Cons

Claude currently lacks real-time web browsing and a plugin ecosystem, meaning it cannot fetch live data or integrate with third-party services the way some competitors can.
Image generation is not natively supported, so users who need visual content creation must look elsewhere or use Claude in conjunction with dedicated image tools.

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.
