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.

The platform is focused exclusively on long-form writing and lacks the template libraries and marketing-specific tools that platforms like Jasper or Copy.ai offer for business content.
Smaller user community and development team compared to major AI writing platforms means slower feature development and fewer integrations with other tools in the content workflow.
No mobile app or offline mode currently available, which limits writers who prefer to draft on tablets or need to write without internet connectivity.
