Grammarly has evolved from a grammar checker into a comprehensive AI writing assistant that works across every platform where you write.

What Grammarly Does

Grammarly provides four layers of writing assistance:

1. Correctness: Grammar, spelling, punctuation errors
2. Clarity: Wordy sentences, unclear phrasing, passive voice
3. Engagement: Vocabulary variety, compelling language, reader interest
4. Delivery: Tone detection, formality level, confidence

Setting Up Grammarly Everywhere

Install Grammarly where you write:

• Browser extension: Chrome, Firefox, Safari, Edge — works on Gmail, Google Docs, social media, CMS platforms
• Desktop app: Standalone writing editor with full feature access
• Mobile keyboard: iOS and Android for on-the-go writing
• Microsoft Office: Add-in for Word, Outlook, PowerPoint
• Slack & Teams: Real-time suggestions in workplace messaging

Understanding the Dashboard

Your Grammarly dashboard shows:

• Overall score: 0-100 rating of your writing quality
• Goals: Set audience, formality, domain, tone, and intent
• Performance stats: Weekly writing statistics and improvements
• Tone detector: Real-time analysis of how your writing sounds

Setting Writing Goals

Before writing, configure goals for context-aware suggestions:

• Audience: General, Knowledgeable, or Expert
• Formality: Informal, Neutral, or Formal
• Domain: Academic, Business, General, Email, Creative
• Tone: Specify desired tones like confident, friendly, diplomatic
• Intent: Inform, Describe, Convince, Tell a Story

Setting Up Grammarly in Microsoft 365 — Step by Step

Many users install the browser extension and miss the deeper integrations. To unlock Grammarly inside Microsoft Word:

1. Open Word → Insert → Add-ins → Get Add-ins
2. Search "Grammarly for Microsoft Word and Outlook"
3. Click Add → Grammarly sidebar appears on the right
4. Sign in with your Grammarly account
5. Suggestions now appear inline as you type

This matters because Word documents — proposals, contracts, reports — are where writing mistakes carry the highest professional cost.

Best Practice — Set Goals Before Every Document

The single highest-leverage Grammarly habit is opening the Goals panel (the target icon) before you write a single word. A client email set to "Formal + Confident + Inform" will receive completely different suggestions than the same email set to "Informal + Friendly + Convince." Users who skip this step and use Grammarly's defaults often find the suggestions feel generic or off-tone.

Common Pitfall — Accepting Every Suggestion

Grammarly is a suggestions engine, not an authority. It frequently flags passive voice in contexts where passive voice is deliberately chosen for diplomacy ("Mistakes were made" in a sensitive HR email is intentional). Review each suggestion category independently and build your own override list for phrases Grammarly mis-flags in your industry.
