Grammarly Review

// Writing Updated: Dec 2025
Industry Standard

I've been using Grammarly for years, and it's evolved from a simple grammar checker into a comprehensive AI writing assistant with 8 specialized AI agents launched in August 2025. With 30M+ users and 4.53/5 rating across 8 review platforms, it's become the industry standard for polishing business writing. The platform delivers a documented 17x ROI and saves users an average of 19 working days annually-that's roughly 3.65 hours per week recovered.

Feature Analysis

I'm consistently impressed by how Grammarly has evolved beyond basic grammar checking. The August 2025 launch of 8 specialized AI agents (Reader Reactions, Grader, Citation Finder, Paraphraser) transformed it into a document-based writing environment. The platform's strength lies in its cross-platform consistency-identical suggestions whether you're writing in Gmail, Google Docs, Word, or Slack. The Pro tier's 1,000 monthly AI prompts is genuinely generous compared to competitors who cap at 100-200.

Writing Assistance

Excellent

Advanced grammar, spelling, punctuation checks with full-sentence rewrites and vocabulary enhancement. 8 specialized AI agents handle everything from citation finding to tone grading.

Cross-Platform Integration

Excellent

Browser extension, desktop app, mobile app, MS Office (Word + Outlook), Google Docs integration. Works consistently across all platforms with real-time suggestions.

Team Collaboration

Excellent

Style guides, brand tone, snippets (reusable content), and usage analytics for Enterprise. Supports 1-149 members on Pro, unlimited on Enterprise with granular permissions.

AI Content Generation

Good

100-1,000 prompts/month depending on tier. Document-based AI assistant with specialized agents. Enterprise gets custom models and 2,000+ prompts.

Pricing Value

Excellent

$30/month for Pro (60% off annually to $12/month). Free tier is surprisingly capable with 100 AI prompts. 17x documented ROI makes it cost-effective.

The Honest Truth

What We Love
  • Industry-leading accuracy - 4.7/5 rating on G2 with 12K+ reviews. Advanced grammar and punctuation detection outperforms competitors in blind tests.
  • Generous AI prompt quotas - 1,000 prompts/month on Pro tier vs competitors' 100-200. Enterprise gets 2,000+ with custom models.
  • Truly cross-platform - Consistent experience across browser, desktop, mobile, MS Office, Google Docs. Browser extension works on 500K+ sites.
  • Documented ROI - 17x ROI backed by case studies. Users save 19 working days annually (3.65 hours/week). 76% report increased productivity.
  • Strong team features - Style guides, brand tone, snippets, and analytics. Enterprise gets SSO, audit logs, and granular permissions.
What Could Be Better
  • English-only limitation - Supports US, UK, Canadian, Australian, and Indian English variants, but no other languages. Multilingual teams need alternatives like DeepL.
  • Can be overly prescriptive - Flags intentional grammar bends in creative writing or dialogue. Technical writers with domain jargon find it intrusive.
  • Expensive for individuals - $30/month for Pro (even at $12/month annually) is pricey for casual users. Free tier's 100 prompts run out quickly.
  • No offline mode - Requires internet connection. Desktop app still needs connectivity for AI features and real-time checks.

Frequently Asked Questions

No, Grammarly requires an internet connection for all features including the desktop app. The AI-powered suggestions and real-time grammar checking depend on cloud processing. If you need offline functionality, consider Hemingway Editor or ProWritingAid's desktop app.
For business writers and teams, yes-the 17x ROI and 3.65 hours/week time savings justify the cost. Individual users should evaluate based on writing volume: if you're writing 10+ documents/week, the 1,000 AI prompts and plagiarism detection pay for themselves. Casual users can stick with the free tier's 100 prompts.
Yes, but only on Pro and Enterprise tiers. The plagiarism checker scans against 16 billion web pages and databases. Free tier users don't get this feature. Academic users should note that Grammarly's Citation Finder agent (launched Aug 2025) also helps format citations correctly.
No, Grammarly only supports English (US, UK, Canadian, Australian, and Indian variants). Multilingual teams needing translation and grammar checking in other languages should consider DeepL, Smartcat, or language-specific tools.
Grammarly offers more comprehensive all-in-one writing assistance (grammar, tone, plagiarism, 8 AI agents) while QuillBot specializes in paraphrasing with 7 modes and unlimited AI at $20/month. Choose Grammarly for business writing consistency, QuillBot for academic paraphrasing and affordability.
Launched in August 2025, Grammarly's AI agents include Reader Reactions (predicts audience response), Grader (scores writing quality), Citation Finder (formats citations), Paraphraser (rewrites sentences), and 4 others. These agents work within the new document-based interface to provide specialized assistance beyond basic grammar checking.

Final Verdict

4.5/5
Our Rating

The industry standard for business writing-worth every penny

After years of using Grammarly across teams and personal projects, I can confidently say it earns its 4.53/5 rating. The August 2025 launch of 8 specialized AI agents transformed it from a grammar checker into a complete writing environment. Yes, $30/month is expensive for individuals (though $12/month annually is reasonable), but the 17x ROI and 3.65 hours/week saved make it a no-brainer for business users. The free tier with 100 AI prompts is genuinely useful for light users, and the 1,000 prompts on Pro beats competitors by 5-10x. If you're a creative writer or need multilingual support, look elsewhere-but for polished business communication, Grammarly remains the gold standard.
