Quick Verdict
4.4/5

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.

What is Grammarly?

Grammarly has evolved from a simple grammar checker into a comprehensive AI writing assistant. In 2026, Grammarly GrammarlyGO — its generative AI feature — can draft emails, rewrite sentences for tone and clarity, and even generate full documents. But Grammarly's core strength remains what it's always been: making sure everything you write is error-free, clear, and appropriate for your audience.
