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.

Pricing starts at $19 per month for the Pro plan with limited AI credits, and heavy users during intensive writing periods may need the Max plan at $44-59 per month, making it expensive for hobbyist writers.
The tool is exclusively focused on fiction and creative writing, offering little value for users who also need help with business writing, marketing content, emails, or other non-fiction tasks.
AI-generated fiction prose, while impressive, can sometimes feel formulaic or lean toward genre clichés, requiring authors to carefully curate and revise output to maintain their unique literary voice.
