Grammarly

What is it?

Grammarly is an AI writing assistant that checks your spelling, grammar, punctuation, and clarity as you type. It works everywhere you write, from email clients and social media to documents and coding IDEs, offering suggestions that improve the overall quality of your text.

How it works

As you type, Grammarly analyzes your writing in real time using a mix of rule-based checks and machine learning. It flags errors, explains why something reads awkwardly, and offers one-click fixes, along with tone and formality feedback that matches your intended audience.

Beyond grammar

Modern Grammarly does far more than correct typos. It can rewrite sentences for clarity, adjust tone, detect plagiarism, generate responses, and even produce full drafts with generative AI, acting as a complete writing coach rather than a simple spell checker.

Who uses it

Professionals, students, and non-native English speakers rely on Grammarly to make their writing polished and confident. Because the free version already covers essential corrections, it has become a default tool for anyone who communicates in writing every day.
