Cons

Despite improvements, ChatGPT can still occasionally generate plausible-sounding but factually incorrect information, requiring users to verify critical claims independently.
The free tier imposes usage limits during peak hours, and access to the most advanced models like GPT-4o can be throttled, pushing users toward the paid plan.
Conversation context can degrade in very long threads, sometimes causing the model to forget earlier instructions or details discussed many messages ago.

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.
