Productivity & writingDocumented overviewLast checked Oct 31, 2026
AI writing assistant that checks grammar, clarity, tone and plagiarism and rewrites text in a browser extension, desktop apps, mobile apps and Microsoft Office and Google Docs integrations.
Our take: Use Grammarly when you want suggestions inside the apps you already write in. Start on Free (100 AI prompts per month) and move to Pro only if you need full-sentence rewrites, tone adjustment or plagiarism and AI-text detection.
Main limitation: Grammarly is cloud-based and needs an internet connection; the official plans page does not list a refund beyond what the law requires.
