What Is Grammarly?

Grammarly is the world's most recognized writing assistant. For years, it has corrected grammar, punctuation, and style errors in real time, integrated into the browser and major writing applications. The Pro version adds advanced style suggestions, plagiarism detection, and generative AI to rewrite passages or generate content.

Strengths

Real-Time Grammar Correction

In English, Grammarly remains the reference. Error detection, style suggestions, and tone consistency are excellent.

Universal Integration

Browser extension, Word plugin, Gmail integration, Google Docs, Notion. Grammarly is present wherever you write, no copy-pasting needed.

Useful Free Plan

The free plan covers basic English correction. Sufficient for most common corrections without paying.

Limitations

High Price for What It Does in 2026

At ~$27/month, Grammarly is more expensive than Claude or ChatGPT which do the same thing better on complex tasks. Grammarly's specific value is real-time integration across all tools, not LLM power.

Weak Outside English

Grammarly is almost exclusively optimized for English. For French or other languages, it detects many errors but corrections are less reliable.

Pricing

Free plan for basic correction. Pro plan at around $27/month. Business plan for teams. Check grammarly.com.

Alternatives

Grammarly = real-time correction in all editors. DeepL Write alternative (deepl.com) = $9/month, better for French and other languages. Claude alternative (claude.com) = $18/month, more powerful for rewriting but not natively integrated in all editors.

Verdict

Grammarly is still relevant for English speakers who write professional English every day. Integration is its main advantage. For non-English speakers or multilingual users, DeepL Write or a general LLM assistant offer more for less.
