Grammarly review (July 2026): what it does, what it costs, and who it is for

Grammarly is an AI writing assistant that runs where you already write, in browsers, on the desktop, in Google Docs and Microsoft Office, and on mobile keyboards. As of July 2026 it is developed by Superhuman Platform Inc. (formerly Grammarly Inc.), the same company that now owns Superhuman Mail, Coda, and Superhuman Go.

I have not run the product for this review. Everything below is sourced from Grammarly’s own pages, the Superhuman privacy policy, independent reporting, and security and vulnerability databases, so you can see exactly where each claim comes from.

What is Grammarly, in one paragraph

Grammarly is a subscription AI writing assistant: a browser extension, desktop app, mobile keyboard, and a long-form document surface called Docs that checks spelling, grammar, tone, and clarity and now also generates, rewrites, summarizes, and paraphrases text using large language models. The product is offered in three paid tiers (Plus/Pro, Business, Enterprise) plus a Free plan, and it plugs into more than 20 languages and what the company describes as over 1 million applications and websites through its extensions and SDKs.

How much does Grammarly cost in July 2026

Grammarly’s list pricing for the U.S. market in late July 2026 is $0 for Free, $12 per member per month for Pro when billed annually (about $30 monthly), and a custom quote for Enterprise. The company also markets a regional Plus plan in select countries (for example ₹392 INR per month, billed annually in India) with the same features as Pro but regional payment options.

Pricing disclaimer. Plans, prices, and regional availability change. The numbers above come from Grammarly’s Plans and Pro pages as of late July 2026 and may differ in your market or for renewals after introductory periods.

What features does Grammarly actually have

Grammarly’s product surface in July 2026 splits into four layers, and they are worth naming because “Grammarly” no longer means only the red squiggle.

1. Core editing. Spell, grammar, punctuation, clarity, and tone detection that run inline in the editor, browser extension, and mobile keyboard.
2. AI agents. Specialized assistants such as Proofreader, Paraphraser, Reader Reactions, and Humanizer that critique or rewrite what you have written, plus generative drafting on a blank page. The Pro plan ships 2,000 generative prompts per member per month; Enterprise is unlimited.
3. Team and brand controls. Style guides, brand tones, snippets (reusable reply blocks), and knowledge share that surfaces company acronyms, definitions, and documents inline as you type.
4. Agentic surfaces. Superhuman Go, an AI assistant that follows you across apps and tabs, and Docs, a long-form editor built for working with agents from first idea to final draft. Both are positioned by the company as a unified “AI superhighway” across more than 500,000 applications and websites.

The company also markets an AI Detector and Authorship report that try to estimate how much of a document is human-written versus AI-generated or copied, and a Plagiarism Checker that compares text against web and ProQuest sources. The Features and AI pages list the same agent set, which is the most reliable signal that they are stable across the product rather than experimental.

Privacy and security: what Grammarly says and what is documented

Privacy is where the most interesting 2026 story is, so I am pulling it apart carefully.

What Grammarly commits to in writing

• The Privacy Policy (effective July 6, 2026) is published by Superhuman Platform Inc. and explicitly covers Grammarly, Docs, Superhuman Go, and Superhuman Mail.
• Grammarly says it does not sell or monetize user content; revenue comes from paid subscriptions. The same language appears on the Trust Center, the Responsible AI page, and the Business page.
• The company states it does not allow its third-party AI service providers to train their models on Superhuman customer content. This is the same wording used on the Responsible AI page and the acquisition blog.
• Users can opt out of having their content used to train Grammarly’s own models through a Product Improvement and Training Control in account settings, and a Tailored Assistance toggle on the Feature Customization page.
• Enterprise admins can apply domain controls, application controls, and a Confidential mode; Enterprise also supports enterprise key management (BYOK), data loss prevention, and an Audit Logs API.

What is independently documented

• Infrastructure. Grammarly’s Security page says it hosts data in Amazon Web Services US East, encrypts data in transit with TLS 1.2, and encrypts data at rest with AES-256 through AWS KMS.
• Certifications. The Security page lists SOC 2 Type 2, SOC 3, ISO/IEC 27001:2022, ISO/IEC 27017:2015, ISO/IEC 27018:2019, ISO/IEC 27701:2019, ISO/IEC 42001:2023 (for responsible AI), PCI DSS, Cloud Security Alliance STAR, and alignment with NIST CSF, NIST Privacy Framework, and NIST AI RMF. The Trust Center and Security page agree on this list.
• Privacy frameworks. The Privacy Policy states that Superhuman Platform Inc. is certified under the EU-U.S. Data Privacy Framework, the UK Extension, and the Swiss-U.S. Data Privacy Framework.
• Bug bounty. A public HackerOne program is listed on both the Security page and the HackerOne directory, and the Security page references third-party network penetration testing.
• Past vulnerability. A 2018 flaw in the Grammarly browser extension (authenticated tokens exposed to all websites) was reported by Google’s Tavis Ormandy, hot-fixed within hours, and is recorded as CVE-2018-6654 in the MITRE CVE database. Grammarly publicly says it found no evidence of compromise, and the company launched its HackerOne bug bounty program later that year.
• March 2026 Expert Review controversy. Grammarly introduced an “Expert Review” feature in 2025 that simulated critiques from named authors such as Stephen King, Neil deGrasse Tyson, and bell hooks without their permission. Reporting by Wired, The Verge, TechCrunch, and the New York Times documented the backlash. On March 11, 2026, the same day journalist Julia Angwin filed a federal class-action lawsuit (Angwin v. Superhuman Platform Inc., 1:26-cv-02005), Superhuman announced it was discontinuing the feature.

What I would actually tell a buyer. The privacy and security program is among the most thoroughly documented I have seen for a writing assistant, but the March 2026 incident is a reminder that any AI feature that touches identity and likeness carries reputational and legal risk. If you handle regulated data, lean on the Enterprise admin controls rather than trusting defaults.

Company and product context: the Superhuman rebrand

In late 2025, Grammarly’s parent rebranded to Superhuman Platform Inc. to reflect the fact that the product had grown well past grammar checking. The acquisition history, as documented by Wikipedia citing TechCrunch, The Verge, Axios, and others, looks like this:

• December 2024: Grammarly acquires productivity tool Coda; Coda CEO Shishir Mehrotra becomes CEO of Grammarly.
• May 2025: Grammarly announces $1 billion in non-dilutive funding from General Catalyst.
• July 2025: Grammarly announces the acquisition of email client Superhuman.
• October 2025: The parent company rebrands as Superhuman and launches the new Superhuman Go AI assistant.
• February 2026: Superhuman acquires AI spreadsheet startup Rows to bolster Coda.
• March 2026: The Expert Review feature is launched, criticized, and withdrawn within weeks, and a class-action lawsuit is filed.

The rebrand is not just cosmetic. The Trust Center, Business page, and acquisition blog all describe the same “AI superhighway” that ties Grammarly’s writing layer to Superhuman Mail, Coda, and Go. If you are evaluating the product, you are really evaluating a small platform, not a single tool.

Grammarly pros and cons

What Grammarly is good at

• It is everywhere you already write. The official Features and Business pages list Gmail, Outlook, Google Docs, Microsoft Word, Slack, Teams, Notion, LinkedIn, Salesforce, Zendesk, Jira, and Figma, plus desktop apps for Windows, Mac, Linux, and mobile keyboards for iOS and Android.
• It is multilingual. Grammarly’s Features and Business pages both say the assistant supports more than 20 languages with inline translation and paragraph-level rewrites.
• The free tier is genuinely useful. Spelling, grammar, tone detection, and 100 generative AI prompts per month without paying anything, as listed on the Plans page.
• Strong security and privacy documentation. SOC 2 Type 2, ISO 27001/27701/42001, PCI DSS, EU-U.S. Data Privacy Framework, AES-256 at rest, TLS 1.2 in transit, and a public bug bounty program.
• Real admin controls for teams. SAML SSO, SCIM, BYOK, DLP, audit logs, confidential mode, custom roles, and a Feature Management Hub for Enterprise.

What Grammarly is less good at

• Heavy long-form drafting is not the focus. Superhuman Go and Docs cover it, but the core product is built around editing existing prose, not building a 5,000-word brief from scratch.
• Regional pricing is uneven. The same Pro plan can cost $12 USD in the US and roughly the local equivalent elsewhere, and some markets get a regional Plus plan with different payment options.
• The brand and product surface is sprawling. Grammarly, Superhuman Mail, Coda, Superhuman Go, Docs, and an Agent Store blur together, and not every feature is in every plan.
• AI detection is unreliable by design. Grammarly’s own marketing is careful here, and an AI Detector is best treated as one signal among many. Universities have documented cases where Grammarly-edited text was misflagged as AI-generated.
• There is a documented history of reputational risk around AI features. The Expert Review episode in March 2026 is the most visible example, and it shows that new AI surfaces can be pulled back quickly.

Who Grammarly is for, and who should skip it

Buy or standardize on Grammarly if you

• write a high volume of email, customer support replies, sales follow-ups, or internal docs and want a single ambient quality layer that runs in every app;
• need to enforce brand voice, terminology, or compliance language across a team of 10 or more and want admin controls to back it up;
• operate in a regulated industry and need certifications (SOC 2 Type 2, ISO 27001, ISO 27701, EU-U.S. DPF) and BYOK encryption that procurement will accept;
• already use or are evaluating the broader Superhuman platform (Mail, Go, Coda) and want writing quality tied to the same agents.

Skip it or pair it with something else if you

• need a long-form content marketing engine, brand voice generation, or multi-step campaign automation. Jasper, Copy.ai, or a custom workflow on top of a general LLM will serve you better.
• mainly need a research and citation assistant, where Perplexity or a retrieval tool is a better primary.
• want a single chat workspace for writing, coding, and analysis, where ChatGPT or Claude is a better all-in-one.
• are an individual who only needs occasional spell-check and does not want a subscription. Browser and operating system spell-checkers cover most of that need.

Grammarly vs the obvious alternatives

Tool	Best fit	How Grammarly compares
ChatGPT	General drafting, analysis, coding help	Grammarly wins on inline correction and ambient quality; ChatGPT wins on long-form generation and reasoning
Claude	Long-form writing, careful reasoning	Similar story to ChatGPT; choose Claude for deeper editing, Grammarly for always-on polish
Perplexity	Citation-first research	Different job; pair with Grammarly rather than replace
Jasper	Marketing content production systems	Jasper is a content ops platform; Grammarly is a quality layer that complements it
Microsoft Editor	Office-centric shops on a Microsoft budget	Cheaper and tightly integrated with Word; lighter on tone, brand, and team features
LanguageTool	Open-source and privacy-sensitive use cases	LanguageTool is cheaper and self-hostable; Grammarly is more polished and better supported in English

FAQ: the questions readers actually ask

Is Grammarly worth paying for in 2026?

It is worth paying for if you write professionally every day and want ambient correction and tone control across email, chat, and docs. If you only need occasional help, the Free plan is enough and the Pro upgrade is easy to skip.

How much does Grammarly Pro cost per month?

The list price on Grammarly’s Pro page is $12 per member per month when billed annually, or about $30 per month when billed monthly. Regional variants such as the India-only Plus plan are priced in local currency.

What is the difference between Grammarly Free and Pro?

Free gives you spelling, grammar, tone detection, and 100 generative AI prompts per month. Pro adds full-sentence rewrites, tone adjustment, plagiarism and AI detection, 2,000 generative prompts per month, and limited team features (style guide, brand tone, snippets, analytics) for up to 149 seats.

Is Grammarly safe for confidential work?

The Security page and Privacy Policy document AES-256 encryption at rest, TLS 1.2 in transit, AWS US East hosting, SOC 2 Type 2 and ISO 27001/27701/42001 certifications, and an EU-U.S. Data Privacy Framework certification. For regulated workloads, use the Enterprise plan’s BYOK, DLP, and Confidential mode, and confirm contract terms with your security team.

Can Grammarly see what I write?

The Trust Center and Privacy Policy say access is restricted to authorized personnel with audited permissions, and that only a small group may review your text when needed to fix an account problem or to deliver an expert writing service you have requested.

Does Grammarly sell your data?

Grammarly’s Privacy Policy, Trust Center, Responsible AI page, and Business page all state that the company does not sell or monetize user content and earns revenue from subscriptions. It also states that third-party AI providers are contractually restricted from training on Superhuman customer content.

What happened to Grammarly’s Expert Review feature?

Independent reporting by Wired, The Verge, TechCrunch, and the New York Times documented criticism of the “Expert Review” agent, which simulated advice from named living and deceased authors without their permission. Superhuman announced on March 11, 2026, the same day a federal class-action lawsuit was filed, that the feature was being discontinued.

Is Grammarly better than ChatGPT for writing?

For inline editing of things you are already writing, yes. For long-form drafting, ideation, and analysis, ChatGPT or Claude is a stronger choice. Many professionals use both.

What does Grammarly Enterprise include?

According to the Plans and Business pages, Enterprise includes everything in Pro, unlimited generative AI prompts, unlimited style guides and brand tones, SAML SSO, SCIM, BYOK encryption, data loss prevention, custom roles, audit logs, confidential mode, and dedicated support.

Is Grammarly now called Superhuman?

Grammarly is still the product name, but the parent company rebranded from Grammarly Inc. to Superhuman Platform Inc. in October 2025. You will see “© Superhuman Platform” on the Grammarly site’s footer and “Superhuman Platform Inc.” on the privacy policy.

Verdict: who should buy Grammarly in July 2026

Grammarly is the strongest ambient writing-quality layer on the market for people who write in many places every day. The 2025 to 2026 product changes, the Coda and Superhuman acquisitions, the Superhuman rebrand, and the agentic surfaces in Superhuman Go and Docs have turned a grammar checker into a small productivity platform. The free plan is genuinely useful, the Pro plan is fairly priced for daily writers, and the Enterprise plan has the certifications and admin controls that larger organizations need.

The honest caveats matter, though. Plan names and prices change region by region. The AI surface is sprawling, and not every new feature will age well; the Expert Review episode in March 2026 is the clearest example. And if your main job is long-form drafting, marketing content production, or citation-first research, Grammarly is the wrong primary tool, even if it is a great secondary one.

Bottom line. Standardize on Grammarly for ambient quality and brand consistency. Pair it with a general assistant like ChatGPT or Claude for heavy drafting and a specialist like Perplexity for research. Skip it as a campaign content engine.
