Grammar, clarity, and tone everywhere you type

Grammarly Pro

The most focused tool for writing quality: grammar, tone, and rewrites that work everywhere you type, plus team style guides, at $12/user/mo annual. Narrower than a full AI assistant, the prompt cap has no top-up, and auto-renewal billing catches people out.

The writing layer for teams that send a high volume of email, proposals, client updates, and support replies and want them to read well every time. Grammarly's edge over a generic spell-checker is depth: grammar, clarity, conciseness, tone, and full-sentence rewrites, and it follows you almost everywhere you type, browser, desktop, mobile keyboard, Google Docs, Word, and email, rather than living in one app. Team features like a shared style guide, brand tones, and snippets keep a small team's voice consistent, and it's especially helpful for non-native English writers. The catches are commercial, not linguistic: the 2,000 monthly AI-prompt cap has no top-up, monthly billing costs 2.5x the annual rate, and auto-renewal draws complaints. It's a polish tool, not a research or document suite, so pair it with a general assistant.

What we like

• ✓The most focused, polished tool for English writing quality — grammar, clarity, tone, and rewrites that generic spell-checkers miss
• ✓Works almost everywhere you type: browser, desktop, mobile keyboard, Google Docs, Word, and email, not just one app
• ✓Generous 2,000 monthly AI prompts on Pro — most individual writers never hit the cap
• ✓Team features (shared style guide, brand tones, snippets, analytics) give small teams a consistent voice without Enterprise pricing
• ✓Especially helpful for non-native English speakers, with fluency suggestions and full-sentence rewrites; rated 4.7/5 by daily users on G2

Trade-offs

• −The 2,000 monthly AI-prompt cap has no published top-up — heavy AI users must wait for the reset or move to Enterprise for unlimited
• −Monthly billing is $30/mo, two and a half times the $12 annual rate, so the headline price requires a yearly commitment
• −Refunds are issued only when legally required, and surprise auto-renewal charges are a frequent, well-documented complaint
• −It is a writing-assistance layer, not a research tool or document suite — narrower in scope than ChatGPT, Copilot, or Notion AI
• −Enterprise security (SSO, SCIM, DLP, HIPAA) is not available on Pro, so regulated teams must move up a tier
