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 free plan limits recording time to 300 minutes per month and 30 minutes per conversation, which is insufficient for users with multiple long meetings per week.
Transcription accuracy drops noticeably with heavy accents, technical jargon, and poor audio quality, and the platform primarily supports English with limited multilingual capabilities.
The AI summaries, while useful, can sometimes miss nuanced points or misidentify the importance of certain discussion items, requiring manual review for high-stakes meeting documentation.
