Grammarly

by Grammarly

BeginnerFreemiumFree plan available; Pro from $12/month

An AI writing assistant that works as a browser extension and desktop app, adding an overlay to every text field you type in — emails, documents, social media posts, and more. As you write, Grammarly underlines issues and suggests corrections for grammar, spelling, style, and tone in real time. You click suggestions to accept them. Its GrammarlyGO feature lets you generate or rewrite text with AI prompts directly in your writing flow.

What is Grammarly?

Grammarly is an AI-powered writing assistant that sits quietly in the background and improves everything you type — emails, reports, social media posts, even messages. It goes far beyond a basic spell checker: it picks up awkward phrasing, suggests stronger word choices, and tells you whether your tone sounds too blunt or too casual for the situation.

The browser extension and desktop app mean it works in Gmail, Word, Google Docs, LinkedIn, and almost anywhere else you write online.

Best Use Cases

Professional Emails

Grammarly is brilliant for anyone who writes a lot of work emails. It flags unclear sentences, suggests a more confident tone, and catches those embarrassing typos before you hit send.

Try enabling tone detection: Set your goal to "Formal" and "Informative" and Grammarly will flag any language that sounds too casual or abrupt for a professional context.

Reports and Documents

When you are writing something longer — a project report, a proposal, or a business plan — Grammarly's suggestions help maintain consistent style throughout and flag passive voice or convoluted sentences.

Try this: Paste a paragraph you are unsure about into grammarly.com and click "Improve it" using GrammarlyGO to see a rewritten version in your chosen tone.

Social Media and Marketing Copy

Grammarly helps you punch up social media captions and marketing copy — tightening sentences, removing filler words, and making sure your message lands clearly.

Try this prompt in GrammarlyGO: "Rewrite this caption to sound more engaging and energetic, under 50 words."

Getting Started

  1. Go to grammarly.com and create a free account.
  2. Install the browser extension for Chrome, Firefox, Safari, or Edge — this is the easiest way to use Grammarly everywhere.
  3. Open any email or document and start typing. Grammarly's suggestions appear as underlined text — click any suggestion to accept or dismiss it.
  4. For a deeper review, paste your text into the Grammarly Editor at grammarly.com for a full document analysis.

Tips for Beginners

  • Set your goals before writing. Click "Goals" in the Grammarly Editor to tell it your audience, tone, intent, and domain — the suggestions become much more relevant.
  • Don't accept every suggestion blindly. Grammarly is very good but not perfect. Sometimes your original phrasing is better, especially in creative writing.
  • Use GrammarlyGO for rewrites. The free tier includes limited AI rewrite credits. Use them on your trickiest paragraphs rather than routine text.
  • The free version covers the essentials. Grammar, spelling, and basic clarity checks are all free. Premium adds style, tone, and plagiarism features.
