What you'll need

Grammarly account (free tier works for most tasks)
Grammarly browser extension or desktop app installed

Install the browser extension

Download the Grammarly extension for Chrome or Edge. It activates automatically in Gmail, Outlook, LinkedIn, Google Docs, and most text editors.

Set your goals before writing

Click the Grammarly icon and set your document goals: Audience (General / Expert), Formality (Informal / Formal), Domain (Business / Academic / Creative).

💡 Tip: Business + Expert + Formal is the right setting for most professional emails and reports.

Review the red and yellow underlines

Red = spelling/grammar errors. Yellow = style suggestions. Work through reds first (critical), then yellows (optional improvements).

Use the 'Improve It' rewrite feature

Highlight any sentence that feels clunky and click 'Improve It'. Grammarly rewrites the sentence while preserving your meaning. Review before accepting.

Check the overall score

The sidebar score (0–100) reflects correctness, clarity, engagement, and delivery. Aim for 90+ on important documents.

💡 Tip: The free tier shows a score but Premium explains why it's lower and how to fix it.

Use tone detection for emails

Grammarly's tone indicator shows how your message will land (e.g., 'Direct', 'Confident', 'Formal'). Adjust wording if the detected tone doesn't match your intent.

Pro Tips

Use Grammarly's 'Snippets' feature to save frequently used phrases like disclaimers or sign-offs.
Enable 'Clarity-focused' rewrites if your first draft is over 20 words per sentence on average.
For long documents, use the desktop app instead of the browser extension — it handles large files better.
