Grammarly Browser Extension

What the Grammarly browser extension does

The Grammarly Chrome extension is an always-on writing assistant that works inside compatible text fields. It checks grammar, spelling and punctuation while you type, then adds suggestions for clarity and tone. The same product is also available from Microsoft Edge Add-ons and Firefox Add-ons, so this guide keeps all three official store links together instead of presenting them as separate tools.

Grammarly is useful when you write email, documents, social posts, support replies or business messages in a browser. It is more than a basic spell checker: the official listings describe sentence rewrites, tone changes, drafting, outlining, citations and AI-assisted content generation. Features vary by plan, and the extension still leaves the final decision to the writer.

• Real-time grammar, spelling and punctuation feedback

• Clarity and tone suggestions with explanations

• AI brainstorming, drafting and rewriting tools

How to install Grammarly in Chrome, Edge and Firefox

For Chrome, open the Chrome Web Store link at the top of this page and choose Add to Chrome. For Firefox, open Firefox Add-ons and choose Add to Firefox. For Edge, open Microsoft Edge Add-ons, choose Get, and then confirm Add extension. After installation, sign in or create a Grammarly account when the extension asks. Chrome users can open the Extensions menu and pin Grammarly so its icon remains visible on the toolbar.

• Use only the official store button for the browser you are currently using.

• Review the permission prompt before confirming the installation.

• If the icon is hidden in Chrome, pin it from the Extensions menu.

How to check grammar, spelling and punctuation

Open a supported website and start typing in a text field. Grammarly normally places its status icon near the lower-right corner of that field and marks detected issues with underlines. Select an underline or open the suggestion card to read the proposed change and its explanation. Accept a useful correction, dismiss a suggestion that does not fit the context, or add a valid name or specialist term to your personal dictionary.

• Read the complete sentence before accepting a change.

• Dismiss suggestions that alter a technical meaning or proper name.

• Use the personal dictionary for recurring terms that are intentionally spelled that way.

How to use clarity, tone and rewriting suggestions

Clarity suggestions focus on wording that may be difficult to read, while tone tools help adapt a message to its audience. Open the Grammarly card, review the rewritten version and compare it with the original before selecting Accept. The official material shows actions such as Improve, Rephrase and Shorten, plus instructions that can make a message sound friendlier or more professional. These are editing proposals, not guaranteed facts, so names, dates, numbers and commitments still need manual review.

• Use clarity edits to remove unnecessary words or awkward phrasing.

• Use tone controls to match a professional, friendly or formal audience.

• Keep factual details under human review after any rewrite.

How to use Grammarly AI

The official help material describes a green lightbulb entry for generative AI features. Open it where available, state the result you want, and provide enough context for the draft or rewrite. Typical tasks include creating an outline, brainstorming ideas, drafting an email and rewriting selected text. Treat the generated result as a first draft: verify facts, remove private information that should not be shared, and edit the wording so it represents your own intent.

• Give the AI a concrete audience, purpose and desired tone.

• Select only the text that needs rewriting when possible.

• Check citations, claims and confidential details before using the result.

Grammarly Free versus Pro

The official browser listings say the Free plan includes grammar, spelling and punctuation checks, suggestions for clarity and tone, automatic citations in APA, MLA or Chicago style, and some AI help for brainstorming, drafting and rewriting. Pro adds broader sentence rewrites, tone and formality controls, word-choice improvements, audience insights, feedback for academic, technical or professional work, plagiarism detection, AI-content checks and team features such as style guides. Availability and limits can change, so confirm the current plan page before purchasing.

• Start with Free if the main need is correction and occasional rewriting.

• Consider Pro only when advanced rewrites, originality checks or team controls are required.

• Check current quotas and regional pricing on Grammarly before subscribing.

Supported sites and practical use cases

Grammarly says its browser integration works across more than 500,000 apps and websites, and the official listings specifically mention Gmail, Google Docs and LinkedIn. The store screenshots also show Outlook, Slack, Confluence, Zendesk, X, Facebook and other writing surfaces. Compatibility can differ by editor and account, so test the exact site you rely on before treating the extension as part of a critical workflow.

• Email: review spelling, tone and clarity before sending.

• Documents: outline, draft and revise longer text in Google Docs.

• Professional networks and support tools: adapt short messages for the intended audience.

Settings, privacy and common questions

Open the Grammarly extension settings to manage behavior for individual websites and review options such as definitions and synonyms, language preferences, keyboard shortcuts, AI features and automatic citations. If suggestions interfere with a particular editor, disable Grammarly on that site instead of uninstalling it everywhere. Because a writing assistant can operate across many text fields and requests broad site access, review the permission prompt, Grammarly privacy policy and trust documentation before using it with confidential, legal, financial or personal information.

How do you use Grammarly on Google Docs? Install the browser extension, sign in, open a document and use the Grammarly indicator and suggestion cards while editing. How do you use Grammarly for free? Choose the Free plan and use the included corrections and available AI features within the current limits. Does the browser extension add Grammarly to desktop Microsoft Word? No: Grammarly directs users who need Word, Outlook, Slack and other desktop apps to its separate Windows or Mac desktop product.

• Use the website-specific switch when one editor is incompatible.

• Read the privacy policy before entering sensitive text.

• Use the desktop product, not the browser extension, for desktop Word integration.
