Grammarly

Grammarly is an AI writing assistant used by 40 million people and 50,000 organizations. In 2025 its parent company acquired Coda and Superhuman Mail and rebranded to Superhuman, launching a proactive AI assistant called Superhuman Go. The writing product still ships under the Grammarly name across browsers, desktop, and mobile.

What sets it apartUbiquitous writing quality and tone assistance across everyday apps, rather than a single-purpose content marketing suite.

Quick Verdict

Grammarly is still the easiest writing upgrade most people can make. It runs quietly in your browser and catches the embarrassing stuff—typos, awkward tone, missing commas—before anyone else sees it. In 2026 it also comes with a serious AI productivity layer called Superhuman Go.

I keep recommending it to anyone who writes more than a paragraph a day. It saves me roughly 15 minutes every workday. The free plan is genuinely useful. Pro is worth the price if you live in email or write in a second language.

Skip it if you only need long-form AI drafting (use ChatGPT or Claude) or if you want a deep marketing campaign tool (use Jasper). For everyday writing quality and tone consistency across a team, nothing else has the same reach.

TL;DR: Grammarly in 2026 is a 40-million-user AI writing assistant built into your browser, desktop, and apps. The free plan covers grammar and tone. Pro at $12/month adds full rewrites, plagiarism checks, and AI agents. Enterprise adds SAML, SCIM, BYOK, and Superhuman Go’s proactive AI. Owned by Superhuman Platform Inc. after the 2025 rebrand.

What Grammarly Is (and Isn’t) in 2026

Grammarly is an AI writing assistant. It checks grammar, spelling, clarity, and tone while you type, then offers one-click rewrites when something sounds off. It runs as a browser extension, a desktop app, an iOS/Android keyboard, and inside Microsoft Word, Google Docs, Outlook, Slack, Notion, LinkedIn, Salesforce, and roughly a million other web surfaces.

In 2026, the company that builds Grammarly is no longer called “Grammarly Inc.” It’s Superhuman Platform Inc., after a rebrand that followed the acquisitions of Coda (December 2024) and Superhuman Mail (July 2025). The Grammarly product name, though, stayed the same. Shishir Mehrotra, formerly Coda’s CEO, runs the whole Superhuman Platform.

The rebranding matters because of what it implies. Grammarly is no longer positioning itself as a grammar checker with bells on. It’s positioning itself as the writing surface for a broader AI productivity suite: Grammarly for editing, Superhuman Mail for inbox, Superhuman Docs for team docs, and Superhuman Go as a proactive assistant that runs across all of them.

What Grammarly is not: it’s not a full marketing content platform like Jasper. It’s not an open-ended AI chat tool like ChatGPT. It’s not a code IDE plugin like Cursor. And it’s not a stand-alone research or long-form writing tool. Its job is to make the text you already have to write sound sharper, clearer, and more on-brand.

Who Should Use Grammarly in 2026

Grammarly fits a pretty wide audience. Here’s where it pulls the most weight:

• Customer support and success teams who answer dozens of messages a day. Tone suggestions save them from sounding curt or sloppy when they’re tired.
• Non-native English writers who need real-time grammar and fluency help. Grammarly supports 20+ languages, including paragraph-level rewrites in Spanish, French, German, Portuguese, and Italian.
• Sales reps drafting follow-ups and outreach at speed. The “Adjust tone” feature alone pays for the subscription.
• Marketing teams that need consistent voice across copy, emails, social, and landing pages. The Business plan includes style guides and brand tones.
• Students and academics who want proofreading and citation help. Grammarly for Education offers institutional controls.
• Enterprise IT and security that need SAML SSO, SCIM provisioning, BYOK encryption, audit logs, and DLP. Grammarly holds SOC 2 Type 2, ISO 27001:2022, ISO 27701, ISO 27017, ISO 27018, and ISO 42001.

If your main job is long-form ideation, deep research, or campaign-level marketing automation, pair Grammarly with a different tool. It’s a co-pilot, not an autopilot.

Latest Features & 2026 Updates

Grammarly shipped a lot in the past 12 months. Here are the highlights I think matter most in July 2026:

1. Superhuman Go (October 2025). A proactive AI assistant that lives in the Grammarly sidebar and works in any tab. Go can draft an email reply, summarize a Slack thread, schedule a meeting, or pull context from Gmail, Google Drive, Jira, and Salesforce. It’s bundled with paid Grammarly plans through at least February 2026 at no extra cost.
2. Multilingual expansion (May 2025). Grammarly now supports 20+ languages, including Spanish, French, German, Portuguese, Italian, Polish, Dutch, Korean, Ukrainian, and Hindi. Real-time spelling and grammar are free; advanced clarity and tone suggestions are paid.
3. Specialized AI agents (August 2025). Four purpose-built agents ship with paid plans: Proofreader for stronger structure, Paraphraser for tone variants, Reader Reactions for “how will this land?” feedback, and Humanizer for softening AI-flavored text.
4. Grammarly Docs AI editor. An AI-native long-form writing surface inside the Grammarly app. The companion web editor handles brainstorming, drafting, and citation work in one place.
5. Authorship and AI detection. Grammarly’s AI detector ranks among the top performers on the RAID benchmark. Authorship tracks whether a passage was typed, pasted, or generated.
6. GPTZero acquisition (June 2026). Superhuman agreed to buy GPTZero, the AI content detection platform built by Edward Tian. Expect tighter AI authenticity detection inside Superhuman Go once integration ships.
7. Superhuman Docs launch (July 2026). Coda has been rebranded as Superhuman Docs, with rebuilt AI assistant capabilities and a new Superhuman Databases beta for enterprise-scale data management.
8. Knowledge Share and Style Guides. On Business and Enterprise, teams can upload their own style guide and brand voice. Knowledge Share surfaces company context inside any writing surface where Grammarly runs.
9. Plagiarism detection and citation help. Still part of Pro, still linked to a large web corpus.
10. Mobile keyboards. Grammarly Keyboard ships for iOS and Android, with multilingual spelling and grammar in up to 24 languages on Android.

A note about one feature that did not survive the year: Expert Review, a feature that simulated living and deceased authors like Stephen King, Carl Sagan, and bell hooks, was discontinued on March 11, 2026. It was the same day journalist Julia Angwin filed a federal class-action lawsuit. The Verge and Wired covered the backlash in detail.

Grammarly vs Alternatives (Comparison Table)

Here’s how Grammarly stacks up against the most common alternatives in 2026. Pricing and feature checks were done in July 2026.

Tool	Best for	Free tier	Paid price (US)	Generative AI	Inline everywhere	Enterprise SSO/SCIM	Brand voice
Grammarly	Everyday writing quality + tone across all apps	Yes (100 prompts)	$12/mo Pro, $33/mo Business	Yes (2,000+ prompts)	Yes (browser, desktop, mobile)	Yes	Yes (Business+)
ChatGPT	Open-ended ideation, long-form drafting	Yes	$20+/mo Plus	Yes (unlimited)	Limited (extension only)	Yes (Team/Enterprise)	Custom GPTs
Claude	Long-form reasoning, code, documents	Yes	$20+/mo Pro	Yes	Limited (extension)	Yes	No
ProWritingAid	Fiction/long-form editing	Limited	~$30/mo Premium	Light	Limited	No	Limited
LanguageTool	Multilingual + privacy-focused	Yes	~$5–15/mo Premium	Basic	Yes (browser)	Limited	No
Hemingway Editor	Readability scoring, simple prose fixes	Yes (web)	~$20/mo Plus	No	No	No	No
QuillBot	Paraphrasing, summarizing, citation help	Yes	~$10/mo Premium	Yes	Yes (extension)	Limited	No
Jasper	Marketing campaign production	No	~$49/mo Pro	Yes (campaigns)	Limited	Yes	Yes (brand voice)

Quick takeaways:

• Grammarly wins on cross-app coverage and tone consistency for individuals and teams.
• ChatGPT/Claude beat Grammarly for open-ended drafting, reasoning, and original content creation.
• ProWritingAid is the strongest competitor for book-length fiction and academic editing, but it lives mostly inside its own editor.
• LanguageTool is the privacy-first, open-source-leaning alternative with broader language support (30+).
• Hemingway is great for readability scoring if you want ruthless simplicity, but it won’t fix grammar or generate text.
• QuillBot is cheaper and better at paraphrasing, but lighter on inline grammar and team features.
• Jasper is for marketing teams that need campaigns and brand voice, not everyday grammar help.

Real-World Use Cases

Three concrete ways people actually use Grammarly in 2026:

1. Support and customer success. A support rep is answering the same kind of question for the fifteenth time. Grammarly drafts the reply in their voice, suggests a friendlier tone, and checks that the company name is spelled correctly. The rep edits instead of writing from scratch. Zoho-owned companies and Salesforce users often run Grammarly directly inside the support tab.

2. Marketing copy review. A content team gets a draft from a freelance writer. Grammarly’s style guide flags any wrong product name, off-brand phrases, or banned jargon. The editor doesn’t have to read word-for-word; Grammarly does the line edit. A Databricks case study published by Grammarly says the company saves roughly $1.4 million a year and gets 50% fewer editing hours back. That number is vendor-reported and not independently audited, but it’s consistent with multiple team testimonials.

3. Non-native English writing. A team member in Berlin or Bangalore writes an email in English. Grammarly catches dropped articles, awkward phrasing, and tone that comes across too blunt. They fix the red and blue underlines and send. The recipient can’t tell it wasn’t a native writer’s email. This is where the multilingual expansion matters most.

Other solid use cases: cover letters and resumes (Resume Builder and AI Grader agents), academic writing (Citation Finder and AI Grader), social media posting (LinkedIn integration), and meeting follow-ups (Superhuman Go pulls notes from Calendar).

Limitations & Gotchas

Let me be honest about where Grammarly falls short in 2026:

• Generative output still needs human review. Like all LLM-based tools, it can invent facts, hallucinate citations, and over-smooth distinct voices into bland corporate-speak. Don’t ship AI-generated copy without reading it.
• Pricing varies wildly by region. If you’re buying for a team in India or the EU, verify the local plan names. The US “Pro” is roughly $12/month; the India “Plus” is ₹392/month and is not identical in feature mix.
• It can’t replace a CMS or campaign workflow. If you need end-to-end marketing operations—brief, draft, review, publish, analyze—you still need a tool like Jasper, Writer, or a CMS. Grammarly edits in place.
• Over-acceptance flattens voice. Teams that auto-accept every suggestion end up sounding like everyone else. Use tone suggestions as a sanity check, not a rule.
• The Expert Review incident hurt trust. In March 2026, Superhuman pulled the feature after backlash and a class-action lawsuit over simulating real authors without permission. The company says it does not allow third-party AI providers to train on user content, and its responsible AI white paper lays out a risk-assessment process. Still, the episode is a reminder that AI assistants can overreach.
• Mobile keyboards are decent but not best-in-class. Apple’s built-in keyboard and Gboard are faster and more reliable. Grammarly Keyboard is most useful when you actually want rewrites on the go.
• No reliable offline mode. If you write on planes or in secure environments without internet, you’ll miss the cloud-based suggestions.

Privacy, Security & Compliance

This is where Grammarly tends to win enterprise deals. As of July 2026 the product carries:

• SOC 2 Type 2 — annual audit covering security, privacy, availability, and confidentiality.
• ISO/IEC 27001:2022 — information security management.
• ISO/IEC 27701:2019 — privacy information management.
• ISO/IEC 27017:2015 — cloud services security.
• ISO/IEC 27018:2019 — protection of personally identifiable information in the cloud.
• ISO/IEC 42001:2023 — responsible AI management system.
• PCI DSS — for payment data.
• NIST CSF, NIST Privacy Framework, and NIST AI RMF alignment.

Data is hosted on AWS US East, encrypted with AES-256 at rest and TLS 1.2 in transit. Enterprise customers can use their own keys (BYOK) and turn off model training on their content. SAML SSO, SCIM provisioning, custom roles, audit log API, data loss prevention, and session timeout controls are all Enterprise-tier features.

Grammarly’s public position: the company does not sell or monetize user content, and it does not allow its third-party AI service providers to train their models on user content. Users can opt out of product-improvement training in their settings.

One historical note worth flagging: in February 2018, security researcher Tavis Ormandy disclosed a vulnerability (CVE-2018-6654) in the Grammarly browser extension that exposed authentication tokens to websites. Grammarly patched it within hours and found no evidence of compromise. The company has run a HackerOne bug bounty program since December 2018.

Is Grammarly worth paying for in 2026?

Yes, if you send a lot of email, write for work in a second language, or manage brand voice across a team. Pro at $12/month pays for itself if it saves you even 20 minutes a week. If you only need a basic spell-check, the free plan is fine and you’re paying nothing.

Grammarly Free is $0. Pro is $12/member/month billed annually or $30 monthly. Business is $33/member/month annually or $60 monthly. Enterprise is custom. India pricing is different: Plus is ₹392/month annual. Always check grammarly.com/plans before buying.

Yes, for most enterprises. Grammarly is SOC 2 Type 2 audited, ISO 27001:2022 certified, and compliant with GDPR, CCPA, and HIPAA-ready controls for Business and Enterprise. It does not sell user content. You can opt out of model training and use your own encryption keys on Enterprise.

Superhuman Go is a proactive AI assistant that works in any app where Grammarly runs. It can draft emails, summarize threads, log tickets, and schedule meetings using context from Gmail, Calendar, Jira, and Salesforce. It ships to paid Grammarly subscribers at no extra cost through February 2026; after that, bundle pricing applies.

Yes. The Free plan includes 100 AI prompts a month, plus spelling, grammar, tone detection, and a basic AI detector. Pro unlocks 2,000 monthly prompts, full-sentence and paragraph rewrites, plagiarism detection, and the four specialized AI agents (Proofreader, Paraphraser, Reader Reactions, Humanizer).

Does Grammarly work in Google Docs, Gmail, and Microsoft Word?

Yes. The browser extension adds suggestions inside Google Docs, Gmail, Outlook web, Slack, Notion, LinkedIn, and most other web apps. Microsoft Word users get a dedicated add-in. Mobile keyboards are available for iOS and Android.

How does Grammarly compare to ChatGPT, QuillBot, or LanguageTool?

Grammarly is best for inline grammar and tone across every app. ChatGPT and Claude are best for open-ended ideation and long-form drafting. QuillBot is cheaper for paraphrasing. LanguageTool is open-source-leaning and supports more languages. The comparison table above gives the full breakdown.

Can schools and students use Grammarly for free?

Yes. Students get a free basic Grammarly account with grammar and tone help. Grammarly for Education adds institutional licensing, admin controls, and student discounts. Free multilingual support covers spelling and grammar in 17–24 languages depending on platform.

Why did Grammarly change its company name to Superhuman?

In October 2025, the parent company rebranded to Superhuman after acquiring Coda (December 2024) and Superhuman Mail (July 2025). The rebrand reflects a shift from “writing assistant” to “AI productivity platform.” The Grammarly product name stayed the same.

Final Verdict

Grammarly in 2026 is the most complete “everyday writing quality” tool you can buy. The free plan is actually useful, which is rare. Pro at $12/month is a no-brainer if you write for a living. Business at $33/month is the cheapest way I’ve seen to enforce brand voice across a team. Enterprise is for organizations that need real security controls.

What changed in the past year is the platform story. Superhuman Go, the Superhuman Mail bundle, the GPTZero acquisition, and the rebrand to Superhuman all signal that Grammarly is now the front door to a broader AI productivity suite. That has trade-offs—some users just want the grammar checker and don’t need an inbox tool—but it also means Grammarly is investing aggressively in the future instead of resting on its installed base.

If you’re choosing today: start free, upgrade to Pro the day you spend more than 30 minutes a day writing, and look at Business the moment you have three or more teammates who send customer-facing copy.

“It’s not what it does for me, it’s how it does it. It is integral in the way that we operate now. In a year it is part of our corporate DNA.” — Jimmy Snyder, Associate Director of Platform Support, on Grammarly’s business customer page
