What Is Grammarly?
Grammarly is an AI writing assistant that checks grammar, spelling, tone, clarity, and style in real time. It works across browsers, Microsoft Word, Google Docs, email clients, and mobile apps. In 2026 it has evolved beyond grammar checking into a full AI writing suite with rewriting, plagiarism detection, and AI text detection.
Honest Review
Grammarly’s free tier is genuinely useful — not a crippled demo. Pro at $12/month annually is outstanding value, unlocking 2,000 AI prompts, advanced rewrites, plagiarism detection, and tone adjustment. The biggest trap is monthly billing at $30/month — always choose annual. Grammarly holds a 4.7/5 on G2 from nearly 13,000 reviews, making it one of the most trusted writing tools available.
