Your first ten minutes with Grammarly: sign up free, install it where you write, set your writing goals, and review every suggestion. Includes the Free vs Pro breakdown.

Learning how to use Grammarly takes about ten minutes: you sign up for a free account, install it where you already write, tell it what kind of writing you are doing, and then review its suggestions one by one. Grammarly is an AI-powered writing assistant that checks your grammar, spelling, and punctuation and suggests clearer, more confident wording — wherever you type. It is not a search engine and not a fact-checker; it polishes your words, but the thinking and the facts still have to come from you. Before you paste in anything important, a quick check of your draft's length with a free word counter can save you from hitting document-size limits.

How do you use Grammarly?

Grammarly watches what you type and underlines anything it thinks could be better — a misspelled word, a comma splice, a wordy sentence. You click each underline, read the suggestion, and accept or dismiss it. That is the whole loop:

1. Sign up at grammarly.com with your email (or a Google, Apple, or Facebook account) — the free plan costs nothing.
2. Install it where you write: the browser extension for Chrome, Edge, Firefox, or Safari; the desktop app for Windows or Mac; the mobile keyboard for iPhone or Android; or the Microsoft Office add-in for Word.
3. Set your goals — audience, formality, and tone — so Grammarly's suggestions match the writing you are doing.
4. Write as normal. Grammarly underlines issues as they appear; you accept or dismiss each one.
5. Review, don't rubber-stamp. Grammarly is highly effective but never 100 percent right — read every suggestion before accepting it.

Which way of using Grammarly should you pick?

Grammarly is the same assistant wearing different outfits. Pick the outfit that matches where you actually write — most beginners start with the browser extension, because it covers email, documents, and social posts in one install:

Install the extension from your browser's extension store, pin it to the toolbar, and sign in — from that point on it works silently in the background. The desktop app and Office add-in install the same way as any ordinary program: download, run the installer, and sign in when it asks. You can use Grammarly on several surfaces at once; the suggestions follow your account, not your device.

How do you set up Grammarly for the first time?

The setup that matters most is not the install — it is the goals. Grammarly suggests very different wording for a job application than for a text message, and it only knows which you are writing if you tell it:

1. Create the account. Go to grammarly.com, enter your email and a password, and verify the email. Sign-up with a Google, Apple, or Facebook account also works.
2. Install one surface. Start with the browser extension; you can add the desktop app or Office add-in later.
3. Open the goals. In the editor or sidebar, click Set Goals (or the equivalent goals button on your surface).
4. Choose your audience, formality, tone, and domain. A college essay gets Formal and Academic; a birthday note gets Informal. These settings steer every suggestion Grammarly makes.
5. Write a paragraph and accept a few suggestions. Click an underline, read the short explanation, and accept or dismiss it. Dismissing teaches Grammarly your preferences.

One practical note: keep your account's email current. Grammarly's verification and password-reset messages go there, and losing access to that inbox is the most common way people get locked out of their own documents.

How do Grammarly's suggestions actually work?

As you type, Grammarly scans the sentence and underlines anything it flags — different colors mark different kinds of issues, such as spelling, grammar, or style. Clicking an underline opens a small card with the suggested change and a short reason, for example why a comma belongs there or why a sentence is hard to follow.

Three rules keep the suggestions useful instead of annoying:

• Read the card, not just the underline. The explanation is the part that teaches you the rule, so the same mistake stops recurring.
• Dismiss what you meant. Jargon, names, brand terms, and deliberate style choices will get flagged. Use the dismiss option (and the custom dictionary for repeated words) instead of fighting the tool.
• Never auto-accept on an important document. Grammarly catches grammar and spelling, not factual accuracy or tone-deaf wording. On a resume, an application, or a contract, read every suggestion before you accept it.

Grammarly also needs an internet connection to work: the analysis runs on Grammarly's servers, so it does not check your writing offline. Plan your editing for when you are connected.

What does the Goals feature do?

Goals are the difference between Grammarly acting like a copyeditor and acting like a proofreader. Before you write — or when you open an existing document — you set four things:

• Audience: who is reading (general, knowledgeable, or expert).
• Formality: informal, neutral, or formal.
• Tone: friendly, confident, diplomatic, and similar — what feeling the writing should carry.
• Intent and domain: whether you are informing, persuading, telling a story, and what kind of document it is (academic, business, email, and so on).

Grammarly then weights its suggestions: formal + academic steers it toward precise wording and stricter rules, while informal + friendly lets casual phrasing pass. If the suggestions feel wrong for the piece you are writing, check the goals before blaming the tool — a mismatch there is the usual cause. Writers who want to get better at shaping prompts for any AI tool can go deeper with our guide to write better AI prompts; the briefing habit it teaches applies to Grammarly's goals just as much as to chatbots.

What is the difference between Grammarly Free and Pro?

Grammarly's free plan is genuinely free — no credit card, and it covers the corrections most beginners need. Pro (formerly Premium) adds the deeper rewrites, tone control, and plagiarism checking. Here is what each tier includes, based on Grammarly's current public pricing pages checked on October 29, 2026:

Start free. Most students and everyday writers never outgrow it; upgrade only when you find yourself repeatedly wanting the rewrites, the tone controls, or the plagiarism check. Prices and prompt limits change over time, so treat the figures above as the October 2026 snapshot, not a permanent quote.

What should you not use Grammarly for?

Grammarly is a writing polisher, not a writing authority. Keep four boundaries in mind:

• It does not check facts. A perfectly grammatical sentence can still be completely wrong. Verify names, numbers, dates, and claims yourself.
• It does not understand nuance. Sarcasm, deliberate fragments, legal wording, and creative choices will get "corrected." You are the author; the tool is the intern.
• Think before pasting sensitive text. Grammarly sends your text to its servers to analyze it. Grammarly states that it does not sell user data, use it for advertising, or let third parties use it to train their models — but confidential work, passwords, and personal records do not belong in any online checker. Format or review such files locally first.
• It will not make you a better writer by itself. The explanations on each suggestion card are the learning mechanism. Skim them and you improve; blindly accept and you outsource your judgment.

Students are the biggest audience here: Grammarly is excellent for cleaning up a college essay draft, but the ideas, structure, and honesty of the essay still have to be yours. And if you type for a living, knowing what counts as a good typing speed helps you judge whether slow output or constant re-editing is your real bottleneck.

Frequently Asked Questions

Is Grammarly free?

Yes — the free plan costs $0 and includes spelling and grammar corrections plus tone detection, with no credit card required. The paid Pro plan adds full-sentence rewrites, tone adjustments, plagiarism checking, and far more AI prompts.

How do I install Grammarly on Chrome?

Open the Chrome Web Store, search for Grammarly, and add the extension to your browser. Pin it to the toolbar, sign in with your Grammarly account, and it will start checking your writing on supported sites immediately.

Does Grammarly work in Microsoft Word and Google Docs?

Yes. Install "Grammarly for Microsoft Office" for Word on Windows or Mac, which adds a Grammarly sidebar inside Word. In Google Docs, the Grammarly browser extension provides the checks directly in the document.

Can Grammarly check for plagiarism?

Plagiarism checking is a Pro feature, not part of the free plan. It compares your text against web pages and academic databases and flags passages that match — useful for students and writers who need originality checks.

Does Grammarly work offline?

No. Grammarly analyzes your text on its servers, so it needs an internet connection to function. Draft offline if you like, but the checks only run once you are connected.
