Grammarly is the kind of tool that most people start using before they fully understand what it does. You install the browser extension because a colleague recommended it, and suddenly every text field on the web has a green circle in the corner that counts your errors. The basic experience is intuitive. But beneath the surface — particularly when evaluating Grammarly for a team or an entire organization — there are questions that the product page does not answer clearly enough. Questions about what happens to your data. Questions about which platforms the tool actually works on. Questions about how to get 50 or 500 people using it without creating an IT support nightmare.
This article answers the most common questions we encounter about Grammarly, organized into the categories that matter most for purchase decisions: security and privacy, platform integrations, team onboarding, GrammarlyGO, and pricing.
Background
Grammarly was founded in 2009 by Alex Shevchenko and Max Lytvyn in Ukraine. The company is headquartered in San Francisco. It is one of the world’s largest AI writing assistants, with over 30 million daily active users. In 2021, Grammarly was valued at approximately $13 billion following a $200 million funding round. The product is available across browsers, desktop, mobile, and office suite integrations. Its features include grammar and spelling correction, tone detection, clarity suggestions, plagiarism detection, brand tone guidelines, custom style guides, and generative AI through GrammarlyGO. Competitors include Hemingway Editor, ProWritingAid, DeepL Write, LanguageTool, and QuillBot.
Security and Privacy
Does Grammarly read everything I type?
Grammarly processes the text you type in order to provide suggestions. When the browser extension or desktop app is active, the text in the current text field is sent to Grammarly’s servers for analysis. This is necessary because the AI models that power the suggestions run on Grammarly’s infrastructure, not locally on your device.
However, Grammarly does not process text in fields where the extension is disabled. You can disable Grammarly on specific websites, in specific applications, or in specific text fields. Password fields are excluded by default. For users concerned about specific sensitive contexts — banking sites, confidential internal tools — disabling the extension on those sites is straightforward.
Is my text stored on Grammarly’s servers?
According to Grammarly’s privacy policy, text is processed for the purpose of providing writing suggestions and is stored only as long as necessary to deliver the service. For free and Premium users, text may be used in aggregate to improve the product, though Grammarly states that individual documents are not shared with third parties.
For Enterprise customers, Grammarly provides a stronger guarantee: enterprise customer data is not used to train or improve Grammarly’s AI models. This is a critical distinction for organizations handling sensitive information.
What security certifications does Grammarly hold?
Grammarly Enterprise offers:
- SOC 2 Type II certification: This is an independent audit confirming that Grammarly’s systems and processes meet established standards for security, availability, and confidentiality.
- HIPAA compliance options: For healthcare organizations subject to HIPAA regulations, Grammarly Enterprise can sign a Business Associate Agreement (BAA) that establishes HIPAA-compliant data handling.
- Data encryption: Text is encrypted in transit using TLS and at rest using AES-256 encryption.
- Regular penetration testing and security audits: Conducted by third-party firms.
Can we self-host Grammarly?
No. Grammarly is a cloud-based service. There is no on-premises or self-hosted deployment option. Organizations with strict data residency or air-gapped network requirements cannot use Grammarly. For these use cases, alternatives like LanguageTool (which offers a self-hosted server option) may be more appropriate.
Does Grammarly comply with GDPR?
Yes. Grammarly complies with the General Data Protection Regulation (GDPR) for users in the European Union. Users can request data export and deletion through Grammarly’s account settings. Grammarly’s privacy policy and data processing agreements address GDPR requirements for enterprise customers.
What about data residency?
Grammarly’s infrastructure is primarily hosted in the United States. For organizations with data residency requirements that mandate data remain within specific geographic boundaries (such as the EU or specific countries), this may be a limitation. Grammarly does not currently offer regional data hosting options.
Platform Integrations
Which browsers does Grammarly support?
Grammarly offers browser extensions for:
- Google Chrome
- Microsoft Edge
- Mozilla Firefox
- Apple Safari
The Chrome extension is the most feature-complete and is updated most frequently. The Edge extension mirrors Chrome functionality closely. Firefox and Safari extensions are supported but may occasionally lag behind in feature parity.
Which desktop applications does Grammarly support?
- Grammarly for Windows: A standalone desktop application that monitors text across all Windows applications
- Grammarly for macOS: A standalone desktop application that works across macOS applications
- Microsoft Word integration: A dedicated add-in that provides Grammarly suggestions directly within Word
- Microsoft Outlook integration: Available through the desktop app and browser extension
- Google Docs: Supported through the browser extension, with deep integration for suggestions, comments, and GrammarlyGO
Does Grammarly work on mobile?
Yes. Grammarly offers:
- Grammarly Keyboard for iOS: A custom keyboard that provides suggestions across all iOS apps
- Grammarly Keyboard for Android: A custom keyboard for Android devices
- Grammarly for iPad: The keyboard and iPad app provide suggestions in tablet contexts
The mobile experience is more limited than desktop — fewer suggestion categories, less detailed tone analysis — but core grammar, spelling, and punctuation checking works reliably.
Does Grammarly work with Google Workspace?
Yes. Grammarly works with:
- Google Docs: Full integration through the browser extension, including GrammarlyGO
- Gmail: Suggestions appear directly in the compose window
- Google Slides: Basic suggestions through the browser extension (more limited than Docs support)
Does Grammarly work with Slack?
Yes, through the browser extension (in Slack’s web client) and through the desktop app (which can monitor the Slack desktop application). Suggestions appear inline as you type messages.
Does Grammarly work with Notion, Confluence, or other wiki tools?
Grammarly’s browser extension works in most web-based editors, including Notion, Confluence, and similar tools. The quality of integration varies depending on the text editor framework used by each platform. In some editors, Grammarly’s suggestions may not appear inline and instead require opening the Grammarly sidebar.
Which platforms does Grammarly NOT work well with?
Grammarly has limited functionality in:
- Code editors: VS Code, IntelliJ, and similar development environments are not supported (Grammarly is designed for natural language, not code)
- Some custom web editors: Websites using non-standard text input frameworks may not trigger Grammarly’s suggestions
- Encrypted or DRM-protected documents: Text that cannot be read by the browser extension cannot be checked
Team Onboarding
How do we deploy Grammarly to a team?
For Grammarly Business (small to mid-size teams):
- Purchase a Grammarly Business plan through the admin console
- Add team members by email invitation
- Each team member creates or connects a Grammarly account
- Team members install the browser extension and/or desktop app
- The admin configures the style guide and brand tone guidelines
For Grammarly Enterprise (large organizations):
- Work with Grammarly’s sales team to establish a contract
- Configure SAML SSO so team members authenticate through the organization’s identity provider
- Set up SCIM directory sync to automate user provisioning and deprovisioning
- Distribute the browser extension through managed browser policies (Chrome Enterprise, Edge management, etc.)
- Configure style guide, brand tone, and GrammarlyGO settings through the admin console
Can we push the browser extension through managed deployment?
Yes. Grammarly provides documentation for deploying the Chrome extension through Google Admin Console (for Chrome Enterprise) and through Microsoft Endpoint Manager or Group Policy for Edge. IT administrators can install the extension silently on all managed devices, preconfigure settings, and prevent users from uninstalling it.
How long does onboarding typically take?
For a Business deployment of 10 to 50 users, the process typically takes 1 to 2 weeks from purchase to full adoption. This includes admin setup (1 to 2 days), user invitations and installations (3 to 5 days for all users to activate), and style guide configuration (ongoing, but an initial version can be ready in 2 to 3 days).
For Enterprise deployments of 100+ users with SSO and SCIM integration, the timeline extends to 4 to 8 weeks, depending on the complexity of the identity provider integration and internal security review processes.
What training do team members need?
Minimal. Most users are familiar with Grammarly from personal use. A 30-minute orientation covering the following topics is typically sufficient:
- How the style guide and brand tone affect their suggestions
- How to use GrammarlyGO for drafting and rewriting
- How to disable Grammarly on specific sites or in specific contexts
- Where to find the settings panel to customize personal preferences
Can we track adoption and usage?
Yes. The Grammarly Business and Enterprise admin console provides metrics including:
- Number of active users
- Number of suggestions generated and accepted
- Communication clarity scores by team and department
- Tone consistency metrics
- Most triggered style guide rules
These metrics are valuable for demonstrating ROI and identifying teams that may need additional encouragement or training.
GrammarlyGO
What is GrammarlyGO?
GrammarlyGO is Grammarly’s generative AI feature, launched in April 2023. It uses large language models combined with Grammarly’s proprietary NLP to compose, rewrite, and brainstorm within the Grammarly interface. GrammarlyGO works directly in the contexts where you write — Gmail, Google Docs, Microsoft Word, Slack, and other supported platforms — rather than requiring a separate app or website.
What can GrammarlyGO do?
- Compose: Generate new text from a brief prompt. For example, “Write a follow-up email thanking the client for the meeting and proposing next steps.”
- Rewrite: Select existing text and ask GrammarlyGO to make it shorter, longer, more formal, more casual, or adjusted to a specific tone.
- Reply: In email contexts, GrammarlyGO can generate a reply based on the content of the received message.
- Brainstorm: Generate ideas, outlines, or alternative approaches for a topic.
- Summarize: Condense long text into key points or a brief summary.
Does GrammarlyGO use my organization’s style guide and brand tone?
Yes, for Business and Enterprise plans. GrammarlyGO-generated text respects the organization’s configured brand tone guidelines and style guide rules. This means generated content automatically uses preferred terminology, avoids banned phrases, and matches the target tone.
How many GrammarlyGO prompts do I get?
Usage limits vary by plan:
- Free: A limited number of prompts per month (the exact number varies and may change)
- Premium: A significantly higher monthly allocation
- Business: Higher allocation per user with team-level management
- Enterprise: Custom limits negotiated as part of the contract
The specific numbers are not publicly fixed and have been adjusted over time. Check Grammarly’s current pricing page for the latest allocations.
Is GrammarlyGO as good as ChatGPT or Claude for writing?
GrammarlyGO is not designed to replace general-purpose AI chatbots. Its strengths are contextual integration (it works inside your email, document, or chat rather than in a separate interface), brand voice alignment (it follows your organization’s tone and style settings), and focused writing tasks (composing, rewriting, replying). For open-ended creative writing, research, or complex reasoning, general-purpose AI tools are more capable. For day-to-day professional writing tasks within your existing workflow, GrammarlyGO is more convenient.
Pricing Questions
How much does Grammarly cost?
- Free: $0 — grammar, spelling, punctuation, basic suggestions
- Premium: Approximately $12 per month (annual billing) or $30 per month (monthly billing)
- Business: Approximately $15 per user per month (annual billing), minimum 3 users
- Enterprise: Custom pricing — contact Grammarly sales
Is there a discount for annual billing?
Yes. Annual billing provides significant savings over monthly billing. Premium drops from approximately $30/month to $12/month with annual billing — a roughly 60 percent discount. Business plans are typically billed annually by default.
Can I try Premium before buying?
Grammarly occasionally offers free trials of Premium features. The Free plan itself serves as a permanent trial of the core product. For Business and Enterprise evaluations, Grammarly’s sales team can arrange pilot programs for teams.
Is Grammarly worth it for students?
Grammarly offers student discounts periodically, though they are not always publicly advertised. For students who write regularly in English — particularly non-native speakers and students in writing-intensive programs — Premium’s clarity suggestions, full-sentence rewrites, and plagiarism detection provide meaningful value. The Free plan is a strong starting point for students on a tight budget.
Can we cancel at any time?
Monthly plans can be canceled at any time; the subscription remains active until the end of the current billing period. Annual plans can be canceled, but refunds for unused months are generally not provided. Grammarly’s refund policy may offer exceptions within a short window after purchase — check the current terms of service for details.
How does Grammarly compare in price to alternatives?
| Tool | Individual Price | Team Price |
|---|---|---|
| Grammarly Premium | ~$12/mo | N/A |
| Grammarly Business | N/A | ~$15/user/mo |
| ProWritingAid | ~$10/mo (annual) or $399 lifetime | Limited team features |
| LanguageTool Premium | ~$4.99/mo | Negotiable |
| QuillBot Premium | ~$4.17/mo (annual) | No team plan |
| Hemingway Editor | $19.99 one-time | No team plan |
| DeepL Pro (incl. Write) | ~$8.74/mo | Team plans available |
Grammarly is not the cheapest option in any category. Its pricing reflects the breadth of features, depth of platform integration, and maturity of enterprise capabilities. Whether the premium is justified depends on which features you actually use.
Conclusion
Most questions about Grammarly boil down to a simple framework: Does the tool do what I need, can I trust it with my data, and is it worth the cost?
On capability, Grammarly is the most comprehensive AI writing assistant available, with the widest platform coverage and the most developed enterprise feature set. On security, the Enterprise tier meets the requirements of most regulated industries, though the lack of self-hosted or regional hosting options limits its suitability for organizations with the strictest data residency requirements. On cost, Grammarly is priced at a premium relative to alternatives, but the premium buys integration depth, enterprise features, and a generative AI capability that most competitors have not matched.
The practical recommendation is to start with the Free plan, evaluate whether the limitations actually affect your work, and upgrade only when they do. For teams, start with a pilot of Grammarly Business for the department where writing quality matters most, measure the impact, and expand based on data rather than assumption. The tool sells itself when it is actually used; the challenge is not convincing people it is good but ensuring it is configured and adopted in a way that delivers the value it is capable of.
