What is Grammarly?
Grammarly is an AI writing assistant that checks grammar, spelling, style, tone, and clarity across any text you write. Founded in 2009 by Max Lytvyn, Alex Shevchenko, and Dmytro Lider, Grammarly serves over 30 million people daily and has become embedded in professional writing workflows across emails, documents, social media, and code.
The browser extension covers nearly every web-based writing surface: Gmail, Google Docs, LinkedIn, Slack, and more. A desktop app handles native applications. The Grammarly Editor provides a dedicated writing environment, and the Business tier adds style guides and team-level controls.
Over time, Grammarly has expanded well beyond grammar correction. The current AI layer handles full sentence rewrites, tone detection, clarity improvements, and GrammarlyGO, a generative AI assistant built for drafting, replying, and summarizing.
How to get started with Grammarly
- 1

Set your goals
Open the Grammarly editor and set your writing goals before you start. You'll choose an Audience (general, expert, or knowledgeable), Formality (formal, neutral, or informal), Intent (inform, describe, convince, or tell a story), and Domain (academic, business, email, and so on). These settings shape every suggestion Grammarly makes.

Review suggestions
As you write, Grammarly underlines issues using a color system: red for grammar and spelling, blue for clarity, green for style. Click any underline to read Grammarly's explanation of the issue, then accept or dismiss the suggestion. You stay in control of every change.

Use GrammarlyGO for drafting
Premium accounts get access to GrammarlyGO, the generative AI layer built into the editor. Click the GrammarlyGO button, describe what you want to write or improve, and it produces a draft. From there you refine it, which is often faster than starting from scratch.

Set up a Business team style guide
Grammarly Business lets you build a style guide specific to your organization, listing preferred terms, words to avoid, and tone guidelines. Once saved, Grammarly flags deviations across every team member's writing. It's the part of the product that makes Grammarly useful at a team level, not just individually.
Who is Grammarly most useful for?
Most teams use it for one of two things: catching errors before they reach a client, or enforcing consistency across a group of writers. The everyday case is someone who drafts a lot of emails and reports in English and wants a background check on grammar, tone, and spelling without breaking their flow.
For non-native English speakers, Grammarly can meaningfully raise the confidence and polish of professional writing. It works quietly, flagging issues without requiring a manual editing pass.
Marketing and content teams get the most out of Grammarly Business, where style guides let you enforce specific terminology, formality levels, and inclusive language standards across every team member's writing. Use Supademo to walk your team through how to configure those style guides so the rules actually get used.
Support, sales, and success teams writing dozens of emails a day are also a natural fit. Volume creates risk. Grammarly catches the mistakes that come with speed.
Four tools come up most often when people are weighing Grammarly against other options.
ProWritingAid goes deeper on long-form writing. It surfaces overused words, repetition, pacing issues, and style patterns across a full document. Most teams use it for book manuscripts and editorial work. Grammarly is a better fit for everyday professional writing where you want fast feedback, not a deep analysis.
Hemingway is a free, offline-focused editor that highlights complex sentences, passive voice, and adverb overuse. It's useful for tightening prose after a draft is done. Grammarly covers more ground and works across every platform; Hemingway is better as a single-purpose revision pass.
Microsoft Editor is built into Word and Outlook and comes free with a Microsoft 365 subscription. The AI grammar features are comparable to Grammarly's basics. The main difference is platform coverage: Grammarly works across far more surfaces outside the Microsoft ecosystem.
LanguageTool is free, open-source, and supports 30-plus languages with solid grammar checking in each. The interface is less polished, but for teams writing primarily in a language other than English, it's the more practical choice. Grammarly is English-first and leans heavily on AI; LanguageTool prioritizes multilingual breadth.
FAQs on Grammarly
Commonly asked questions about Grammarly. Have more? Reach out and our team will be happy to help.
Is Grammarly free?
Grammarly does have a free plan, and it covers basic grammar and spelling across all platforms. Premium ($12/month) adds clarity, tone, and style suggestions plus GrammarlyGO. Business ($15/user/month) adds team style guides and analytics.
Does Grammarly work in Google Docs?
Grammarly does work in Google Docs. The browser extension suggests edits inline as you write. For deeper integration, Grammarly for Google Docs is available as a Google Workspace add-on and adds a sidebar panel alongside your document.
Is Grammarly secure for sensitive content?
Security with Grammarly depends on what you're writing. Grammarly encrypts data in transit and at rest, but text you type with the extension enabled is processed on their servers. For highly sensitive content, legal drafts, medical records, or confidential deals, review Grammarly's privacy policy and, if needed, ask about their enterprise DPA before enabling the extension in those contexts.
Does Grammarly detect AI-generated text?
Grammarly Premium includes both a plagiarism checker and an AI detection feature that flags text likely to have been AI-generated. Worth knowing: AI detection accuracy across tools industry-wide is imperfect, and Grammarly's is no exception. Treat results as a signal, not a verdict.
Can Grammarly help with tone?
Tone detection is one of Grammarly's more practical features. It reads the tone of your writing (friendly, confident, direct, and similar) and surfaces suggestions to bring it in line with what you intended. This matters most in email, where the same sentence can land very differently depending on word choice and phrasing.
Does Grammarly work in email clients?
Grammarly works in the major email clients. The browser extension covers Gmail and Outlook Web. On Windows, Grammarly for Windows integrates with Outlook desktop. On Mac, the desktop app integrates with Mail and other native applications.
