Grammarly

What it does

Grammarly runs inside the browser, Word and Outlook, so it corrects buyer emails and quotations as they are written rather than after the fact. Tone detection is the useful part for export: it flags a reply that reads curt or over-familiar before it reaches a buyer.

The free tier covers grammar and spelling. Rewrites, tone adjustment and plagiarism checks sit behind the paid plans.

Standout features

• Inline grammar and spelling correction
• Tone detection for buyer-facing emails
• Works in Gmail, Outlook and Word
• Brand tone and style guides on team plans
• Plagiarism check on paid tiers
