Key Features of Grammarly
Real-Time Grammar and Spelling Correction
At its core, Grammarly excels at catching grammar and spelling errors as you type. The browser extension works across Gmail, LinkedIn, Google Docs, Notion, and most web-based editors without requiring you to copy-paste text into a separate tool. The corrections are contextual—Grammarly explains why something might be incorrect, helping you learn and improve over time.
Full-Sentence Rewrites (Pro)
One of Grammarly is most powerful features is its ability to suggest complete sentence rewrites rather than just isolated corrections. The 2026 update brings a smarter contextual engine that matches your intended tone. Instead of mechanical replacements, Grammarly now offers rewrites that sound natural while improving clarity and conciseness.
Tone Detection
The tone detector is particularly valuable for professional communication. You set your intended tone (professional, confident, friendly, empathetic, etc.), and Grammarly flags language that does not match.

Performance and Reliability
