Grammarly is a writing assistant that checks spelling, grammar, tone and clarity, and in recent years has added generative AI features such as rewriting and drafting. A lot has changed around it. On 29 October 2025 the company announced that it was renaming itself Superhuman, with Grammarly continuing as one product in a wider suite.
This review explains what Grammarly is today, what its plans and AI prompt limits look like on the official page, what the company says about privacy and AI training, and where it may not fit. We also flag a naming issue: when you read older articles about Grammarly, the company and some plan names may be different from what you see now.
How we researched this: we did not run hands-on tests for this article. It is based on the vendor’s own documentation and public sources, checked on 11 November 2026. Features and prices change, so confirm details on the vendor’s site before you buy.
Key takeaways
- The company behind Grammarly renamed itself Superhuman on 29 October 2025. Grammarly remains a product, alongside Coda, Superhuman Mail and a new assistant called Superhuman Go.
- The plans page lists Free at $0 with 100 AI prompts, Pro at $12 per member a month billed annually or $30 billed monthly with 2,000 AI prompts, and Enterprise through sales, as shown when we checked on 11 November 2026.
- Grammarly says users can opt out of having their content used to train models by turning off “Product Improvement and Training” in account settings.
- Grammarly Premium has been migrated to Pro for web subscribers, with billing amounts unchanged, according to its support page.
- Grammarly’s user numbers, customer names and testimonials are its own claims. We have not verified them.
What it is
Grammarly’s own AI page describes a set of writing tools and agents. These include a Proofreader that improves structure and phrasing as you write, a Paraphraser that rewrites text in a different tone while keeping the ideas, Reader Reactions that gives feedback based on a target reader, and a Humanizer that makes AI-assisted drafts sound more natural. The same page lists Citation Finder, AI Grader and Resume Builder, plus free tools such as a Grammar Checker, Plagiarism Checker, AI Detector and Translator. It also describes Docs, an AI document editor, and Go, an assistant that works across apps and tabs.
The Superhuman rename
Grammarly’s announcement, dated 29 October 2025 and updated 5 November 2025, says the company was renamed Superhuman and now unites Grammarly, Coda and Superhuman Mail under one brand, which it calls an AI-native productivity platform. A fourth product, Superhuman Go, was introduced as a proactive assistant that connects to more than 100 apps. The announcement says existing Grammarly, Coda and Mail customers see no change in the products they use, and that Go features were free until 1 February 2026. For a reader, the practical point is simple: the product is still called Grammarly, but the company name and some marketing now say Superhuman.
Who it is for
The plans page splits the audience into individuals (Free), individuals or teams (Pro, 1 to 149 seats) and larger organisations (Enterprise). Pro adds team features such as style guides, brand tones, knowledge share, snippets and usage analytics. The page says Pro is not available to Business or Education customers, or to Premium customers who subscribed through the App Store or Google Play, so check which route applies to you.
It suits people who write regularly in many places, such as email, documents and web forms, and want consistent corrections and tone suggestions. If you rarely write, or only need occasional proofreading, the Free plan may be enough to judge whether it is worth paying.

AI detection and authorship
The AI page describes an AI Detector that shows insights into how a text was created, and the announcement lists Grammarly Authorship among its feature names. Be careful with any tool that claims to detect AI-written text. We have not tested accuracy, and our guide on how to spot AI-generated text and images explains why such signals are uncertain.
Pricing model
Grammarly sells three tiers: a Free plan, a per-member Pro plan, and Enterprise through sales. The figures below come from the plans page as read on 11 November 2026. Prices change and may differ by region or billing route, so confirm them on the vendor page.
| Plan | Price shown | AI prompts | Notes |
|---|---|---|---|
| Free | $0 a month | 100 | Basic error checking, tone visibility |
| Pro | $12 per member a month billed annually, or $30 a month billed monthly | 2,000 | Full-sentence rewrites, tone adjustment, brand voice, team features; 1 to 149 seats |
| Enterprise | Contact sales | Unlimited | Confidential mode, roles and permissions, data loss prevention; offered through Superhuman Go |
What happened to Premium
A Grammarly support article says Grammarly Premium, sold through the App Store and Google Play, includes 1,000 generative AI prompts a month and is designed for individuals. Pro is sold through web purchase, includes 2,000 prompts and supports teams of up to 149 members. The article says Premium subscribers who bought directly from Grammarly’s website were being upgraded to Pro at no extra cost, that the migration began in March 2025 and rolled out gradually, and that there was no option to opt out. Prices were stated as not increasing. If you see older reviews that discuss Premium pricing, they may describe a plan that has since been replaced for web buyers.
Adding seats
The support article says adding seats to Pro incurs a prorated charge for each new member based on the time left until renewal. For team budgeting, multiply the per-member price by the number of seats and add the proration when people join mid-term. Our guide to reading an AI tool’s pricing page covers other per-seat details worth checking, such as minimum seats and billing routes.
Strengths
- A free tier to judge the basics. Free includes error checking, tone visibility and 100 AI prompts, so you can check the suggestions on your own writing before paying.
- Clear prompt allowances. The plans page and support article give explicit AI prompt numbers by plan.
- Team writing controls. Pro adds style guides, brand tones, snippets and analytics for consistency across a team.
- Documented privacy control. The trust page describes an account setting to opt out of content being used for model training.
- Broad tool set. From grammar to citations, the AI page lists many writing-related helpers under one brand.
Limits and cautions
- Naming changes. The company is now Superhuman, and plan names have shifted from Premium to Pro for web buyers. Older reviews can mislead.
- Billing route matters. Premium bought through app stores stays separate, and Pro is not available to those subscribers or to Business and Education customers, according to the plans page.
- AI prompt limits. Free has 100 prompts and Pro 2,000. Heavy AI users should check whether those limits fit.
- Vendor claims are unverified. The 40 million user count, 50,000 organisations and a 66% communication improvement testimonial on Grammarly’s pages are its own statements.
- Writing is still your responsibility. Suggestions and rewrites can change meaning, so review them. See how to check AI output for mistakes.
- A human service reads content. The trust page says writers in the expert writing service read submitted content to make edits.
Privacy and data
Because a writing assistant sees what you type, privacy is central. Grammarly’s trust page says it does not sell or monetise user content and earns revenue from paid subscriptions. It states that employee access to customer data is restricted to specific, audited permissions that require review and approval. The Superhuman announcement says third-party service providers are not allowed to train their models on user content and that users keep control of their data.
On training, the trust page says users can opt out by turning off “Product Improvement and Training” in account settings. It also says saved documents in the Grammarly Editor are stored until the user deletes them or the account, and that with tailored assistance on, Grammarly stores data linked to the account, which is deleted if you opt out of that feature. It states it collects personal information such as username, email address, contact details and language preferences, and that you can request a personal data report from your privacy settings.
| Topic | What Grammarly documents |
|---|---|
| Sale of content | Says it does not sell or monetise user content |
| Model training | Opt-out via “Product Improvement and Training” setting |
| Third-party providers | Not allowed to train models on user content, per the announcement |
| Certifications | Says it holds annual security certifications; details are on its Security and Compliance pages, which we did not read |
| Enterprise controls | Confidential mode and data loss prevention listed on the plans page |
Whether the opt-out applies by default on your plan, and exactly which products it covers, is worth confirming in writing. If you handle confidential material, read how to protect company data when using AI tools first, and consider whether a browser extension that reads every text box suits your policy.
Alternatives
We did not research other writing assistants for this article, so we do not compare named products. The sensible alternatives are other grammar and style checkers, the proofreading features built into the word processor or email client you already use, and general AI chat assistants that can edit text on request. When comparing, check prompt or usage limits, where your text goes, whether training can be disabled, and per-seat price. Our guide to how to compare AI tools side by side fairly offers a method.
| Option | What to compare |
|---|---|
| Other writing assistants | Limits, training controls, price per seat, browser permissions |
| Built-in editor features | What you already pay for, and whether it is enough |
| General AI chat tools | Control over tone prompts, data handling, extra review effort |
Who should and should not use it
Best for these people, if these conditions apply
- You write often across many apps and want inline suggestions without switching tools.
- You are happy with the Free tier’s limits, or you need Pro’s rewrites and team style rules.
- You have reviewed the training opt-out and are comfortable with how content is handled.
Look elsewhere, or test carefully, if these apply
- You handle highly confidential text and cannot get written confirmation of the training and retention terms.
- You buy through an app store and expect Pro features on that route.
- You want to rely on AI detection scores to judge other people’s work.
Questions to ask before buying
- Which plan do I need given the 100, 1,000 or 2,000 AI prompt limits?
- Where do I buy, and does that route make me eligible for Pro?
- Is the training opt-out on for my account, and does it cover every product I use?
- What are the retention terms for documents and tailored assistance data?
- How many seats do I need, and how will mid-term additions be charged?
- Does my organisation’s policy allow a writing assistant that reads text across apps?
A short trial on the Free plan with your normal writing is the cheapest check. How to test an AI tool before you pay for it lists what to record.
