‑in was discontinued sometime between mid‑2024 and early‑2026, with the change becoming publicly visible and widely acknowledged by February 2026.
The Grammarly for Word add‑in on macOS was discontinued before February 2026, with public confirmation appearing between February 28 and March 1, 2026. The retirement likely occurred in late 2024 or 2025, but the earliest confirmed public evidence is Feb–Mar 2026.
