Our verdict

Outwrite works inside Gmail, LinkedIn, Medium, WordPress, and most places you type online, catching spelling and grammar issues, suggesting synonyms, and reporting readability and grade-level stats for free. The paraphrasing tool, style and structure suggestions, and plagiarism checker all sit behind the Pro upgrade, so the free version stays a solid proofreader rather than a full rewriting assistant. It supports French, Spanish, and English, and with 113 ratings and over a million users, it has more of a track record than most extensions in this space.
