Grammarly Review 2026: Is It Still the Best AI Writing Tool for SMEs?
Grammarly is an AI writing tool that checks spelling, grammar, clarity, fluency, and tone in real time, and that also generates text, paraphrases, translates, and detects plagiarism. It belongs to the AI-Assisted Writing and Productivity category, although its scope has broadened in recent years toward specialized agents and, more recently, toward a larger ecosystem: Grammarly has been integrated with Superhuman, a suite that also includes Superhuman Mail, Coda, and Go, the proactive AI assistant that works across any browser-based app.
For an SME, a tool like Grammarly can make the difference between an email that closes a deal and one that falls through because of a tone slip or a confusing sentence. In small teams, where every person writes emails, proposals, social posts, and internal documentation, having a tool that automatically reviews text and offers context-aware suggestions makes the work easier and frees up time for higher-value tasks. It is one of the most complete options within the best AI writing tool category, especially for those who work in English or combine several languages.
AgentAya Verdict
Grammarly remains, in our view, the benchmark for AI-assisted writing correction when the primary language is English. Its review engine is advanced, offers well-explained suggestions, and works on practically every surface where people write, from the browser and desktop applications to mobile keyboards. The addition of AI agents such as Reader Reactions, Proofreader, Paraphraser, AI Grader, and Citation Finder makes it a tool that supports the user throughout the entire writing process, not just during final proofreading.
The bottom line: for SMEs that write heavily in English or need to polish content across multiple languages, Grammarly is well worth it.

AgentAya Overall Score: 4.4/5 ⭐⭐⭐⭐
Grammarly is hard to beat for SMEs that write a lot in English. An excellent starting point for multilingual teams.
Ideal for
- Small sales, marketing, or customer support teams that send emails every day.
- Freelancers and students who need to review long texts with rigor.
- Bilingual teams that switch between Spanish and English in emails, proposals, and documentation.
- Organizations that want to unify a brand tone through a shared editor across the entire workforce.
Not ideal for
- Companies whose content lives almost exclusively in Spanish and need to differentiate regional variants.
- SMEs on very tight budgets that already have basic spell-checking covered in their office tools.
- Highly specific use cases that require integrations with local systems not supported by the platform.
Key features
- Real-time checker for spelling, grammar, punctuation, clarity, fluency, and tone.
- Sentence-level and full-paragraph rewrites with a single click.
- Tone detector that shows how the text may come across before sending it.
- AI text generation for drafts, replies, outlines, and ideas.
- Inline translation across 19 language variants, without leaving the application where you are writing.
- AI detector and plagiarism checker built into the suite.
- Style guide, reusable snippets, and analytics dashboard for business plans.
- Brand tones to maintain a consistent voice across the whole team.
These features allow an SME to cut review time, avoid mistakes that damage a professional image, and unify the brand voice without hiring outside editors. The difference is especially noticeable in teams that send dozens of emails per day or produce content for several channels.
AI features
Grammarly’s AI layer is organized around its specialized agents. Each one serves a specific purpose and can be invoked from the side panel of the Docs editor or from the browser extension.
Proofreader: continuous correction and review while you write. Paraphraser: adjusts style, tone, and voice, with options such as academic, professional, simple, or humanized, plus the ability to upload a sample to create a personalized voice. Reader Reactions: predicts how the text may land with the audience you define. Citation Finder: searches for sources and generates citations automatically. AI Grader: estimates a grade based on the rubric of the course or document. Humanizer: softens AI-generated text so it sounds more natural. AI Detector and Plagiarism Checker: verify originality and detect AI-generated content. Fact Checker: assesses the strength of arguments against data.
What truly sets it apart are the agents that evaluate the text from different perspectives (the reader’s, the proofreader’s, the grader’s) and the integration with Go, the proactive assistant that appears across any browser-based app. The rest (error correction, tone detection) is already standard in the category, although Grammarly delivers it with above-average polish.
Integrations
Extensions for Chrome, Safari, Firefox, and Edge, covering more than one million websites and web applications. Desktop applications for Windows and Mac that work in Word, Pages, email clients, and practically any application. Add-ins for Microsoft Office and Google Docs. Mobile keyboard for iOS and Android, compatible with Gmail, Outlook, WhatsApp, X, Facebook, Instagram, Snapchat, LinkedIn, iMessage, and Google Messages. Integration with Canvas for reviewing academic work on education plans. Within the Superhuman ecosystem, a connection with Salesforce from Superhuman Mail, Slack, WordPress, Google Drive, Gmail, and Canva.
On API availability: Grammarly offers advanced configurations for Enterprise customers, including SCIM provisioning with Okta and other identity providers, as well as single sign-on through SAML. For general programmatic use, there is no public API for external developers.
Security and data compliance
Grammarly maintains that user data belongs to the user and is never sold. Users can opt out of having their content used to train models, and by default Grammarly does not train on content from certain corporate users or from accounts based in the European Union or the United Kingdom. The company publishes dedicated pages on privacy, security, compliance, and responsible AI in its Trust Center.
The Enterprise plan adds bring-your-own-key encryption (BYOK), data loss prevention, audit logs via API, application and domain controls, custom roles, and granular permissions. Authentication supports SAML for single sign-on and SCIM for automated user and group provisioning. When a user is deactivated in the identity provider, their account remains inactive for 30 days before being fully deleted.
Language – Customer support and interface
Grammarly’s main interface is in English, although the editor automatically recognizes the language of the text and offers suggestions in that same language. The help center is mostly in English. Customer support is handled mainly through email and forms. Higher-tier plans include dedicated support and the option to schedule meetings with a sales or customer success team.
AI language – The tool itself
Grammarly supports writing in 23 languages, including Spanish (Argentina, Mexico, and Spain), English (American and British), Portuguese (Brazil and Portugal), French, German, Italian, Turkish, Polish, Dutch, Czech, Vietnamese, Hungarian, Swedish, Romanian, Indonesian, Slovak, Danish, Finnish, Norwegian, Ukrainian, Korean, Tagalog, and Hindi. Basic correction (the red underlines) is available in all of those languages. Advanced suggestions for grammar, clarity, fluency, and tone, along with paragraph rewrites, are concentrated in English, Spanish, French, German, Portuguese, and Italian.
Mobile access
Grammarly offers dedicated mobile apps for iOS and Android, which install as a system keyboard and work inside any application. On iOS, correction coverage spans 17 languages. On Android it extends to 24 languages for spelling and grammar, and 6 for clarity and fluency. Not every desktop feature is available on mobile, but the experience is enough for replying to emails, drafting messages, and posting on social platforms with real-time assistance.
Support, onboarding, and account management
- Online help center with articles, tutorials, and guides by product and platform.
- Technical, education, and business blogs with use cases and best practices.
- Immediate free signup and the option to try the Pro plan with a trial period.
- Automatic reminders before the end of the trial period.
- For Enterprise plans: dedicated support, customer success manager, live demos, and assisted setup.
- Specific resources for the education plan, with materials for teachers and administrators.
For an SME with little technical experience, the onboarding curve is very short. Just install the extension or the desktop app and suggestions start arriving right away.
Ease of use / UX
The Grammarly experience is one of its biggest selling points. Suggestions appear as color-coded underlines: red for basic corrections, blue for advanced suggestions, and yellow for style, clarity, word choice, tone, or improvements that make the text more fluent and professional. Each suggestion can be accepted or rejected with a click.
For the English test, we ran an excerpt from one of our articles through Grammarly, and it handled the text well, producing clear and fluent rewrites. It is less precise with colloquialisms, regional idioms, or double meanings. The AI chat inside the Docs editor is multilingual.
There are no complicated menus or required settings. An SME can get value from day one: the person writing an email in Gmail or a document in Word sees the recommendations without switching tools. The AI agents open in a side panel and match the visual style of the rest of the suite.

Pricing and plans

Case study
A twelve-person digital marketing consultancy serves clients across Mexico, Colombia, Spain, and the United States. The team uses Superhuman Mail as its primary email client, Salesforce as its CRM, and Grammarly as a review layer across every writing surface.
When an email arrives from a U.S. prospect requesting a proposal, the account manager opens the message in Superhuman Mail, and the sidebar surfaces the Salesforce record with the contact history, the most recent open opportunity, and notes from previous conversations. She drafts the reply directly in English. Grammarly flags a couple of agreement issues, suggests a friendlier tone to open the proposal, and offers a rewrite of the closing paragraph to make it sound more professional. The account manager accepts the changes in seconds and sends the email; Salesforce’s Auto-Bcc address is configured so the conversation is logged automatically to the corresponding opportunity.
Before adopting this workflow, the team spent roughly an hour a day per person reviewing emails, copying and pasting responses into Salesforce, and rewriting English drafts. That time has been cut in half. The consultancy reports faster replies, a CRM that stays current without manual effort, and consistent quality in English communication across the whole team, even among non-native speakers.
Grammarly Review 2026 vs Alternatives
| Tool | Advantages over Grammarly | Disadvantages compared to Grammarly |
|---|---|---|
| Neuroflash | An all-in-one platform for marketing content creation with more than 100 templates, Brand Hub for brand voice, Digital Twins to validate audiences, and performance prediction. | Grammar correction relies on LanguageTool inside the editor; it is not the core. Less cross-platform integration in everyday applications (email, browser, messaging). |
| DeepL Write | A more natural style in rewrites and better native Spanish support, plus fine-grained control over formal and informal tone in long texts. | A smaller integration ecosystem (extensions, mobile apps, connectors). Fewer features for thorough review, AI agents, or collaborative workflows. |
If the priority is solid correction in grammar, style, tone, and clarity across everything that gets written, Grammarly remains the most straightforward choice, especially in English. If the goal is to produce large volumes of marketing content with AI support and audience validation, Neuroflash works as a more specialized alternative for content generation. For those who write a lot in Spanish and value natural stylistic rewrites, DeepL Write is an interesting alternative, although with less application coverage.
