Alternatives to Grammarly
The grammar-checking incumbent
Grammarly ranks #1 of 9 in AI writing assistants, with an Alt Score of 86. It is proprietary, freemium from $12/month (billed annually) and available on Windows, macOS, Web, Browser extension, iOS and Android. 9 of 10 checklist rows are verified against a public source.
Individuals (students, professionals, everyday writers) and teams or organizations across departments like marketing, sales, HR, and support who write regularly across email, docs, and other apps.
Real-time grammar, spelling, and punctuation correction alongside clarity, tone, and style suggestions. AI-assisted rewriting and generation for drafting, rephrasing, or adjusting tone while preserving the writer's voice. Additional tools include plagiarism checking, AI-content detection, and citation generation.
Grammarly runs as a browser extension, desktop app, or plugin for tools like Google Docs and Microsoft Office, underlining issues and offering inline suggestions as you type. Users accept, reject, or rewrite flagged text, and can prompt the AI directly for rewrites or new content.
