Grammarly is working to reposition itself from a grammar-check utility into a broader agentic writing platform, adding a resume builder, a humanizer, and an authorship-transparency detector under the Superhuman umbrella since last year's acquisition. Conversation about it spans category leaderboards and growth-pattern case studies that cite it as a proof point, practitioner tips for using it to coach sales and executive writing, and a live debate over what a dedicated writing tool still adds once general chat models can also catch grammar and tone.

Business Profile
Grammarly has been building since 2009, growing into one of the largest AI writing products on the market with roughly 963 employees, $400M in funding raised, and revenue reported north of $700M and a $13B valuation as of mid-2025. In July 2025 Grammarly acquired Superhuman, the AI email client, and the following October the parent company took the Superhuman name for itself, an entity-level rebrand built to signal a wider agentic-productivity platform, while the Grammarly writing assistant continues to operate under its original, well-known brand alongside the newly acquired Coda suite.
Agent Readiness
Measures how easily your agents can build on it — API, MCP, CLI, SDK, docs depth. Methodology →
No public API, MCP, or SDK surface is on file for connecting outside agents to Grammarly's writing engine. The build-out so far is in-product — Grammarly brands several of its own features as agents (a humanizer, an AI detector, a resume builder, a reader-reactions tool), bundled into the same "agents built to amplify you" language now organizing the wider Superhuman platform since last year's acquisition.
