Grammarly is the writing assistant everyone knows - that little green icon checking your emails, documents, and social posts for errors. After years of evolution, it's grown from a spell-checker into a comprehensive writing improvement tool with AI generation capabilities. **The Ubiquitous Helper** Grammarly's greatest strength is presence. Install the browser extension, and it works on every website - Gmail, LinkedIn, Twitter, Google Docs, Slack. Add the desktop app, and it covers Word, Outlook, and other applications. The mobile keyboard extends coverage to texts and mobile apps. This everywhere-you-write coverage is unmatched. **Beyond Grammar** Modern Grammarly does far more than fix typos. It suggests rewriting wordy sentences for clarity. It detects whether your tone comes across as confident, friendly, or formal. It flags potentially unclear phrases. For professional communication, these higher-level suggestions often matter more than catching a missing comma. **The Tone Detector** Arguably Grammarly's most underrated feature. Before sending that email to your boss, see if it reads as "direct" when you meant "friendly" - and get suggestions to adjust. For anyone who's agonized over how a message might be received, this reduces anxiety significantly. **Pro Upgrades** The paid tier adds full-sentence rewrites, plagiarism detection, and vocabulary enhancement. The generative AI feature (2,000 prompts/month) helps draft content from scratch, though it's not as capable as dedicated AI writers like Jasper or Copy.ai. **For Teams** Business plans add brand style guides - define your company's terminology, formatting preferences, and voice. Analytics show team writing patterns and areas for improvement. For organizations managing brand consistency, these features add genuine value. **Pricing Realities** Free: Grammar, spelling, conciseness, basic tone Pro: $12/month (annual) or $30/month - adds rewrites, plagiarism, advanced suggestions Business: $15/user/month (annual) - adds style guides, analytics, admin controls **The Limitations** Grammarly suggestions aren't infallible. Accept everything blindly, and you might strip personality from creative writing or introduce awkward phrasings. It's best used as a second pair of eyes, not an autopilot. **Verdict** Grammarly remains the gold standard for writing assistance integrated into everyday workflows. The free tier handles basics well; Pro is worthwhile for professionals who write frequently. For AI content generation, dedicated tools outperform it - but for polishing and error-catching across all your writing, Grammarly's ubiquity is unbeatable.
