Grammarly Chrome extension

Grammarly checks grammar, spelling, punctuation, and tone in real time across most websites, including Gmail, Google Docs, and LinkedIn. It's best for anyone who writes online often and wants quick corrections. The catch: advanced rewrites, plagiarism detection, and team features require the paid Pro plan.

What Grammarly does

Grammarly runs in the background as you type on supported websites, checking your text for grammar, spelling, and punctuation issues and suggesting tone adjustments. It works across most sites, including Gmail, Google Docs, and LinkedIn, and can also help draft or outline content using AI.

Grammarly free vs paid

The free plan covers essential grammar, spelling, and basic clarity suggestions, which is enough for everyday writing. The paid Pro plan adds sentence rewrites for flow and engagement, plagiarism detection, auto-citations, and team collaboration features for users who write more formally or professionally.

Is Grammarly safe?

Because Grammarly checks text as you type, its permissions include reading website content and, on some sites, personal information you enter, which is necessary for the correction feature to work. Review what you're comfortable typing into forms with Grammarly active, particularly on sites handling sensitive data.

Does Grammarly check tone?

Can Grammarly detect plagiarism for free?
