“Essential writing assistant. Best grammar checking with useful AI features.”
Grammarly remains the gold standard for writing assistance. The free tier catches more errors than competitors, and Premium adds valuable style suggestions. The new AI features (GrammarlyGO) bring generative capabilities, though they feel bolted-on compared to native AI tools. For anyone writing professionally in English, Grammarly is essentially mandatory.
