Grammarly
AI writing assistant, now rebranding as Superhuman Platform for broader work tools.
Grammarly's grammar checking core is being commoditized by free AI features baked into Word, Docs, and Gmail, and its pivot to a work platform via Coda and Superhuman is still unproven.
Grammarly checks grammar and fixes writing in documents and emails for millions of people. The problem: ChatGPT, Claude, and free tools built into Microsoft Word, Google Docs, and Apple devices do the same thing for free or as part of packages people already buy. Grammarly's growth has slowed sharply (from 43% to 12% per year), so the company is trying to become a bigger workplace platform with email, scheduling, and AI agents instead of just a grammar checker, but this new direction is unproven and risky. The next year will decide everything: if the new platform strategy builds real customer lock-in and keeps enterprise clients paying, Grammarly survives and could grow; if not, the core grammar business keeps shrinking as free alternatives get better.

Outcome of Julia Angwin v. Superhuman Platform class-action (S.D.N.Y., filed March 2026). Shows brand and legal risk from the Superhuman rebrand and Expert Review feature.
- ARR claimed over $700M
- 40M+ daily active users claimed
- Revenue growth fell from 43% to 12% YoY
- Active class action lawsuit (Angwin v. Superhuman Platform) over Expert Review feature, filed March 11, 2026.
- Core grammar checking function commoditized by free native AI tools from Microsoft, Google, Apple.
- Unproven brand and platform pivot to Superhuman suite risks alienating existing Grammarly users.
- Revenue linked non dilutive debt facility ($1B, May 2025) could face worse terms if growth stays decelerated.
- Conflicting revenue figures between company claimed $700M ARR and third party GAAP estimates near $250M to $380M raise reporting transparency concerns.

- Is Grammarly profitable in 2026?
- Grammarly has not disclosed profitability. It claims annual revenue over $700 million and 40 million daily active users as of May 29, 2025, funded partly through $1 billion in non dilutive financing rather than equity, suggesting cash flow is still a work in progress rather than confirmed profit.
- Could AI replace Grammarly?
- Grammarly's core grammar checking function is increasingly commoditized by ChatGPT, Claude, and native tools like Microsoft Copilot and Apple Writing Tools. Analysts at Sacra note growth decelerated from about 43% YoY in 2021 to 2022 down to about 12% YoY in 2023 to 2024, tied to this competition, as of June 11, 2025.
- Is Grammarly laying off employees in 2026?
- Grammarly cut 230 employees, about 23% of headcount, on February 7, 2024, in what it called an AI focused restructuring. Headcount rebounded to about 1,700 by October 2024, then fell again to roughly 1,000 by April 2026, according to Latka data from July 2, 2026.
- Who owns Grammarly now?
- Grammarly remains privately held. Its parent corporate entity renamed itself from Grammarly Inc. to Superhuman Platform Inc. on October 29, 2025. It last priced equity at a $13 billion valuation in November 2021, with investors including Baillie Gifford and BlackRock.
- What is Grammarly's biggest competitor?
- Grammarly faces pressure from general purpose AI chatbots ChatGPT, Claude, and Gemini, plus native writing tools bundled by Microsoft (Copilot in Word and Outlook), Google (Gemini in Docs), and Apple (Writing Tools), all offering free proofreading that erodes Grammarly's original niche, per Sacra, June 11, 2025.
- Why did Grammarly rebrand to Superhuman?
- On October 29, 2025, Grammarly's parent renamed itself Superhuman Platform Inc., launching a suite combining Grammarly writing tools, the Coda workspace (acquired December 2024), Superhuman Mail (acquired July 2025), and a new AI agent layer called Superhuman Go, aiming for workflow lock in beyond grammar checking.
