AI-powered writing assistant for grammar, spelling, tone, and style. Works across browsers, desktop apps, and mobile with real-time suggestions.
Our take
Grammarly has evolved well beyond spell-checking into a comprehensive writing assistant. The real-time suggestions for clarity, tone, and engagement genuinely improve writing quality, and the browser extension means it works everywhere you write. The generative AI features for rewriting and drafting are useful additions. At $12/month, the Premium plan is well-priced for professionals who write frequently. The limitation is that Grammarly is focused on polishing existing writing, not generating new content — for that, you need ChatGPT or Claude. Best for professionals who want to write better, not just faster.
