Grammarly is an AI writing assistant that checks your spelling, grammar, clarity, and tone as you type. It works in your browser, in documents, and on your phone, so mistakes get caught where you send the message. This guide shows you how to set it up free, fix your first draft, and decide whether the paid plan is worth it.
What Is Grammarly?
Grammarly reviews your writing in real time and underlines possible problems. Click a suggestion to accept it or dismiss it — it never rewrites your whole text unless you ask it to. The free plan covers core spelling and grammar checks, shows the tone of your writing, and includes 100 AI prompts a month for generating or improving text. It fits students and daily email writers, and sits well alongside our guide to the best free AI tools for students in 2026
.
Unlike a chatbot, Grammarly needs no separate conversation: the checks appear where you normally write, so it protects the final version, not just a draft in another tab.
Step 1: Sign Up Free and Add It Where You Write
Go to grammarly.com and create a free account with your email or a Google login. The free plan costs nothing and, according to Grammarly, you can use it for as long as you like.
Next, add Grammarly where you write most: the browser extension for Chrome or Edge, and the Grammarly Editor at app.grammarly.com for longer documents. On your phone, add the Grammarly keyboard for iPhone or Android.
Step 2: Fix Your First Draft With Underlines
Open a real piece of writing — an email, a cover letter, or a short essay — where the extension is active or in the Editor. Grammarly underlines spelling and grammar problems, and you can work through the suggestions one by one.
Read each suggestion before accepting it. If a word is correct — a name or technical term — dismiss it or add it to your dictionary. Reading each suggestion teaches you the rule behind it, and accepting Grammarly's shorter versions of wordy sentences quickly improves your writing.
Step 3: Use AI Prompts Without Losing Your Voice
The green lightbulb icon opens Grammarly's AI features. Ask it to improve a paragraph, shorten it, make it more formal, or generate a first draft from a short prompt. Each request uses one of your 100 free AI prompts for the month, so spend them on real work, not testing.
Draft first, then improve. Write your own rough version, ask Grammarly to improve it, and compare it with your original before accepting. Our guide onhow to write better AI prompts explains the same principle: a clear instruction, some context, and one round of editing beats a vague request. If a rewrite sounds unlike you, try a smaller change, such as "make this sentence clearer."
Step 4: Check Tone Before You Send
Grammarly shows the tone of your writing on the free plan — for example, whether a message sounds confident, friendly, or formal. Changing the tone and rewriting full sentences to match it is a Pro feature. Before sending an important email, read the tone label and ask whether it matches the reader.
Plagiarism checks and AI-text detection are also Pro features, useful if you publish work. Regular publishers, as our guide to the best free AI tools for content creators in 2026 describes, may find them worth the upgrade; for everyday emails, most beginners do not need them.
Free vs Pro: Which Plan Fits You?
Grammarly Free costs $0 and covers core checks, tone detection, and 100 AI prompts a month. Grammarly Pro is listed at $12 per member per month when billed annually, and adds full-sentence rewrites, tone adjustment, plagiarism and AI-text detection, and 2,000 AI prompts per member per month. Prices can change, so check grammarly.com/plans before you upgrade.
Stay on Free if you mainly want mistakes caught and use AI features occasionally. Upgrade to Pro if you write all day or need plagiarism checks for published work. Try Free for two weeks first and count how many times it catches something you would have sent.
Avoid these beginner mistakes: accepting every suggestion unread; letting AI rewrites replace your own draft; ignoring the tone label on important messages; burning your 100 free prompts on day one; and assuming Grammarly understands context it cannot see, such as a joke between friends.

Grammarly works best as a quiet second pair of eyes: it catches typos, tightens wordy sentences, and flags unintended tone. Start free, and upgrade only when your volume demands it. Which part of your writing do you want Grammarly to help with first — emails, essays, or social posts? Tell us in the comments.
