Pros

Works seamlessly across 500,000+ apps and websites through browser extensions, desktop apps, and mobile keyboards, providing consistent writing assistance everywhere you type.
Context-aware suggestions adapt to your writing goals, audience, and tone, delivering genuinely useful feedback rather than generic grammar rules that ignore intent.
GrammarlyGO integrates generative AI directly into the writing workflow, allowing users to compose, rewrite, and ideate without leaving their current application.
The tone detection feature provides real-time feedback on how your writing will be perceived by readers, helping you strike the right emotional note in sensitive communications.

The ability to search your entire screen and audio history with natural language queries is genuinely transformative, enabling perfect recall of anything seen, said, or heard on your computer.
All data is stored and processed locally on your Mac, providing strong privacy protection since recordings never leave your device or get sent to external servers.
Meeting intelligence works with any video conferencing platform through screen capture rather than meeting bots, providing universal compatibility without integrations or permissions.
The compression technology is remarkably efficient, storing months of continuous screen recording in surprisingly little disk space without noticeable performance impact.

Cons

The Premium plan at $12 per month (annual billing) may feel expensive for individual users, especially students, considering that basic grammar checking is available in many free tools.
Grammarly can occasionally be overly prescriptive with style suggestions, flagging intentional stylistic choices like sentence fragments, colloquialisms, or creative phrasing as errors.
The generative AI features in GrammarlyGO, while convenient, are less capable than dedicated AI assistants like ChatGPT or Claude for complex writing tasks, long-form content, or creative work.

Currently limited to macOS only, excluding Windows and Linux users from the platform entirely, and there is no mobile companion app for capturing on-device mobile activity.
The concept of continuous screen recording raises legitimate privacy and security concerns, particularly in corporate environments where screen content may include sensitive or confidential information.
The subscription price is relatively high for a productivity tool, and the value proposition requires consistent daily use to justify the cost compared to traditional note-taking and search approaches.
