Cons

Strict content filters can sometimes interrupt conversations unexpectedly, even in non-problematic contexts, which can break immersion and frustrate users seeking creative freedom.
Characters can fall into repetitive response patterns during extended conversations, occasionally recycling similar phrases or narrative structures across sessions.
Since the platform prioritizes personality and engagement over factual accuracy, it should not be relied upon for research, homework, or any task requiring truthful information.

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.
