Reviewers largely see Grammarly as a reliable daily writing aid that catches grammar, spelling, and clarity issues quickly, works across browsers and apps, and is especially helpful for emails, reports, assignments, and non-native English writing. Many say it improves confidence, speed, and polish, with useful tone and rephrasing suggestions. The main complaints are familiar: some prompts feel intrusive, premium features are gated, the extension or plugin can integrate awkwardly, and a few users say suggestions can miss context, flatten personal style, or even hurt performance on some devices.
