What is Grammarly?
Grammarly is an AI-powered writing assistant that checks grammar, spelling, punctuation, clarity, tone, and style in real time — across your browser, email client, Google Docs, Microsoft Word, and 500+ other apps. It was founded in 2009 and now has over 30 million daily active users.
In recent years, Grammarly has evolved from a grammar checker into a full AI writing assistant. The Premium plan includes rewrite suggestions, tone detection, full sentence rewrites, and an AI writing generation feature that can produce entire paragraphs from a prompt.

Final Verdict
Yes — unconditionally for the free plan. For Premium, yes if you write professionally or communicate with clients and colleagues daily. The AI suggestions save real time and the tone detection alone has saved me from sending emails that read more harshly than intended.
Skip Premium if you only write casually or already use a dedicated AI writing tool for content creation.
