Grammarly: Complete Review

Grammarly has been the default writing assistant for over 15 years, and its continued evolution shows no signs of stopping. What started as a grammar checker has grown into a comprehensive writing platform that handles everything from basic spelling to generative AI content creation. For anyone who writes regularly in English, it is one of the most useful tools available.

Core Writing Assistance

At its foundation, Grammarly catches mistakes that matter. Grammar, spelling, and punctuation errors are flagged in real time with clear explanations of why something is wrong and how to fix it. The tone detection feature analyzes your writing to tell you how it sounds to readers, professional, friendly, confident, or otherwise. This is genuinely useful for emails and business communication where tone matters.

AI Expansion

Grammarly's 2025 expansion into generative AI significantly broadened its capabilities. Users can now generate essays from scratch, insert citations, and even predict grades based on course criteria. The AI also helps rewrite full sentences for clarity and fluency. These features position Grammarly as more than just a checker, it becomes a writing partner.

Plagiarism and Authorship

The Pro plan includes plagiarism detection that checks text against billions of web pages and academic papers. The authorship tool classifies text as human-written, AI-generated, or a mix, which is increasingly important in academic and professional settings.

Platform Coverage

Grammarly works virtually everywhere you write. Browser extensions catch errors in web forms and email. The Google Docs add-on provides real-time suggestions in documents. Desktop apps work across Microsoft Office and other applications. Mobile apps cover on-the-go writing.

Pricing

The free tier handles basic grammar and spelling. Pro at $12/month is affordable for most users and adds the features that matter most. Enterprise adds the security and administration that organizations need.
