Our verdict on Grammarly
Grammarly is an AI-powered writing assistant for individuals, professionals, teams, and educational users. It checks grammar, spelling, punctuation, clarity, fluency, wordiness, style, and tone across its online Editor, desktop applications, websites, browser extensions, and mobile devices. Its scope suits people who need writing support in more than one environment, from everyday messages and documents to workplace content governed by shared style preferences.
The plan structure gives users a clear entry point. The Free plan costs $0 per month and includes grammar and spelling corrections, tone detection, and 100 AI prompts per month. Pro costs $12 per member per month when billed annually, adding full-sentence rewrites, tone adjustments, unlimited personalized suggestions, plagiarism and AI-generated-text detection, 2,000 AI prompts per member per month, plus team style guides, brand tones, snippets, and analytics. Enterprise adds unlimited members, dedicated support, custom roles and permissions, data loss prevention, confidential mode, and contact-sales pricing. A 7-day free trial is also available.
Platform coverage is a central strength. Grammarly is available on web, Windows, macOS, iOS, Android, and through a Chrome extension, with integrations for Microsoft Word, Microsoft Outlook, Google Docs, Gmail, Slack, Salesforce, Microsoft PowerPoint, LinkedIn, Microsoft Teams, Google Sheets, Zendesk, and Jira. That breadth makes it a practical fit for users who move between documents, email, collaboration tools, and customer or business systems. Choose Grammarly when you want one writing layer spanning personal and team workflows. Consider another option if you only need basic correction and do not need tone, rewriting, AI prompts, detection tools, or cross-platform coverage.
