AISH Bottom Line
Grammarly works across 1 million apps and websites via a Chrome extension and native desktop apps, catching real-time grammar and style issues as users write. Support for 20+ languages covers both grammar and spelling in all of them, plus in-line translation to 19 more without leaving the writing context. Eight AI agents handle distinct writing tasks: Citation Finder for research, AI Grader for rubric-aligned feedback, Plagiarism Checker for academic integrity, Reader Reactions to test audience response, and four more for specific stages of revision. Pro costs $12/month annually, with Enterprise offering unlimited AI prompts and BYOK encryption for organizations.
Pros & Cons
Pros
Works Across 1 Million+ Apps Without Switching Context
The Chrome extension and desktop app cover Gmail, Google Docs, Slack, Outlook, Teams, and any website. Writing assistance travels with the user rather than requiring a separate tab or copy-paste workflow. Why it matters: In-context correction reduces the friction of checking writing quality, making it more likely writers use the tool consistently rather than skipping it for speed.
Multilingual Support Now Covers 20+ Languages
Real-time grammar and spelling corrections in over 20 languages, with full clarity and fluency suggestions in 6. In-line translation across 19 languages works without leaving the active writing surface. Expanded to 17 additional languages in March 2026. Why it matters: Teams writing in multiple languages get consistent quality support without switching tools or hiring multilingual proofreaders.
Eight AI Agents Covering Distinct Writing Stages
Reader Reactions, AI Grader, Citation Finder, Expert Review, Proofreader, Plagiarism Checker, AI Detector, and Paraphraser each address a specific writing task. They run inside Grammarly Docs without prompting. Why it matters: Specialized agents for each writing stage address specific quality problems rather than relying on a single general-purpose model.
Cons
AI Prompts Capped at 2,000 Per Month on Pro
Pro subscribers hit a hard cap of 2,000 AI prompts per billing period. Professional writers using generative features throughout the workday can reach this limit before the month ends. Unlimited prompts are only available on Enterprise. Impact: Professional writers who rely heavily on generative AI features will exhaust their monthly prompt allowance, forcing either usage restraint or Enterprise pricing.
No Official Automation Integrations
No Zapier, Make, n8n, or Pabbly Connect integrations exist. Grammarly operates within its own extension and API surface. Teams needing Grammarly outputs inside automated workflows have no official route. Impact: Teams wanting to incorporate Grammarly corrections into content pipelines or automated workflows cannot do so through official channels.
