Grammarly

Grammarly is an AI-powered intelligent English writing assistant. Its core features include real-time grammar checking, writing style optimization, plagiarism detection, and AI text generation and rewriting, all aimed at improving the quality and efficiency of your English written communication.

Grammarly offers a free version with basic grammar, spelling, and punctuation checks. The paid Premium adds advanced features such as style optimization, clarity suggestions, sentence rewrites, plagiarism detection, and more usage of AI prompts.

Grammarly works across over 500,000 websites and apps primarily through browser extensions, desktop apps, and mobile keyboards, and can integrate with Microsoft Office, Google Docs, and more. It focuses on English writing assistance and does not support Chinese grammar checks.

Grammarly commits to user privacy and security, stating that they do not sell user data or use it for ads or model training. Users can also disable checks in certain apps to protect sensitive text.

Grammarly is well-suited for students, professionals, content creators, and non-native speakers. For English learners, it not only corrects errors but also helps users understand and improve writing through explanations and suggestions, making it an effective learning aid.

Users can leverage AI prompts to generate text ideas or to rewrite and paraphrase sentences. The free version has limited AI features; Premium typically provides more monthly usage or broader feature access.
