Grammarly review
AI writing assistant for grammar, clarity, tone and rewrites that works across your apps, now part of Superhuman.
⚡ Quick verdict
Grammarly is still the easiest way to catch mistakes and polish writing across every app you use. The free plan handles grammar and spelling well; Pro at $12 per month (billed annually) adds full-sentence rewrites, tone adjustments and 2,000 AI prompts, which is worth it for heavy writers. Avoid monthly billing at $30. For long-form AI drafting, a chatbot like ChatGPT or Claude does more.
