Torii tracks SaaS usage across enterprise customers worldwide. One trend has been hard to ignore: Grammarly’s footprint has grown roughly 3x in three years.
In January 2023, Grammarly appeared in just 17% of customer environments. By January 2026, it had jumped to 47%. The growth wasn’t steady — it came in three distinct waves, each driven by something specific Grammarly did.
Here’s what the data looks like, and what was happening at Grammarly each time the line jumped.
| Period | Adoption Index | Notable Change |
|---|---|---|
| Jan 2023 | 17% | Baseline |
| Feb–Mar 2024 | 22% → 31% | Spike 1: +6 points in one month |
| Dec 2024 → Jan 2025 | 30% → 38% | Spike 2: +7 points and never dropped back |
| Sep–Oct 2025 | 41% → 46% | Spike 3: +5 points as Grammarly became Superhuman |
| Jan 2026 | 47% | Peak to date |
Spike 1 (Feb–Mar 2024): Grammarly stopped being a spell-checker
On March 26, 2024, Grammarly launched Strategic Suggestions — AI-powered recommendations that went beyond fixing grammar to advising on audience, tone, and persuasion. The same week, it shipped App Actions, letting users trigger tasks in tools like Asana and Google Calendar from within Grammarly. For the first time, the product could make a real case to IT and procurement as a productivity platform, not a writing add-on.
Fast Company added fuel. Its 2024 Most Innovative Companies list (published March 19) named Grammarly in the AI category and cited some striking ROI numbers: one healthcare customer reported 28x ROI, and Grammarly claimed average savings of $5,000 per employee per year. That kind of coverage circulates in the procurement channels where enterprise software decisions get made.
Strategic Suggestions made Grammarly defensible as a productivity investment. Before this, it was mostly a tool employees added themselves. After it, IT had a product story to bring to leadership.
Spike 2 (Dec 2024–Jan 2025): A new CEO, a new company
On December 17, 2024, Grammarly announced it was acquiring Coda — a collaborative workspace product competing with Notion and Google Docs — and that Coda’s co-founder Shishir Mehrotra would become Grammarly’s new CEO. The message was explicit: Grammarly was no longer a writing tool; it was building an AI productivity suite for enterprise teams.
That announcement closed a pipeline that had been building since October. Two months earlier, Grammarly had landed on the AWS Marketplace, giving companies with existing AWS commitments a way to apply cloud credits toward Grammarly Business — a procurement shortcut that removes significant friction. In the same October window, Grammarly launched Billing Groups, ServiceNow integration, and group-level security controls: the exact features IT admins need before they can deploy something organization-wide.
The jump from 30% in December to 38% in January reflects deals that probably started in Q4, enabled by the AWS listing and admin tooling, then accelerated by the Coda news.
Spike 3 (Sep–Oct 2025): The Superhuman rebrand
On July 1, 2025, Grammarly acquired Superhuman — the AI email client valued at roughly $825 million. Three months later, on October 29, Grammarly rebranded the entire company as “Superhuman” and launched the Superhuman Suite: four unified products (Grammarly writing, Coda workspace, Superhuman email, and a new AI agent platform called Superhuman Go). The rebrand landed across TechCrunch, Fast Company, Built In, and others simultaneously.
Usage in our dataset went from 35% in August to 41% in September and 46% in October. September also brought a Forbes Cloud 100 placement at #11 — the kind of analyst recognition that validates a platform to IT procurement teams evaluating AI investments. A $1 billion non-dilutive funding round announced in May, earmarked for sales and marketing scale, almost certainly put more reps in front of enterprise buyers during this window.
When Grammarly became Superhuman, it stopped competing with Grammarly Premium and started competing with Microsoft 365 and Google Workspace. Enterprise IT teams evaluating the new suite were making a different kind of decision than they were in 2023.
What this means for IT teams managing SaaS
Each of these spikes followed the same pattern: Grammarly expanded what the product does, and enterprise adoption followed. That creates a specific challenge for IT.
In 2023, most companies probably had Grammarly as an employee-purchased tool — a $12/month browser extension people expensed without telling IT. By 2026, the product has become a full AI productivity suite with admin controls, data governance features, and enterprise licensing that IT should be part of evaluating and managing.
If you’re not tracking which tools are gaining momentum in your organization, you’ll find out about the enterprise version of Grammarly (or Superhuman, now) after someone in marketing has already signed a contract. The best position is to see the adoption curve before the renewal conversation happens.

FAQ
Based on Torii usage data, Grammarly’s presence across customer environments grew roughly 3x between January 2023 and January 2026. The growth came in three distinct spikes tied to specific product launches and acquisitions.
Grammarly launched Strategic Suggestions in March 2024, which expanded the product from grammar correction to AI-powered communication coaching. The same month, Fast Company named Grammarly one of its Most Innovative Companies in the AI category. Both events drove enterprise interest that showed up as increased adoption.
In October 2024, Grammarly launched on the AWS Marketplace and released enterprise admin features including ServiceNow integration and Billing Groups. In December 2024, Grammarly announced the acquisition of Coda and a new CEO, signaling a shift from a writing tool to a full AI productivity platform. These events collectively drove adoption from 30% of Torii customers in December to 38% in January 2025.
In October 2025, Grammarly rebranded the entire company as Superhuman and launched the Superhuman Suite — a unified platform combining Grammarly writing, Coda workspace, Superhuman email, and a new AI agent product called Superhuman Go. The rebrand followed Grammarly’s acquisition of the AI email client Superhuman in July 2025.
SaaS management platforms like Torii automatically discover and track which tools employees are using across the organization, even before IT officially sanctions them. This gives IT visibility into emerging tools and usage trends — so they can evaluate, govern, or negotiate licenses before users or departments make enterprise commitments independently.
