Grammarly
The grammar checker itself hasn't changed much — the company behind it renamed itself Superhuman Platform Inc. after two acquisitions in twelve months, and that's reshaped what you actually pay for.
What is Grammarly?
Grammarly is still the grammar and writing assistant more than 30 million people use daily — catching spelling and punctuation errors, adjusting tone, rewriting full sentences, and flagging plagiarism or AI-generated text, across the browser, desktop, mobile, Microsoft Office, and Google Docs. What's genuinely changed is everything around it. In the space of twelve months, Grammarly's parent company acquired Coda (a documents and collaboration platform) in December 2024, took a large nondilutive raise from General Catalyst in May 2025, acquired the AI-native email client Superhuman that July, and then, on October 29, 2025, renamed the entire parent corporation to Superhuman Platform Inc. — with the Grammarly product itself continuing under its familiar name at the consumer level. A Rows acquisition (AI-powered spreadsheet and data tools, estimated at $50-70 million) followed in February 2026, further building out the Coda side of the business.
The unified suite that resulted bundles four things: Grammarly's writing assistance, Coda's collaborative documents, Superhuman Mail, and Superhuman Go — a new proactive AI agent the company says works "in all the apps you already use" and can help "without you needing to ask," handling tasks like drafting messages, scheduling meetings, and fetching data across connected apps like Gmail, Jira, and Google Calendar. The honest thing worth knowing before you pick a plan: getting access to Superhuman Mail specifically now requires the Business tier — there's no cheaper standalone way in for new users, and that tier bundles Grammarly Pro and Coda whether or not you actually want either of them. If all you need is the grammar checker, the free and Pro tiers still function on their own, and by August 2026 the writing side had expanded into 8 specialized AI agents — Reader Reactions, Grader, Citation Finder, Paraphraser, and others — giving genuinely more targeted feedback than a single generic AI suggestion.
Acquisition timeline and rebrand details are drawn from Grammarly's own October 29, 2025 announcement, TechCrunch reporting, and multiple independent 2026 analyses (sqmagazine.co.uk, Business Standard, Scroll.media, Agentys, AI:Productivity).

Our verdict
The actual writing product hasn't lost a step — Grammarly's grammar checking, tone adjustment, and new specialized AI agents remain genuinely strong, and the free and Pro tiers work perfectly well on their own if all you want is a grammar checker. What's genuinely changed is the company around it: a rename to Superhuman Platform Inc., two major acquisitions in a year, and a bundling structure where getting Superhuman Mail specifically means paying for Grammarly Pro and Coda too, whether you use them or not. That's a reasonable business strategy for a company betting on an integrated productivity suite, but it's worth going in with clear eyes about what you're actually paying for at each tier — the grammar checker you know is still there, just now sitting inside something considerably bigger.

Do I need to buy the whole suite just to use Grammarly's grammar checker?
