What It Does
Grammarly checks your writing for grammar, spelling, punctuation, clarity, and tone in real time. The free tier handles correctness and basic clarity. Premium adds tone detection, full-sentence rewrites, vocabulary suggestions, and a plagiarism checker. The AI assistant can rewrite paragraphs, adjust formality, and shorten or expand text. It works everywhere you type—email, Google Docs, Slack, LinkedIn, even code comments.
