Grammarly
AI writing assistant, now inside a broader productivity suite
- Overview
- Grammarly is an AI writing assistant that catches grammar, spelling, tone, and clarity issues in real time across browsers, desktop apps, and mobile — used by over 40 million people daily. Its Pro plan includes brand voice controls, style guides, and 2,000 AI prompts per month at $12/mo (annual). Note: Grammarly's parent company rebranded to 'Superhuman' in October 2025 after acquiring the Superhuman email client and Coda; the Grammarly writing product retains its name and continues to operate as before.
- Why it matters
- Grammarly is notable less for grammar-checking than for its distribution: it sits inside the browser and every major writing surface, making it the default AI writing layer for millions of knowledge workers without a deliberate procurement decision. The October 2025 parent rebrand to 'Superhuman' — after acquiring both the Superhuman email client and Coda — signals a push toward a bundled productivity suite, which introduces both upsell pressure and a new competitive dimension against Microsoft 365 Copilot. Teams evaluating Grammarly should track whether features migrate exclusively to higher bundle tiers and how the Authorship tracking capability evolves in regulated or education contexts.
- In practice
- RevOps and customer-success teams use Grammarly's Brand Voice feature to enforce messaging consistency in outbound emails, LinkedIn posts, and support tickets without a manual review step. Content teams integrate it into Google Docs and Notion for in-line editing, using AI prompts to rewrite for different audiences in the same draft. The main limitation is that the 2,000 monthly AI prompt cap on Pro depletes quickly for heavy generative use, and the Superhuman Business bundle at ~$33/mo may be hard to justify unless teams already want the Superhuman Mail client.
