What is Grammarly?
Grammarly has become the default writing assistant for millions, and for good reason. It goes far beyond basic spell-check to analyze grammar, punctuation, clarity, engagement, and delivery – all in real-time as you type. The browser extension works everywhere: Gmail, Google Docs, LinkedIn, Slack, and virtually any text field online.
What sets Grammarly apart from competitors is its contextual understanding. It doesn't just flag errors – it explains why something is wrong and offers multiple suggestions. The tone detector is genuinely useful, catching when your email sounds more aggressive than intended. Premium adds plagiarism detection, vocabulary enhancement, and genre-specific writing style adjustments.
The free tier is surprisingly capable for casual users, catching most grammar and spelling issues. But professionals will want Premium for the full rewrite suggestions, tone adjustments, and plagiarism checker. Business plans add team analytics and style guides for brand consistency.
