Grammarly Review
AI writing assistant for grammar, clarity, tone, and style
Grammarly is the best AI grammar checker and writing polish tool in 2026. The free tier is genuinely useful for everyday writing; Premium at $12/month is worth it for professionals who write frequently. It's not a replacement for a generative AI like Claude, but nothing beats it for catching errors and improving clarity.

- ""The most accurate grammar checker available
- ""Tone detection helps match communication style to context
Notable Cons

What is Grammarly?
Grammarly has evolved from a simple grammar checker into a comprehensive AI writing assistant.
